Threading is a precise, chemical-free method of removing unwanted hair, most often used to shape the eyebrows and to tidy the upper lip, chin, cheeks and sides of the face. A trained technician twists a length of fine cotton thread and rolls it across the skin, catching individual hairs and lifting them cleanly from the follicle in neat rows. Because it removes hair at the root, results typically last longer than shaving, and because no wax or heat touches the skin, many people find it gentler on sensitive or reactive areas. It is one of the lower-risk beauty treatments, but the eye and brow area is delicate, so skill, hygiene and honest advice about your skin still matter. Threading suits most skin types and can be tailored to your preference, from a subtle clean-up to a defined reshape. It does not treat any skin condition and is purely a hair-removal and grooming service. A good practitioner will talk through the shape you want, check that your skin is healthy and intact, and work with fresh thread to keep the treatment clean and comfortable.
In most cases little preparation is needed. If you are reshaping your brows, letting the hair grow for a couple of weeks beforehand gives the technician more to work with and a better result. Arrive with a clean, make-up-free face where possible, as this keeps the area hygienic and lets the practitioner see your natural hair pattern. It helps to bring a reference photo or to be ready to describe the shape and thickness you would like, so the outcome matches your expectations. Avoid strong exfoliants, retinoids, acids or sunbeds and heavy sun exposure for a day or two beforehand, as these can leave skin more sensitive or fragile. If you have recently had a facial, peel or laser in the same area, mention this. Tell your technician about any skin conditions, medicines or recent treatments at the start, so they can adjust their approach or advise waiting if your skin is not suitable that day.
You will usually sit or lie back while the technician holds the skin taut with one hand and works a twisted cotton thread across the area with the other. The thread rolls over the skin and lifts several hairs at a time directly from the root, following the shape you have agreed together. You may be asked to hold your own skin or eyelid gently in place to help keep the area steady and the lines clean. Brow shaping typically takes only a few minutes; larger areas such as the full face take a little longer. A skilled practitioner works methodically, checking the shape and symmetry as they go and pausing to show you progress if you wish. The sensation is a quick, repeated light scratching or plucking feeling rather than the pull of wax. Fresh thread should be used for you, and the technician should have clean hands and a tidy workspace throughout.
Threading has minimal aftercare, but the follicles are briefly open afterwards, so a little care helps prevent irritation. Some redness or small pink bumps are normal and typically settle within a few hours to a day. Avoid touching or rubbing the area with unwashed hands, and try to keep heavy make-up off freshly threaded skin for the rest of the day to lower the risk of blocked pores or infection. A cool compress or a simple soothing gel such as aloe vera can calm any warmth, though some people prefer to leave the skin bare. For around 24 hours it is sensible to avoid saunas, steam rooms, hot workouts, swimming pools, sunbeds and strong sun, as heat, sweat and UV can aggravate sensitive skin. Hold off on exfoliating acids and retinoids on the area for a day or so. If you notice unusual swelling, spreading redness or signs of infection, seek advice from a pharmacist or GP.
Threading is low-risk, but good hygiene is what keeps it safe, because the thread runs directly across the skin and briefly opens the follicles. Fresh, clean cotton thread should be used for each client and never reused between people, and the technician should have clean hands and a clean working area. Choose a practitioner who is trained and experienced, ideally insured, and who works in a clean, professional setting. A careful technician will check that your skin is healthy and intact before starting and will not thread over broken skin, active acne, cold sores, sunburn, eczema or any inflamed or infected area, as this can spread bacteria or worsen the skin. The eye and brow area is delicate, so precision and steady skin tension matter to avoid nicks or catching the skin. If anything about the cleanliness or the practitioner's confidence feels off, it is reasonable to pause and ask questions before going ahead.
Threading is a cosmetic hair-removal service and is not a substitute for medical care, but a few health factors are worth flagging to your technician. If you take the acne medicine isotretinoin (Roaccutane) or have recently finished it, your skin can be thin and fragile and may lift or tear easily, so many practitioners will decline threading or advise waiting; guidance in this area is debated, so check with your prescriber or a GP first. Let your technician know if you use retinoids or acid exfoliants, take blood thinners or steroids, or have a skin condition such as eczema, psoriasis, rosacea or very reactive skin, as any of these can make skin more sensitive or prone to marking. Recent facials, peels, laser or microneedling in the same area also mean the skin may need time to recover. If you are unsure whether threading is suitable for your skin or medication, speak to a GP or your prescribing clinician before booking.
A skin patch test is not standard for threading, because it uses only cotton thread with no dyes, chemicals or products that commonly trigger allergy. What matters instead is a proper check before the technician starts. Expect a brief consultation covering your skin health, any medicines such as isotretinoin or blood thinners, recent treatments in the area, and the shape you want. The practitioner should look at the skin to confirm it is intact and free of active acne, cold sores, sunburn, eczema or infection before threading over it. These checks reduce the risk of irritation, marking or spreading bacteria, and they protect you and the practitioner if anything were later disputed. Being open about your history at this stage is the best safeguard; if in doubt about a medicine or skin condition, a GP or prescriber can advise whether to proceed.
Be cautious if the thread looks reused between clients, if the technician does not appear to take a fresh length for you, or if their hands and workspace are visibly unclean. It is a warning sign if no one asks about your skin, medicines or recent treatments, or if a practitioner is willing to thread over active acne, cold sores, sunburn, broken or infected skin. Rushed, heavy-handed work that repeatedly catches or nicks the delicate skin around the eyes is a concern, as is a practitioner who dismisses your questions about hygiene or shape, or who cannot explain their training or insurance. Pushy upselling, no consultation and a dirty or chaotic setting are all good reasons to pause and reconsider.
Good practice starts with a clean, tidy setting and a technician with clean hands who takes a fresh length of cotton thread for you. Look for someone trained and experienced who is happy to explain their approach and show they are insured. A good practitioner asks about your skin, medicines and recent treatments, checks the skin is healthy before starting, and talks through the shape you want rather than assuming. They work with steady, controlled tension, check symmetry as they go and pause to let you see progress. Clear, honest aftercare advice and a willingness to say no or reschedule if your skin is not suitable that day are strong signs you are in careful, professional hands.
Most people describe threading as a quick series of light scratching or plucking sensations as each row of hair lifts from the root, rather than the stronger tug of waxing. There can be a brief sting on more sensitive spots such as the upper lip or close to the inner brow, and your eyes may water a little around the brows, which is a normal reflex rather than a sign of harm. First-timers often feel it more, and skin can be more tender around the time of your period. Any discomfort is usually short-lived and eases as soon as the area is finished, often leaving a mild warm or tingly feeling for a short while.
Threading needs little to no downtime and most people return to their day straightaway. It is normal to see some redness, mild tenderness or a few tiny raised bumps immediately afterwards, particularly if it is your first time or the area is sensitive, and this typically fades within a few hours and often within a day. Because the treatment is quick and non-invasive, there is usually no lasting mark. If your skin runs reactive, you may prefer to schedule threading a day or two before an event rather than immediately before, so any short-lived redness has time to settle.
Because threading removes hair from the root, results typically last longer than shaving, commonly around two to four weeks, though this varies with your natural hair growth and cycle. As the hair grows back it tends to feel finer and softer than stubble, and regular threading can make regrowth look more even over time. Most people settle into a rhythm of every three to four weeks for brows to keep a defined shape, or as needed for facial areas. Between visits, avoid over-plucking at home, which can disrupt the shape your technician has created. The intensity of the result is easily tailored, from a light tidy that keeps your natural brow to a more defined reshape, so it is worth discussing your preference each time, especially if your ideal shape changes. Gentle daily brushing and a light moisturiser help keep the brows and surrounding skin in good condition between appointments.
Upper lip waxing is a quick, popular form of temporary hair removal that lifts fine to coarse hair from the root across the top lip. Warm (soft) or hot (hard) wax is applied to the small area, allowed to grip the hair, then removed to take the hairs with it. Because it removes hair below the surface, results usually last longer than shaving or depilatory creams, and regrowth often feels softer over time. Many people choose it for smooth skin ahead of make-up or simply for day-to-day confidence. The upper lip is a delicate, visible area with thin skin, so technique, wax temperature and hygiene matter more than the small size of the zone might suggest. Hard wax is often preferred here because it clings to hair rather than skin, which can reduce discomfort and redness. It is a low-risk beauty treatment for most healthy adults, but it is not suitable for everyone: certain medicines, skin conditions and recent treatments can make skin more fragile. A brief consultation and honest chat about your skin and medical history helps your therapist tailor the approach and keep the experience comfortable and safe.
Let the hair grow to roughly five millimetres, about the length of a grain of rice, so the wax has enough to grip; hair that is too short may be missed. Avoid strong exfoliating actives on the area for a few days beforehand, including retinoids, glycolic or salicylic acid and scrubs, as these thin and sensitise the skin and raise the risk of lifting. Skip sunbeds, sunbathing and fake tan for around twenty-four to forty-eight hours before your appointment, and reschedule if the skin is sunburnt, broken or irritated. Come with a clean, product-free lip area, as oils and heavy moisturiser can stop the wax adhering. Cutting back on caffeine and alcohol on the day may reduce sensitivity for some people. Tell your therapist about any medicines, recent facials or peels, and skin conditions so they can decide whether to proceed, patch test or adjust the wax used.
Your therapist will start by cleansing the upper lip and often dusting it with a little powder to protect the skin and absorb moisture. They may apply a thin pre-wax oil, particularly with hard wax, so it grips hair rather than skin. Warm wax is spread in the direction of hair growth, left to set for a moment, then removed swiftly against the growth while the skin is held taut. The whole treatment usually takes only a few minutes because the area is small. You may feel a brief, sharp tug as each strip or piece is removed, followed quickly by soothing pressure from the therapist's hand, which helps ease the sting. A calming lotion or gel is applied afterwards to reduce redness. A good therapist will check the temperature of the wax on themselves first, work in small sections and never double-dip a used spatula back into the pot, keeping the process hygienic and comfortable.
For the first twenty-four to forty-eight hours the skin is more vulnerable, so treat it gently. Avoid touching or picking at the area, and hold off on make-up, perfumed products and heavy creams over the lip for at least a day to lower the chance of irritation or blocked follicles. Keep away from heat and friction: no hot baths, saunas, steam rooms, swimming pools or vigorous exercise for a day or so, as sweat and heat can irritate freshly waxed skin. Steer clear of direct sun and sunbeds, and once redness settles apply a broad-spectrum SPF, since the skin can be more sun-sensitive. From around day two or three, light exfoliation a couple of times a week and a simple moisturiser help prevent ingrown hairs. If you notice unusual soreness, spots or lifting of skin, keep the area clean and seek advice from your therapist or a pharmacist.
Safety here rests mainly on hygiene, correct wax temperature and honest screening, because the upper lip has thin, delicate skin over a visible area. The wax should be warm, never scalding: overheated wax can burn, and a lip burn is both painful and slow to fade. Choose a clean, professional setting where the therapist washes their hands, wears gloves where appropriate and never double-dips a used spatula back into the wax pot, as re-dipping can transfer bacteria. Single-use spatulas or fresh strips are a good sign. Your therapist should ask about your medical history and current skincare before starting, and should decline or adjust the treatment if your skin is broken, sunburnt, infected or recently exfoliated. If you are new to waxing or have reactive skin, a patch test is a reasonable precaution. When in doubt about a medicine or skin condition, it is always worth checking with your GP or pharmacist first.
Some medicines and conditions make waxing unsuitable or riskier, so share your full history. Oral isotretinoin (Roaccutane) and other oral retinoids thin the skin and greatly increase the risk of tearing or lifting; the widely used professional standard is to avoid facial waxing while taking it and for around six months after stopping, though you should confirm timing with your prescriber. Topical retinoids, recent chemical peels, microdermabrasion or laser on the area also fragilise skin and warrant a delay. Blood-thinning medication can increase bruising, and conditions such as poorly controlled diabetes may slow healing. Active cold sores, eczema, psoriasis, rosacea flares, sunburn or broken skin over the lip mean waxing should wait. Pregnancy, hormonal treatments and some antibiotics can heighten skin sensitivity. Waxing is not a medical treatment and does not diagnose or treat any skin condition. If you are unsure whether a medicine or condition affects your suitability, check with your GP, pharmacist or prescriber before booking.
A patch test is not always routine for a simple wax, but it is sensible for first-time clients, sensitive or reactive skin, or if you use active skincare or have recently had facials or peels. More important is a proper pre-treatment check: your therapist should review your medicines, skin conditions, recent treatments and sun exposure, and inspect the area for broken or irritated skin before applying wax. This matters for both safety and UK liability, because an insured practitioner who skips reasonable screening and causes a burn, tear or reaction could be found at fault in a claim. Remember that skin can also become sensitised over time, so a clear history today does not guarantee no reaction in future. If anything about your skin or health has changed, mention it, even if you have been waxed before.
Be cautious if the therapist double-dips a used spatula back into the wax pot, works from a dirty or cluttered station, or does not wash their hands or change gloves between clients. Wax that feels uncomfortably hot on your skin, or a therapist who does not test the temperature, is a burn risk and a warning sign. Take note if no one asks about your medical history, medicines or recent skincare, or if concerns you raise, such as being on Roaccutane or having a cold sore, are brushed aside. Pressure to proceed on sunburnt, broken or infected skin, reluctance to explain aftercare, or an unwillingness to answer questions about hygiene and training are all reasons to pause and consider going elsewhere.
Good practice looks like a clean, tidy treatment room, visible hand-washing and gloves where appropriate, and single-use or freshly changed spatulas with no double-dipping. A conscientious therapist tests the wax temperature before applying it, works in small sections, holds the skin taut and soothes the area straight afterwards. They will ask about your medical history, medicines, allergies and recent skincare, and be willing to postpone or patch test if that is the safer choice. Clear, honest explanations of what to expect, realistic advice on regrowth, and written or spoken aftercare are all reassuring. Relevant qualifications, professional insurance and membership of a recognised industry body are further signs you are in careful hands.
Most people feel a quick, sharp tug or stinging pinch as the wax is pulled away, since the hairs are lifted from the root. Because the upper lip has thin skin and sits near the nose, this small area can feel more sensitive than others, and your eyes may water briefly, which is a normal reflex rather than a sign of harm. The sting usually fades within seconds, especially when the therapist presses a hand over the area straight afterwards. You can expect some warmth, mild throbbing and pinkness for a short while, and occasionally tiny bumps. Sensitivity varies from person to person and can be greater around your period or if you are new to waxing.
There is essentially no downtime with upper lip waxing, which is part of its appeal. Most people return to normal activities straight away. Expect some redness, warmth and mild tenderness for anywhere from twenty minutes to a few hours, and occasionally small raised bumps where hairs have been removed, which typically settle within a day. Those with sensitive or reactive skin may stay pink a little longer. A cool compress and a fragrance-free soothing gel help. Because the skin is briefly more delicate, it is sensible to plan waxing a day or two before an important event rather than on the day itself.
Upper lip waxing typically keeps the area smooth for around two to four weeks, though this varies with your natural hair cycle and how quickly you regrow. Because the hair is removed from the root, regrowth tends to feel finer and softer than the stubble left by shaving, and over time some people find hair grows back a little sparser. For best results, let the hair reach about five millimetres before rebooking rather than waxing too soon, and try to keep to a regular pattern so more hairs are caught in the same growth phase. Gentle exfoliation a couple of times a week and daily moisturising between appointments help prevent ingrown hairs and keep skin comfortable. Waxing does not permanently remove hair; if you want a longer-term reduction, laser or electrolysis with a qualified provider may be worth discussing. Your therapist can tailor frequency and wax type to your skin's sensitivity and your regrowth.
Waxing removes unwanted hair from the root using warm or hot wax, giving smooth skin that typically lasts longer than shaving because the hair has to regrow fully before it reappears. It can be used on the legs, arms, underarms, face (such as the upper lip, chin and brows), back, chest and the bikini or intimate area, with a Brazilian or Hollywood removing most or all of the pubic hair. Practitioners usually work with either strip wax, where fabric or paper strips lift the wax and hair away, or hot (peelable) wax that sets and is removed without strips, which many find gentler for sensitive and intimate areas. Results build over time, and with regular appointments hair often grows back finer and more sparsely for some people, though this varies. Waxing is a well-established beauty treatment rather than a medical one, but it is not suitable for everyone or for every stage of skin health. Some skin conditions, medications and recent treatments make it unsafe, so a good therapist will check your suitability first. Choosing a trained, insured therapist working in clean, hygienic conditions makes a real difference to both your comfort and your safety, and to the quality of the finish you can expect.
Let the hair grow to roughly a quarter of an inch, or about the length of a grain of rice, so the wax can grip it properly; if it is too short it will not lift cleanly, and very long hair can be trimmed first. In most cases it helps to gently exfoliate and moisturise in the days beforehand, but stop moisturising on the day itself and arrive with clean, product-free skin, as oils and creams stop wax adhering. Avoid sunbeds, sunbathing and fake tan in the days before, and do not book waxing over sunburnt, broken or freshly treated skin. Tell your therapist in advance about any medication, skin conditions or recent treatments such as chemical peels, laser or microdermabrasion. Many people find it more comfortable to avoid caffeine and alcohol beforehand and, where relevant, to book outside the most sensitive days of their menstrual cycle. A warm shower beforehand can soften the follicles.
Your therapist will typically start with a short consultation about your health, medication and any previous reactions, then cleanse the area. Warm wax is applied in the direction of hair growth using a spatula, and either a strip is pressed on and removed, or hot wax is left to set slightly and then flicked off, both taken away against the direction of growth to lift the hair from the root. You will feel a quick pull with each section, which passes almost immediately; the therapist often applies gentle pressure straight afterwards to ease it. They should use a fresh spatula each time rather than double-dipping into the pot, and work in an unhurried, methodical way. Afterwards they may tweeze any stray hairs, remove residue and apply a soothing lotion. A full leg or intimate wax takes longer than a lip or brow. A good therapist will keep checking you are comfortable and will explain what they are doing throughout.
For the first 24 to 48 hours the follicles are open and the skin is more sensitive, so treat the area gently. Keep to lukewarm showers rather than hot baths, saunas or steam rooms, and avoid swimming pools for a day or so. Skip perfumed products, deodorant on freshly waxed underarms, make-up over the area, and sunbeds, sunbathing and fake tan while the skin settles. Avoid heavy exercise and tight, non-breathable clothing straight after an intimate wax, as heat, friction and sweat can cause irritation. Wear loose, clean cotton where possible. If the skin feels tender, a cool compress or a plain, fragrance-free soothing gel such as aloe vera can help. From two to three days afterwards, begin gently exfoliating a few times a week and keep the skin moisturised, which helps prevent ingrown hairs. Try not to touch or pick at the area with unwashed hands.
Hygiene is central to safe waxing. Your therapist should wash and sanitise their hands, work in a clean environment, use fresh couch roll and, crucially, never double-dip the spatula back into the wax pot after it has touched your skin, as this can spread bacteria. Choose someone who is trained in waxing and holds professional insurance, and who takes a proper health and medication history before starting rather than pressing ahead regardless. Wax should be tested for temperature so it is comfortably warm, not hot enough to burn. Waxing should only be done on healthy, intact skin, so it should be avoided over cuts, sunburn, active eczema, psoriasis or rosacea flare-ups, moles, warts, varicose veins and recently treated or peeling skin. If anything feels too hot or the environment looks unclean, it is reasonable to stop and ask questions. A patch test may be offered, especially before intimate or sensitive-area waxing.
Some medications and conditions make waxing unsafe because they thin, fragile or over-sensitise the skin, raising the risk of tearing, lifting, bruising or burns. Isotretinoin (Roaccutane) is a key one: skin usually should not be waxed while taking it and for a period after stopping, with around six months commonly advised, though you should check with your prescriber. Topical retinoids and acids such as tretinoin, retinol, adapalene and glycolic acid should be paused on the area beforehand, as should recent chemical peels, laser, IPL or microdermabrasion. Blood-thinning medication, some antibiotics, diabetes, circulatory problems, autoimmune conditions and pregnancy all warrant caution and, where appropriate, a word with your GP first. Waxing is not a treatment for any skin or medical condition and makes no health claims. Always tell your therapist about your full medical history and any medicines, prescribed or over the counter, so they can judge whether it is safe or whether to postpone.
A skin patch test is not routine for every wax, but a thorough consultation and health check before your first appointment matters just as much. Your therapist should ask about medication, skin conditions, allergies (including to ingredients such as rosin or colophony in some waxes), pregnancy, hormonal treatments and recent skin procedures, and inspect the area to confirm the skin is healthy and intact. A small patch test is sensibly offered if you have sensitive or reactive skin, a history of reactions, are pregnant or on hormonal medication, or are trying a new wax type. This protects you from an unexpected reaction and reflects good, insured practice: skipping these checks can leave a therapist at fault if something goes wrong. Sensitivities can also develop over time, so the history should be revisited at repeat visits, not assumed unchanged.
Be cautious if the therapist double-dips the same spatula back into the wax pot, reuses strips between clients, or works in a visibly unclean space without fresh couch roll or clean hands. It is a warning sign if no one asks about your medication, skin conditions or medical history, or if they wax over sunburn, cuts, active eczema or psoriasis, moles or recently peeled skin without hesitation. Wax that feels too hot, being rushed or pressured, dismissing your discomfort, or an unwillingness to answer questions about training, insurance or hygiene are all reasons to pause. Guarantees that waxing will permanently remove hair, or pushing on despite your telling them you take Roaccutane or blood thinners, should also give you real cause for concern.
Good practice looks like a clean, tidy room, freshly sanitised hands, disposable couch roll and a spatula that is used once and never dipped back into the pot. A reassuring therapist takes a proper health and medication history, checks your skin is suitable, tests the wax temperature and explains what they are doing as they go. They hold recognised waxing training and up-to-date professional insurance, are happy to answer questions, and will honestly postpone or decline if waxing is not safe for you that day. They talk you through realistic expectations, tailor the approach to your skin's sensitivity and the area being treated, and send you away with clear aftercare advice. Feeling comfortable to speak up and being checked on throughout are signs of a considerate, professional service.
Waxing involves a quick, sharp pulling sensation as each section of hair is lifted from the root, followed by a brief sting or warmth that usually fades within seconds, eased by the gentle pressure a therapist applies straight after. The warm wax itself feels comfortably hot but should never burn. Sensitive and intimate areas, coarser hair and a first-ever wax tend to feel more intense, while regular waxing often becomes more tolerable as the hair grows back finer. You may feel some tenderness, tingling or warmth for a short while afterwards, and small raised bumps around the follicles are common and normal. Skin can be more sensitive around your menstrual cycle. Tell your therapist at any point if something is too painful.
There is usually little to no real downtime. Most people notice some redness, warmth and small raised bumps around the follicles straight after, particularly on first-time or sensitive-area waxes, and this typically settles within a few hours to a day. More sensitive or intimate areas can stay slightly pink or tender for a little longer. You can generally return to normal activities right away, though it is sensible to avoid heat, heavy sweating and friction for the first day. If redness, swelling or discomfort is getting worse rather than better after a couple of days, or you see signs of infection, seek advice from your therapist or a pharmacist or GP.
Smooth results from waxing typically last around three to six weeks, depending on your natural hair growth cycle and the area treated. Because the hair is removed at the root, regrowth is softer and less stubbly than after shaving, and with regular waxing every four to six weeks many people find growth becomes gradually finer and more sparse, though this varies from person to person and is not guaranteed to be permanent. For the best results, let the hair reach a suitable length between appointments rather than shaving in between, which resets the cycle. Regular gentle exfoliation two to three times a week and daily moisturising between visits help keep skin smooth and reduce ingrown hairs. Booking on a consistent schedule keeps regrowth even and often makes each session more comfortable. Your therapist can tailor the frequency and areas to your hair type, skin sensitivity and how quickly you regrow.
IPL, or intense pulsed light, uses broad-spectrum flashes of light to target colour (pigment) in the skin. Unlike a laser, which uses a single wavelength, IPL delivers a range of wavelengths, which is why the same device can be used for different concerns. It is most commonly used for hair reduction and for skin rejuvenation, helping to soften sun spots, freckles, facial redness, thread veins and the flushing linked to rosacea. The light is absorbed and converted to heat, which disables the hair follicle or breaks down unwanted pigment. Because IPL works on contrast between the target and the surrounding skin, it tends to suit people with lighter skin and darker hair or clearly defined pigment, and it is generally less suitable, and higher risk, for darker or tanned skin, where the light can be absorbed by the skin itself and cause burns or pigment changes. IPL is not a single fixed treatment. A trained practitioner tailors the settings, wavelength filter and energy to your skin tone, the concern being treated and how your skin responds, and a course of sessions is usually needed rather than a one-off. Results build gradually and are best thought of as reduction and improvement rather than permanent removal or a cure.
Book a face-to-face consultation before your first session so the practitioner can assess your skin tone (Fitzpatrick type), review your medical history and carry out a patch test. Avoid sun exposure, sunbeds and fake tan for at least four weeks beforehand, as tanned or recently exposed skin significantly raises the risk of burns and pigment changes; treatment is usually postponed if your skin is tanned. Do not pluck, wax, thread or use epilators for around four to six weeks before hair-removal sessions, because IPL needs the hair root in place, though you can shave. Stop retinoids, strong acids and other exfoliating actives for several days as advised, and tell your practitioner about any medicines or supplements that increase light sensitivity. Come to your appointment with clean skin, free of make-up, moisturiser, deodorant or perfume on the treatment area. If you have any doubts about a medicine or skin condition, check with your GP or prescriber first.
You will usually be asked to confirm there have been no changes to your health, medicines or sun exposure since your consultation. The area is cleansed and often a cool gel is applied, and both you and the practitioner wear protective eyewear, as IPL light can damage the eyes. A handpiece is placed against the skin and delivers pulses of light, typically felt as a warm flick or the snap of an elastic band, with a burst of brightness through the goggles. The practitioner works methodically across the area, checking your skin's reaction as they go and adjusting the energy if needed. A small area such as the upper lip may take only a few minutes, while larger areas or full-face rejuvenation can take twenty to forty-five minutes. Afterwards the skin is cooled and soothed. For pigmentation, treated spots may look darker at first before flaking away over the following days.
Expect the treated skin to feel warm and look pink for a few hours, similar to mild sunburn. Cool the area gently and apply any soothing product your practitioner recommends; avoid rubbing, picking or scratching. For at least a week or two, keep away from heat that raises the skin's temperature, including hot baths and showers, saunas, steam rooms, swimming pools, intense exercise and very hot drinks against the skin. Do not use perfumed products, exfoliating acids, retinoids or make-up on the area until any redness has settled. Where pigment has been treated, let the darkened spots and crusts flake off naturally rather than scrubbing them. Protect the area from the sun completely and use a high-factor broad-spectrum SPF every day, as skin is more vulnerable to pigment changes afterwards. Follow the interval your practitioner advises between sessions, and contact them promptly if you notice blistering, unusual pain or signs of infection.
IPL is an energy-based device treatment, so the biggest safety factors are the practitioner's competence and the settings they use. Choose someone properly trained and qualified in IPL specifically, insured for it and working in a clean, professional setting with well-maintained, calibrated equipment. The most common problems reported are burns, so correct energy settings matched to your skin tone, together with an honest assessment of whether IPL suits you at all, are essential. Accurate Fitzpatrick skin typing, protective eyewear for everyone in the room, and a fresh patch test whenever the area, device head or settings change all reduce risk. IPL is generally higher risk on darker or tanned skin, where burns and pigment changes are more likely, and a good practitioner will decline or adapt treatment rather than press ahead. In some parts of the UK, such as London and parts of Wales and Scotland, laser and IPL premises must be registered or licensed with the local authority, so it is reasonable to ask about this.
IPL is not suitable for everyone, so a full medical history matters. It is generally avoided in pregnancy, on tanned or very dark skin, and over moles, undiagnosed lesions, tattoos or areas of active infection, eczema, psoriasis or cold sores. Several medicines and conditions increase light sensitivity or the risk of pigment problems, including recent isotretinoin (Roaccutane), certain antibiotics, St John's Wort, some acne and photosensitising medications, and conditions such as epilepsy triggered by light or a history of keloid scarring. IPL can worsen melasma and may activate cold sores or other latent infections. If you have a history of skin cancer, a bleeding disorder, are taking blood thinners, or have any concern that has not been checked, speak to your GP or a suitably qualified medical practitioner before booking. IPL is a cosmetic treatment, not a medical diagnosis or cure, and any new, changing or suspicious skin lesion should be assessed by a doctor rather than treated.
Yes. A patch test on a small area of the intended site is standard good practice for IPL and should be done at consultation, usually at least 24 to 48 hours before your first full session. It checks how your skin reacts to the light and energy and helps the practitioner set a safe starting point, reducing the risk of burns and pigment changes. A fresh patch test is also sensible whenever you move to a new body area, or the device, headpiece or settings change, as reactions can differ. A patch test is not a guarantee, and sensitivity can still vary with sun exposure, medicines or hormonal changes, so honest disclosure at every visit matters. From a UK liability point of view, skipping the patch test and consultation can leave a practitioner exposed if a claim arises, which is why reputable providers insist on it.
Be cautious if a provider skips the consultation, medical history or patch test, or is willing to treat tanned skin or press ahead on darker skin without discussing the higher burn and pigment risks. Vague answers about their IPL training, qualifications or insurance, or reluctance to say what device and settings they use, are warning signs, as is equipment that looks poorly maintained or is not calibrated. No protective eyewear, no cooling, or a practitioner who cannot explain contraindications should give you pause. Promises of permanent removal, guaranteed results, or a cure for a skin condition are not credible. High-pressure sales, discounts for booking a big course on the spot, and dismissing your questions about medicines or skin conditions are all reasons to walk away.
Good practice looks like a thorough face-to-face consultation, accurate skin typing, a documented medical history and a patch test before treatment. A trustworthy practitioner is specifically trained and qualified in IPL, insured for it, and happy to show evidence and explain the device, wavelength filter and settings they will use and why. They give protective eyewear to everyone in the room, keep clean and calibrated equipment, and record your settings and reactions each visit. They are honest about whether IPL suits your skin, set realistic expectations of gradual improvement over a course, and will decline or adapt treatment where risk is high rather than simply taking your money. Clear written aftercare, sensible session spacing, and awareness of any local authority registration requirements are further signs of a careful, professional service.
Most people describe IPL as a series of warm flicks or the snap of an elastic band against the skin, along with a bright flash of light seen through the protective goggles. The cooling gel and any chilled tip help take the edge off the heat. Bonier areas, thinner skin and denser or darker hair can feel sharper, while lower-energy settings feel milder. Sensitivity often varies with the area treated and, for some people, with the time of the month. Straight after treatment the skin usually feels hot and tight, much like mild sunburn, easing over the next few hours. Sharp, intense pain during a pulse is not normal and should be mentioned straight away, as it may mean the settings need adjusting.
IPL typically involves little downtime, and most people return to normal activities the same day. Redness and warmth usually settle within a few hours to a couple of days. For skin and pigmentation work, treated spots often darken and then flake over roughly one to two weeks, and some mild swelling can occur around the eyes or on delicate areas. Because a course is usually needed, sessions are commonly spaced a few weeks apart. Sun protection and heat avoidance during this period matter, as the skin is temporarily more reactive. Any blistering, prolonged redness or pigment change should be discussed with your practitioner.
IPL results build gradually rather than appearing overnight, and a course of sessions is usually needed. For hair, several treatments spaced a few weeks apart are typical, aiming for reduction and finer, sparser regrowth rather than guaranteed permanent removal; top-up sessions are often needed over time as some follicles recover, and hormonal changes can prompt new growth. For pigmentation and redness, spots may darken and flake before the skin looks clearer and more even, with maintenance sessions every several months to a year depending on your skin and sun habits. Daily broad-spectrum SPF and sensible sun avoidance protect your results and reduce the chance of pigment returning. Because IPL is tailored to your skin and response, your practitioner should review progress and adjust the plan as you go. Realistic, individual expectations and consistent aftercare give the best long-term outcome.
