Laser Resurfacing
- Independent guide from The Hair & Beauty Directory
About Laser Resurfacing
Laser resurfacing uses focused light energy to remove or heat the outer layers of skin in a controlled way, prompting the body to shed damaged cells and lay down fresh collagen. It is used to soften fine lines, uneven texture, sun damage, enlarged pores and some scarring, and to improve overall tone and radiance. Treatments range from gentler non-ablative and fractional lasers, which work in tiny columns and leave surrounding skin intact for quicker healing, through to fully ablative carbon dioxide (CO2) and erbium lasers, which resurface more deeply for stronger results but with more downtime. Because a laser is a powerful energy device, results depend heavily on the practitioner choosing the right device, wavelength, depth and settings for your skin. In most cases a course or a single deeper session is planned around your skin type, concerns and how much recovery time you can allow. This is a treatment where candidate suitability really matters, particularly for medium and darker skin tones, so a thorough consultation and honest expectations are as important as the technology itself. It is not a substitute for medical care for skin conditions.
On the day, and after
During the treatment
Your practitioner will cleanse the skin and confirm the plan, settings and expected recovery before starting. Protective eyewear is worn by you and the practitioner, and the treatment room follows laser safety rules. Depending on the device and depth, a numbing cream, cooling or local anaesthetic may be used, and deeper ablative work is sometimes carried out under stronger anaesthesia in a clinical setting. The laser is passed over the treatment area in sections, and you will usually notice a warm, prickling or snapping sensation along with the smell of the device and a cooling airflow. A session can take from around twenty minutes for a small area to over an hour for a full face. Gentler fractional and non-ablative treatments feel milder, while fully ablative resurfacing is more intense and more tightly controlled. Afterwards the skin is soothed and dressed as needed, and you will be given clear written aftercare and, where relevant, follow-up arrangements.
How it feels
During treatment most people feel warmth with a prickling, tingling or rubber-band snapping sensation, eased by numbing cream, cooling air or, for deeper work, local anaesthetic. You may notice the smell of the laser and a cool draught from the device. Afterwards the skin often feels hot, tight and sunburnt, and may sting for a few hours. Gentler lasers feel milder and settle within a day or two, while ablative resurfacing can feel raw, swollen and tender for several days, sometimes with itching as new skin forms. Sensations vary with the device, depth and area treated, and your practitioner should tell you what is normal for your session.
Results and maintenance
Results build gradually as the skin heals and new collagen forms, so the full effect of resurfacing usually appears over weeks to several months rather than straight away. Gentler non-ablative and fractional treatments are often done as a course of sessions to steadily improve tone, texture and fine lines, while a single deeper ablative treatment can give a more pronounced change from one session. How long results last depends on your skin, age and lifestyle, and on how well you protect the result. Daily broad-spectrum SPF, sun avoidance and a good skincare routine are the most important ways to preserve the improvement, as fresh sun damage undoes it. Many people have occasional maintenance or top-up sessions over time. Your practitioner can tailor the intensity, depth and number of sessions to your concerns, your skin type and how much downtime you can accommodate, so the plan should be personal to you.
Before and after your appointment
Before your appointment
Preparation usually starts with a face-to-face consultation and a review of your medical history, skin type and any medicines you take. You will typically be asked to avoid sun exposure, sunbeds and fake tan for several weeks beforehand, as tanned or recently exposed skin raises the risk of burns and pigment changes. Retinoids, exfoliating acids and other active skincare are often paused in the days before, on your practitioner's advice. If you are prone to cold sores, tell your practitioner, as antiviral tablets are commonly prescribed before and after resurfacing near the mouth to prevent a flare. You may be advised to stop or discuss certain medicines and supplements that affect healing. A patch or test area is sometimes carried out, especially for deeper or ablative lasers. Arrange time off and cover for the healing period, and line up gentle, fragrance-free aftercare products in advance. Come to your appointment with clean skin, free of make-up, sunscreen and lotions.
Aftercare
Aftercare is central to a good result and to avoiding complications, so follow your clinic's written instructions closely. Skin is typically red, warm, swollen and sensitive, and with ablative lasers it may weep or crust as it heals. Keep the area clean and moist using the gentle emollient or ointment your practitioner recommends, and avoid picking or peeling any flaking or scabs, which can cause scarring and pigment change. Use only bland, fragrance-free products and pause active ingredients such as retinoids and acids until your skin has settled. Broad-spectrum SPF 50 every day and strict sun avoidance are essential for several weeks to months, because healing skin marks and darkens very easily. Skip make-up, saunas, swimming, heavy exercise and hot environments until your practitioner says it is safe. Continue any prescribed antivirals, and contact your clinic promptly if you notice spreading redness, increasing pain, pus or signs of infection.
Downtime depends on the depth of treatment. Gentle non-ablative and light fractional lasers may cause redness and mild swelling for a few days, with skin that feels rough or sandpapery as it renews. Deeper fractional and fully ablative resurfacing typically involves five to ten days or more of redness, swelling, weeping and crusting before new skin surfaces, and lingering pinkness that can last several weeks to a few months. Many people plan ablative treatments around time away from work and social events. Full collagen remodelling continues quietly for months afterwards, so the final result builds gradually rather than appearing at once.
Safety and medical considerations
Safety essentials
Laser resurfacing is a powerful energy-based treatment, so the practitioner's competence and your suitability matter more than any single device. Choose a practitioner who is properly trained and assessed in laser use, insured for it, and working in an appropriately regulated setting, ideally with medical oversight for deeper ablative work. In Scotland and Wales, clinics providing laser and IPL must be registered with the national regulator, and in parts of England, including London, local authority special treatment licensing may apply, so it is reasonable to ask what registration the clinic holds. Correct device selection, wavelength, depth and settings for your skin type are what prevent burns, scarring and long-lasting pigment changes, which are more likely on medium and darker skin. A proper consultation, test patch where appropriate and clear aftercare should always be part of the process. Never feel rushed into treatment, and avoid deals that skip consultation or suitability checks.
Medical considerations
Share your full medical history at consultation, as several conditions and medicines affect suitability and healing. Recent use of isotretinoin (Roaccutane) is a common reason to postpone resurfacing, typically for a period agreed with your prescriber, because it can impair healing and raise scarring risk. A history of keloid or hypertrophic scarring, active acne, eczema or infection in the area, a tendency to cold sores, and conditions that slow healing such as poorly controlled diabetes all need to be discussed. Laser resurfacing is generally avoided in pregnancy. Medium and darker skin tones carry a higher risk of post-inflammatory hyperpigmentation and need careful device and setting choices, and sometimes preparatory skincare. Some medicines and supplements affect bleeding or photosensitivity and should be reviewed. If you have a diagnosed or changing skin lesion, or any concern about a mole or spot, see your GP or a dermatologist first, as laser is not a treatment for undiagnosed skin conditions.
Patch testing
A skin patch or small test area is sometimes carried out before laser resurfacing, particularly for deeper or ablative devices and for medium to darker skin tones, to see how your skin responds before treating a larger area. More important still is a thorough face-to-face consultation that records your skin type, medical history, medicines, sun exposure and any history of cold sores, keloid scarring or pigmentation problems. These checks are what allow the practitioner to select safe settings and identify anyone who should not be treated. Framed around reducing risk and UK liability, skipping proper suitability assessment leaves both client and practitioner exposed, and an insured practitioner who omits these checks could be found at fault if harm follows. Ask what pre-treatment testing your clinic uses and why.
Knowing a good practitioner
Green flags
Good practice starts with an unhurried consultation, a recorded medical history and honest advice about whether laser resurfacing suits your skin and goals. A reputable practitioner is trained and assessed in laser use, insured for it, and works in a clean, appropriately regulated setting, with medical oversight for deeper treatments. They explain the device, depth and settings chosen for your skin type, discuss realistic results and downtime, and are open about risks such as pigment change and scarring. Expect protective eyewear, laser safety measures, a test patch where appropriate, clear written aftercare and accessible follow-up. Registration with the relevant national regulator or local authority, and membership of a recognised professional register, are reassuring signs.
Red flags
Be cautious if a practitioner cannot explain their laser training, insurance or the device and settings they will use, or if they treat you without a proper consultation and medical history. Pressure to book quickly, heavily discounted deals and no test patch or suitability check are warning signs. It is a concern if darker skin tones are treated with no discussion of pigmentation risk, or if you are offered deep ablative resurfacing in a non-clinical setting with no medical oversight. A reluctance to provide written aftercare, no clear plan for managing complications, unhygienic surroundings, or promises of guaranteed or permanent results should all give you pause. Trust your instincts and walk away if anything feels rushed or unsafe.
Questions to ask
- What are your laser qualifications and how much experience do you have treating skin like mine, including my skin tone?
- Which type of laser and depth are you recommending for my concerns, and why is it the right choice for me?
- Is this clinic registered with the relevant regulator or local authority, and do you carry specific laser insurance?
- What results are realistic for my skin, how many sessions might I need, and how much downtime should I plan for?
- What are the risks for my skin type, including pigment changes and scarring, and how would you manage a complication?
- Will you do a test patch and a full consultation, and what aftercare and follow-up support do you provide?
Frequently asked questions
Is laser resurfacing painful?
Most sessions are manageable with numbing cream, cooling or, for deeper work, local anaesthetic. You will usually feel warmth and a prickling or snapping sensation, and the skin often feels sunburnt for a few hours afterwards. Deeper ablative treatments are more intense and are carried out with stronger pain relief in a clinical setting.
How long does it take to recover?
Recovery depends on the depth. Gentle lasers may cause a few days of redness and roughness, while deeper fractional or ablative resurfacing typically involves five to ten days or more of redness, swelling, weeping and crusting, followed by pinkness that can linger for several weeks to a few months.
Is laser resurfacing safe for darker skin tones?
It can be, but medium and darker skin carries a higher risk of pigment changes such as post-inflammatory hyperpigmentation, so device choice, settings and sometimes preparatory skincare are especially important. Choose a practitioner experienced in treating your skin tone, and expect a careful consultation and often a test patch first.
How many treatments will I need?
This varies. Gentler non-ablative and fractional lasers are often done as a course of several sessions for a gradual improvement, while a single deeper ablative treatment can achieve more in one go but with more downtime. Your practitioner should recommend a plan tailored to your skin and goals at consultation.
Can I wear make-up and go in the sun afterwards?
Not straight away. Make-up is usually paused until the skin has healed, and strict sun avoidance with daily broad-spectrum SPF 50 is essential for several weeks to months, because healing skin marks and darkens very easily. Following this protection is one of the biggest factors in a good, lasting result.
