Can you become allergic to gel nails?

"Can you become allergic to gel nails? I keep reading about it."

I get asked this a lot. Clients have seen the headlines, and they know the same ingredients are used in some medical and dental products, so they want to know if they are putting themselves at risk.

We have offered gel polish since the early days and BIAB since it launched. In all that time, as far as I am aware, we have had one client develop an allergy while coming to us. Allergies are real, but they are not simple, and most are not caused by a random reaction to a product.

How a nail allergy happens

Gel polish and builder gel are made from ingredients called acrylates, such as HEMA. In their liquid, uncured form, these ingredients are not meant to touch the skin. When they do, the immune system can become sensitised to them. This often builds up over repeated contact, so someone can have gel nails for years and then react.

Once someone has developed an allergy, it is usually for life. Signs include itching, redness, swelling or blistering around the nails or on the fingertips, and sometimes the nail lifting away from the nail bed. Because these ingredients can travel on the hands, a reaction can also appear on the face, eyelids or neck.

Why it matters beyond nails

The same family of ingredients is used in white dental fillings, bone cement used in joint replacements, and some medical adhesives and devices. An allergy picked up from nail products can affect future dental and medical treatment, which is why dermatologists take it seriously.

In a UK audit of nearly 5,000 patients referred to dermatology clinics for patch testing, 2.4% reacted to at least one of these ingredients, and most of those cases were linked to nail enhancements or nail and lash glue (British Association of Dermatologists, 2018).

What causes most nail allergies

Many, not all, nail allergies come down to the product reaching the skin before it is properly cured. Here are the most common causes:

  • Poor quality or unapproved products. Cheap gels bought online may not meet the rules where you live, may not list their ingredients properly, and may not cure fully under any lamp.
  • Product touching the skin. Rushed or sloppy application can leave gel on the skin around the nail, where it sits uncured.
  • Under curing. This is the big one. Gel can look cured when it is not. Each gel is made to cure under a specific type of lamp, for a set time. Use the wrong lamp, or cut the time short, and some of the product stays uncured and can reach the skin.
  • Broken skin around the nail. Forcing the skin under the free edge or the cuticle back can break the skin's barrier and give the product a way in.
  • An over filed nail plate. A healthy nail plate gives a level of protection. If it has been filed too thin, the product can get through to the nail bed. This is why we do not recommend repeated full removal and reapplication. Every removal causes some damage to the nail plate, so infills are much safer.

Does cured gel cause a reaction?

Gel never cures 100%, but properly cured gel locks the remaining ingredients inside it, so it is very unlikely to cause a reaction. The risk comes from gel that is under cured, which can release those ingredients onto the skin. That is why the lamp, the curing time and the quality of the product all matter.

The perfect storm

Our one client who developed an allergy shows how many things can come together. She was very stressed, going through a break up, and had some immune system issues. She had also disrupted the skin under her free edge by forcing it back. She was the perfect storm for an allergy. Sadly, we have not been able to get her back on gel polish since.

Allergies are rarely down to one thing. They are usually a combination of the product, the application and the person.

How to keep the risk low

  • Choose a qualified nail professional who uses respected, quality brands.
  • Make sure the lamp matches the gel system being used.
  • Do not pick, peel or force off your gel or BIAB.
  • Leave the skin around your nails alone, and do not force the cuticle or the skin under the free edge back.
  • Choose infills over repeated full removal where you can.
  • Avoid home gel kits unless you are trained, as product on the skin and under curing are much more likely.
  • Tell your nail tech straight away about any itching, redness or swelling.

Questions to ask your nail tech

  • Which brand do you use, and is it a professional system?
  • Do you use the lamp made for that gel?
  • How do you make sure no product touches my skin?
  • Do you offer infills, or full removal every time?
  • How do you remove gel or BIAB without damaging my nails?

For nail professionals

Nail techs are at higher risk than clients, because they handle uncured product every day. Keep product off your own skin, avoid touching dust and wipes, and use nitrile gloves, changing them often, as many glove types let these ingredients through. Use the lamp your brand recommends, follow the curing times, and keep product away from the client's skin.

Consultation line: "The risk is very low. Allergies usually happen when uncured product reaches the skin, so I use a professional system with the lamp it is made for, keep product off your skin, and we do infills to protect your natural nail."

FAQ wording: "Can I become allergic to gel nails? It is possible but uncommon. Most reactions happen when uncured product touches the skin. We use professional products cured under the matching lamp, keep product off the skin and recommend infills over full removal to protect your nails."

If a client shows signs of a reaction, stop using gel on them and suggest they see a doctor. These ingredients are not always included in standard allergy tests, so they may need to ask about acrylate patch testing.
