Something changed. Your gel manicures used to be fine. No issues, no irritation, nothing. Then one appointment your cuticles started itching. The skin around your nails went red. Maybe it swelled slightly, or you noticed tiny blisters forming near the nail fold.
You’re not imagining it. And you’re not the only one.
Gel nail allergies are more common than most people realise, and they’re almost always caused by a single ingredient that most salons still use. Here’s what’s actually happening, what HEMA is, why it matters, and what you can do about it.
The ingredient responsible in most cases is called HEMA, which stands for hydroxyethyl methacrylate. It’s a monomer used in gel polish to help the product bond to your natural nail. It works, and it’s been standard in gel products for years.
The problem is that HEMA can penetrate the skin barrier, especially if it touches the cuticle area or surrounding skin during application. Your immune system registers it, logs it, and after enough exposure decides to fight it. That process is called sensitisation, and once it happens, it doesn’t reverse.
This isn’t an overnight thing. Most people get gel manicures for months or even years before a reaction appears. Then seemingly out of nowhere, the itching starts. The timing is what makes it so confusing, because from your perspective nothing changed, you went to the same salon and had the same service, but underneath the surface your immune system had been quietly logging every exposure until it finally crossed a threshold and decided to react.
Gel nail allergies don’t always look dramatic. Sometimes it’s subtle enough that you brush it off as dry skin or a minor irritation. But the pattern is consistent.
Itching around the cuticle area, sometimes within hours of the appointment, sometimes a day or two later. Redness along the nail fold or the skin immediately surrounding the nail. Small fluid-filled blisters near the cuticle, which can look similar to eczema. Peeling or flaking skin around the fingers. In more serious cases, the nail itself can start to lift or separate from the nail bed.
If you’re getting these symptoms after gel manicures and they clear up between appointments, that’s your answer. It’s the product, not your skin.
One thing that catches people off guard is that the reaction can spread beyond the fingers. Some people experience contact dermatitis on their face, neck, or eyelids because they’ve touched those areas with freshly manicured nails before the product is fully cured. This sounds extreme, but trace amounts of uncured monomer on the nail surface are enough to trigger a reaction on sensitised skin elsewhere on the body.
Gel nail allergies aren’t new, but awareness has exploded recently. The Guardian published a detailed piece on gel manicure safety that reached a mainstream audience. Social media is full of people sharing their experiences. Dermatologists are speaking publicly about the risks of HEMA exposure.
Part of this is simply more people getting gel manicures than ever before. More exposure across a larger population means more reactions showing up. Part of it is also the rise of at-home gel kits, which significantly increase the chance of product touching skin because application without professional training is less precise. When gel polish floods onto the cuticle during a DIY session and gets cured onto the skin rather than the nail, that’s direct HEMA contact with living tissue, which is exactly how sensitisation develops fastest.
The concern is legitimate. Not a trend. Not a scare. But it’s also not a reason to stop getting your nails done altogether, because the ingredient causing the problem has a straightforward solution: avoid it. Use products that don’t contain it. That’s what HEMA-free means, and it’s what a growing number of salons and professional brands have switched to in the last few years as awareness has caught up with the science.
HEMA-free means the gel product contains zero hydroxyethyl methacrylate. Not reduced. Not trace amounts. None.
This matters because some products marketed as “low-HEMA” still contain enough of the ingredient to trigger reactions in sensitised individuals. The only way to properly avoid it is to use products that have removed it entirely.
HEMA-free gels use alternative monomers that achieve the same bonding and durability without the sensitisation risk. The technology has caught up to the point where HEMA-free products perform just as well as traditional formulas. There’s no trade-off in quality or longevity.
At Aesthete Beauty, every gel product used is HEMA-free and TPO-free. That includes gel polish, BIAB builder gel, and all overlay products. TPO is another ingredient that can cause sensitivity, and removing both means the risk of developing a reaction from products used in this salon is as low as it can realistically be.
If you’ve had a reaction, or you want to avoid one, here’s what to ask before your next appointment.
Start with the obvious one: are the gel products HEMA-free? Not “low-HEMA”. Not “hypoallergenic”. Specifically HEMA-free. A salon that uses HEMA-free products will know the answer immediately because they made a deliberate choice to stock them, and if they stumble over the question or aren’t sure, that’s telling.
Find out what brand they use. You can look it up yourself afterwards to verify the claim. Reputable HEMA-free brands include Luxio, Lecente, The Gel Bottle (their BIAB line), and Halo. Can’t name the brand? Red flag.
Worth asking about TPO as well. It’s less well known than HEMA but it’s another common sensitiser in UV-cured products, and products that are both HEMA-free and TPO-free cover the two main risk factors for allergic reactions to gel nails.
If you’ve already been sensitised to HEMA, switching to a HEMA-free salon should resolve the symptoms. Your immune system reacts to the specific ingredient, not to gel products in general. Remove the ingredient and the reaction stops, though it may take a couple of weeks for existing irritation to fully calm down.
This comes up constantly, and understandably. Pregnancy changes how your body reacts to things, and the last thing you want is to develop a sensitivity while pregnant.
The products used at Aesthete Beauty are HEMA-free and TPO-free with no strong chemical fumes during application. There are no known risks from HEMA-free gel products during pregnancy or breastfeeding, and many of our clients continue their regular nail appointments throughout their pregnancies without any issues.
If you’re pregnant and haven’t had gel nails before, consider a patch test first. It takes ten minutes and gives you peace of mind before committing to a full appointment. If you’ve been getting gels for years without a reaction, continuing with HEMA-free products is straightforward.
The one thing to be aware of is that hormone changes, particularly in the third trimester, can sometimes affect how well gel products adhere. This isn’t a safety issue. It just means the product might not last quite as long as it normally would. Your tech can adjust the preparation to account for this.
Every gel product at Aesthete Beauty is HEMA-free and TPO-free. This wasn’t a marketing decision. It was a practical one based on seeing enough clients come in with reactions from products used elsewhere and knowing there were better alternatives available.
Radina has over 11 years of experience in the nail industry and specifically chose to use products that minimise the risk of sensitisation. The brands stocked are professional-grade, perform identically to traditional formulas, and are used on every single client regardless of whether they’ve had a reaction before.
If you come in with existing gel allergy symptoms from another salon, the first appointment is about assessing the damage, removing any remaining product safely, and letting your nails recover before applying anything new. Rushing back into gel on compromised skin makes things worse, and that’s not something that happens here.
Clients who’ve switched to Aesthete Beauty specifically because of gel allergies often say the difference is immediate. No itching after the appointment. No redness the next morning. Just clean, comfortable nails that look exactly the way gel manicures are supposed to look, without the anxiety of waiting to see whether a reaction shows up.
Gel polish at Aesthete Beauty starts from £43. BIAB from £49. Both HEMA-free, both TPO-free. Book online any time or call 01382 217888.
Should I use HEMA-free gel polish?
If you’ve had any reaction to gel nails, yes. If you haven’t, HEMA-free products reduce the risk of developing one in the future. There’s no downside to using HEMA-free gel. The products perform identically and cost the same to the client.
Do all salons use HEMA-free gel?
No. Many salons still use traditional gel products containing HEMA because they’re cheaper to buy wholesale. Always ask before booking. A salon that uses HEMA-free products will tell you upfront because they know it’s a selling point.
Can gel nails cause onycholysis?
Onycholysis is when the nail separates from the nail bed. It can happen as part of a severe allergic reaction to gel products, but it’s rare and usually only occurs after repeated exposure to an allergen without treatment. If your nails are lifting, see a dermatologist and stop using the product causing the reaction.
What’s the difference between HEMA-free and hypoallergenic?
Hypoallergenic means “less likely to cause a reaction”, which is vague and unregulated. HEMA-free means the product contains zero HEMA. One is a marketing term. The other is a specific, verifiable claim about ingredients.
Can I develop a HEMA allergy at any age?
Yes. Sensitisation can happen at any point after repeated exposure. People who’ve had gel manicures for ten years without issues can suddenly develop a reaction. It’s cumulative, not age-dependent.
How do I know if I’m allergic to HEMA or something else?
A dermatologist can run patch testing for methacrylate allergies. This involves applying small amounts of specific chemicals to your skin under controlled conditions. It’s the only definitive way to identify exactly what’s causing the reaction.
Will my nails recover after a gel allergy?
Yes. Once the offending product is removed and you switch to HEMA-free alternatives or take a break from gel altogether, the skin heals within a few weeks. Nail damage from lifting or peeling grows out over two to three months. Your nails aren’t permanently damaged.
Is BIAB also HEMA-free?
At Aesthete Beauty, yes. The BIAB builder gel used is HEMA-free and TPO-free. This isn’t the case at every salon, so if you’re getting BIAB elsewhere, ask about the specific product being used.
If you’ve been dealing with irritation after gel manicures, or you’d rather avoid the risk entirely, book at a salon that’s already made the switch. Every gel product at Aesthete Beauty is HEMA-free and TPO-free, and has been for years.
