Acrylate Allergy and Gel Polish Manicure - Interview, Consent, Documentation [2026]

A client has been coming in for gel polish for years, and suddenly after a treatment there is itching, redness around the nails, or the plate starts lifting. Allergy to acrylates, the ingredients of gel polishes and gels, is a problem the nail industry talks about more and more loudly - and for a salon it means not only a difficult conversation with the client, but also questions about liability and documentation. This article explains what acrylates are, how to reduce the risk of sensitization, what to record in the client card, and how to react when a client reports symptoms after a treatment. The general rules of liability are covered in our article on post-treatment allergy and salon liability.

What acrylates are and why they sensitize

Acrylates and methacrylates are a group of chemical compounds that harden under a UV/LED lamp - gel polish, gel and acrygel systems are all based on them. The ones most often mentioned in the context of allergies are HEMA and di-HEMA, present in many bases, top coats and colours. Sensitization usually develops through contact of uncured product with the skin - when product floods the cuticles, when a freshly painted plate is touched, or when the stylist works without gloves.

Important legal context: EU rules have restricted the use of HEMA and di-HEMA in nail products - such products are intended for professional use only and must carry appropriate warnings on the label. That shows how seriously the regulator treats the risk of sensitization, and it is also the argument why unlabelled products "from the internet" should never reach your station.

What an allergic reaction after gel polish looks like

• Changes around the nails: itching, redness, small blisters, peeling skin on the nail folds.
• Changes on the plate: the nail lifting from the bed (onycholysis), soreness, hypersensitive fingertips.
• Symptoms beyond the hands: changes on the eyelids or face, where the client transfers trace amounts of product by touching her skin.
• In the stylist: chronic changes on the fingertips and hands - occupational allergy is a real risk when working daily without nitrile gloves.

The diagnosis is made by a doctor, usually a dermatologist or allergist, based on patch testing. Your role is not to diagnose, but to run a reliable pre-treatment interview, work with a technique that keeps product off the skin, and keep documentation showing you exercised due care.

What you do before the treatment - interview and consent

The salon's basic tool is the pre-treatment interview with the client. For nail styling, ask directly about previous reactions to gel polish, gel, false lashes or plasters, about skin conditions, and about visible changes around the nails. You record the answers in the client card with a date and signature - months later, that document will be the only proof of what you established before the treatment.

An interview you did not write down does not exist for the inspector, the insurer or the court. An entry in the card with the client's signature is one minute of work that can win the whole case in a dispute.

If the client reports previous reactions, or you see changes on the skin or plate, you have three honest options: refuse the treatment and suggest seeing a doctor, use products without the most sensitizing ingredients (if you have them and the client understands the limitations), or postpone the visit until the changes are clarified. Each of these decisions goes into the card with your reasoning - a refusal is also an act of due care.

Working technique that reduces the risk

• Zero product-skin contact: thin layers, a margin from the folds and cuticles, immediate clean-up of flooding before curing.
• Full curing: a lamp with power and timing matched to the product, following the manufacturer's recommendations - undercured product is the main source of allergen contact.
• Nitrile gloves for the stylist: they protect you from occupational allergy, which can end a career in this industry.
• Legally labelled products: a full label, INCI ingredient list, professional-use marking. Safety data sheets and chemical storage rules are covered in our article on SDS sheets in the salon.

A client reports symptoms after the treatment - reaction plan

How you react in the first day determines both the client's health and the salon's position in a possible dispute. The table below organizes the steps.

Situation	What you do	What you record
The client calls: itching and redness after the treatment	Advise seeing a doctor, offer free removal of the styling, do not diagnose and do not downplay	Date and content of the report, your advice, what you agreed with the client
The client comes in to have the styling removed	Remove the product gently, without aggressive filing, document the condition of the plate	Description of the nails and skin, actions taken, advice given
The client files a complaint or demands a refund	Accept the complaint in writing and handle it as described in our article on beauty service complaints	Complaint record, copies of the client card and interview, a reasoned response
You suspect a defect in a specific product	Secure the packaging with the batch number, stop using the product, contact the distributor	Product name, batch number, dates of use, correspondence with the supplier

What about a permanently sensitized client

A confirmed acrylate allergy usually means the end of classic gel polish and gel for that client - each exposure intensifies the reactions. Record the allergy in the card (with the client's consent, as this is health data) and flag it so no stylist in the salon performs the treatment by accident. You can offer alternatives without lamp curing, such as a classic manicure with regular polish, while being honest that the safety decision belongs to the doctor, not the salon.

Frequently Asked Questions

Is a patch test required before a gel polish manicure, like before brow henna?

For nail styling the standard is the interview and client card, not a patch test in the form known from brow and lash treatments. Nail products cure under a lamp, so a skin test does not reproduce the treatment. What matters is asking about previous reactions, a technique keeping product off the skin, and full curing.

Is the salon liable if a client became sensitized despite a correct treatment?

An allergy can develop despite full due care - its mere occurrence does not decide the salon's fault. Liability turns on whether you ran the interview, worked according to good practice and the manufacturer's instructions, and can document it. Without a client card and interview you are in a losing position in a dispute, even with flawless technique.

Can I use products containing HEMA?

Nail products containing HEMA and di-HEMA are permitted for professional use, with the appropriate labelling. As a professional you can use them, working with a no-skin-contact technique. Avoid products without a full label and ingredient list - you do not know what you are applying and cannot defend yourself if something goes wrong.

How do I protect myself as a stylist from occupational allergy?

Work in nitrile gloves (latex does not protect against acrylates effectively), change them when soiled with product, do not touch uncured layers, and keep your station ventilated. Consult a dermatologist quickly about the first symptoms on your fingertips - the sooner you stop the exposure, the better the chance of continuing in the profession.
