How to Avoid Gel Polish Allergies in Your Salon

Gel polish allergies are a genuine occupational health concern for nail technicians, and a growing issue for frequent gel polish users. Understanding what causes them, how to prevent them, and what to do if a client or technician develops a reaction is essential knowledge for any professional salon. Here's what you need to know.

What Causes Gel Polish Allergies?

The most common cause of gel polish allergies is sensitisation to HEMA (2-Hydroxyethyl Methacrylate) — a monomer found in many traditional gel polish formulations. Sensitisation occurs when uncured gel polish makes repeated contact with the skin, particularly around the cuticle and nail folds.

The critical point is that cured gel polish does not cause sensitisation. It's the liquid, uncured gel that contains the sensitising monomers. Once properly cured under an LED or UV lamp, the gel is fully polymerised and the monomers are no longer active. The risk comes from skin contact with the product before and during application.

Why Undercuring Is a Major Risk

Undercured gel polish — product that hasn't been fully exposed to the correct amount of light — leaves unreacted monomers in the surface of the gel even after the client leaves the salon. These monomers can then come into skin contact during daily activities, causing sensitisation over time without the client or technician being aware of the source.

This is why professional-grade lamps and correct cure times are a health issue as well as a quality issue. Underinvesting in lamp quality doesn't just affect longevity — it increases sensitisation risk for both clients and technicians.

What Is HEMA-Free Gel Polish?

In response to growing awareness of HEMA sensitisation, several professional gel polish brands — including Gelish — now offer HEMA-free formulations. These products use alternative monomers that deliver the same professional performance with a significantly reduced sensitisation risk profile.

The Gelish gel polish range is HEMA-free and TPO-free, making it one of the safer choices for professional salon use. This doesn't mean there is zero risk — skin contact with any uncured gel should always be avoided — but the risk of HEMA sensitisation is eliminated by choosing a HEMA-free formula.

Practical Prevention in the Salon

• Never apply gel to the skin — keep product off the cuticle, nail folds and surrounding skin at all times. If gel touches the skin, remove it with an orangewood stick before curing.
• Cure properly every time — ensure every coat is fully cured under a professional LED lamp. Never skip or shorten cure times.
• Use HEMA-free gel polish — Gelish gel polish is HEMA-free and TPO-free, significantly reducing sensitisation risk for both clients and technicians.
• Wear nitrile gloves — nail technicians who apply gel polish repeatedly throughout the day should wear nitrile gloves to prevent occupational skin exposure.
• Ventilate your workspace — ensure adequate ventilation in your salon treatment area to reduce fume exposure.
• Use dust extraction — when filing or removing gel, use a nail dust extractor to prevent inhalation of gel dust.
• Don't use gel products on broken or damaged skin — skin that is cut, inflamed or compromised is more susceptible to sensitisation.

Signs of a Gel Polish Allergy

Common symptoms of gel polish sensitisation include:

• Itching, redness or swelling around the nail area during or after gel application
• Blistering or flaking skin around the cuticle or nail folds
• Burning sensation during LED curing
• Reactions appearing on other areas of the body where the person has touched their hands (e.g. eyelids, neck)
• Symptoms that worsen with each exposure and improve when avoiding gel products

If a client presents with any of these symptoms, do not continue with gel services and advise them to consult a GP or dermatologist. Continuing to use gel products on a sensitised individual can cause increasingly severe reactions.

Frequently Asked Questions

Can you become allergic to gel polish suddenly?
Yes — sensitisation is cumulative. You may use gel polish for years without issue, and then develop a reaction. Once sensitised, even small exposures can trigger significant reactions.

Is HEMA-free gel polish completely safe?
HEMA-free gel polish eliminates the risk of HEMA sensitisation but still requires correct application technique (no skin contact with uncured product) and proper curing. All uncured gel polishes should be kept off the skin regardless of the formulation.

Can clients with existing gel polish allergies switch to a different brand?
Clients who have developed a sensitisation to HEMA should seek medical advice before continuing any gel nail services. Switching to a HEMA-free formulation may be an option, but this should be confirmed by a dermatologist.

Are nail technicians at higher risk of gel polish allergies than clients?
Yes — due to the frequency and duration of their exposure. Nail technicians who apply gel polish multiple times per day are at significantly higher occupational risk than clients who have gel applied every 2–3 weeks.
