The U.K. cosmetic safety regulator enacts binding restrictions prohibiting high-concentration HEMA and Di-HEMA chemicals in consumer nail products following rising clinical rates of permanent contact allergies.

LONDON, UK — The United Kingdom Health and Safety Executive (HSE) and the Office for Product Safety and Standards enacted binding cosmetic product restrictions on Tuesday, prohibiting the sale of over-the-counter home gel nail kits containing elevated concentrations of acrylate monomers.
The regulatory directive targets 2-hydroxyethyl methacrylate (HEMA) and Di-HEMA trimethylhexyl dicarbamate, reactive monomer chemicals commonly used in UV-cured gel polish to create durable, high-gloss finishes.
Dermatological studies conducted by the British Association of Dermatologists revealed a sharp surge in severe contact allergic dermatitis, onycholysis (nail detachment), and lifelong chemical sensitization among home consumers and salon technicians who improperly cure gel polish under weak UV lamps.
Under the new statutory regulations, gel nail products containing HEMA concentrations above 1% are restricted exclusively to licensed, certified salon professionals who possess verified equipment to achieve full chemical polymer curing.
Retailers and e-commerce platforms have been given a 60-day inventory transition period to remove non-compliant home manicure kits from consumer distribution channels across England, Scotland, and Wales.
Public health authorities advised consumers experiencing tingling, blistering, or nailbed inflammation to discontinue gel manicures immediately, noting that acrylate allergies can cause cross-sensitivities impacting future dental fillings and orthopedic surgical adhesives.
