The UK’s gel nail ban began on Saturday, August 15, with a rule stopping manufacturers and importers from placing new cosmetic products containing TPO on the market. Gel manicures themselves have not been outlawed, and nail technicians can keep using TPO-containing products they already own until their bottles are finished.
Office for Product Safety and Standards
The Office for Product Safety and Standards introduced the restriction after animal studies linked high exposure to TPO with reproductive toxicity and impaired fertility. TPO, short for trimethylbenzoyl diphenylphosphine oxide, is a photoinitiator used to absorb ultraviolet or LED light from curing lamps and harden liquid gel.
The chemical has been reclassified as a Category 1B reproductive toxicant. Whitehall has structured the change as a phased withdrawal, not an immediate removal of every product already in circulation.
August 15, 2026
August 15, 2026 is the hard stop for manufacturers and importers placing new TPO-containing batches on the market. Distributors then have until February 14, 2027 to sell off existing stock. From the following day, sale or commercial distribution of TPO-containing polishes becomes illegal across England, Scotland and Wales.
Northern Ireland has already been operating under TPO-free rules because it follows European Union cosmetic rules under the Windsor Framework. The European Union enforced its own ban on TPO on September 1, 2025, which left Great Britain on a different timetable until this week.
Townhouse and Fresha
Juanita Huber-Millet, founder and creative director of Townhouse, said the salon had spent the past year moving to TPO-free formulations and described the weekend deadline as “business as normal.” That shift means some chains are already working with products that meet the new rule before the final 2026 market deadline arrives.
Danielle Louise, a beauty expert on Fresha, said regular customers do not need to cancel appointments or assume their service has become unsafe. She said, “If you regularly get gel nails, there’s no reason to cancel your appointments or worry that something has suddenly become unsafe.”
She added: “The vast majority of professional salons use trusted brands that keep up to date with cosmetic regulations, and many manufacturers have already introduced reformulated products well ahead of the deadline.” For readers, the practical effect is immediate on supply, not on the service itself: new TPO-based stock leaves the market now, while existing bottles can still be used for months before the final sale deadline closes the transition.
Danielle Louise also said: “These kinds of updates happen more often than people realise. As new scientific evidence becomes available, regulations are reviewed and brands adapt their formulas. It’s one of the ways the beauty industry continues to raise standards.” The open question is how much TPO-containing stock still sits in salons before February 14, 2027.
