New UK regulations on gel nail polish ingredients came into force on Saturday, August 15, targeting the photoinitiator trimethylbenzoyl diphenylphosphine oxide (TPO), which is found in some gel nail polishes. The rules mean certain cosmetic ingredients can no longer be used in new products placed on the market.
TPO has already been banned in the EU since September 1, 2025. Earlier this month, restrictions also took effect on the UV filter 4-MBC used in some cosmetic products, alongside updated limits for the fragrance ingredient Methyl Salicylate.
Salons Update Products
These new rules have forced UK-based salons and beauty brands to update some of the products they use. However, beauty experts insist that clients visiting reputable salons are unlikely to notice any difference to their treatments.
Danielle Louise, Beauty Expert on Fresha, the world's leading beauty and wellness booking platform, says the new rules are simply part of how the industry continues to improve product safety.
She said: "If you regularly get gel nails, there's no reason to cancel your appointments or worry that something has suddenly become unsafe. 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."
No Visible Changes Expected
Danielle says consumers are unlikely to notice major changes, but the new rules highlight the importance of where you have your nails done. She advises choosing a reputable salon that uses recognised professional products and follows good hygiene practices.
She added: "One of the best things you can do is choose a reputable salon that uses recognised professional products and follows good hygiene practices. If you're ever unsure about the products being used, don't be afraid to ask. A professional nail technician should be happy to explain which brands they use and answer any questions you have."
Danielle also notes there will be no noticeable difference to the look or longevity of gel manicures, with the same colours, finishes and treatment options likely to remain available. Anyone with allergies, sensitive skin or previous reactions to beauty products should inform their nail technician before treatment.
The beauty expert added: "Professional salons want clients to feel confident about the treatments they're receiving. These regulatory changes are ultimately about ensuring products continue to meet the latest safety standards, not about making beauty treatments less accessible."
