Has the UK Banned Gel Nail Polish? The Truth About New Rules and TPO Chemical Safety

The UK has introduced new restrictions on a chemical used in some gel nail products, but the widely reported “gel nail ban” does not mean gel manicures themselves are being prohibited. The new rules target trimethylbenzoyl diphenylphosphine oxide (TPO), a photoinitiator that helps gel polish harden under UV or LED light, The Independent reported.

The restrictions came into effect on August 15, 2026, preventing manufacturers and suppliers from placing new TPO-containing cosmetic products on the market in Great Britain. However, salons have been given a transition period to use existing stock, with the final deadline for removing TPO-containing products set for February 14, 2027. Burgundy Broken Heart Nail Trend: Chrome Nail Look for Valentine’s Day Mood Board.

Has the UK banned gel nail polish?

No. The UK has not banned gel nail polish or gel manicures as a treatment. Instead, the new regulations prohibit the use of TPO in cosmetic products. TPO is found in some UV- and LED-cured gel formulations, but many gel products are already made without the chemical. Traditional nail polish that dries naturally is not affected by the TPO restriction.

The rules currently apply to England, Scotland and Wales, which together make up Great Britain. Northern Ireland follows a different cosmetics regulatory framework because of its post-Brexit arrangements and continues to follow relevant EU cosmetics legislation. Salmonella Outbreak in UK: 1 Death, 207 Cases Linked to Imported Eggs, UKHSA Says; Check Symptoms and Prevention.

What is TPO and why is it used?

TPO, or trimethylbenzoyl diphenylphosphine oxide, is a photoinitiator. In gel nail products, it helps trigger the chemical reaction that causes the polish to cure when exposed to UV or LED light.

The ingredient is therefore important to the hardening process that gives gel manicures their characteristic durable and glossy finish.

Not every gel polish contains TPO, meaning consumers do not need to stop having gel manicures simply because of the new rules.

Why has TPO been restricted?

The regulatory change follows concerns about TPO's potential reproductive toxicity. The European Union classified the substance as a Category 1B reproductive toxicant, based primarily on evidence from animal studies and high-exposure scenarios.

The EU subsequently prohibited TPO in cosmetic products from September 1, 2025, under its rules governing substances classified as carcinogenic, mutagenic or toxic for reproduction.

The Cosmetic, Toiletry and Perfumery Association (CTPA) has stressed that the regulatory classification reflects the potential hazard of the substance under particular exposure conditions. Caroline Rainsford, the association's director of science, said the quantities used in nail products are substantially lower than levels associated with harmful effects in the relevant studies and that the products are applied to the nail.

The restriction is therefore a precautionary regulatory measure and should not be interpreted as evidence that every previous gel manicure containing TPO caused reproductive harm.

What happens to salons with existing TPO products?

The UK rules have a transition period.

From August 15, 2026, manufacturers and suppliers cannot place new TPO-containing cosmetic products on the Great Britain market. However, products already in the supply chain can continue to be used during the transition period.

Salons can therefore still encounter or use existing TPO-containing stock for the time being. The final deadline is February 14, 2027, after which TPO-containing cosmetic products must no longer be made available for use on the market.

This means the change will be gradual rather than an immediate end to gel manicures.

What will salons use instead?

There are already TPO-free gel formulations available, and many salons have moved towards products that do not contain the restricted ingredient.

The alternatives are designed to provide the same basic function — curing under UV or LED light — without TPO. Industry guidance indicates that salons should check product ingredients and obtain confirmation from suppliers that their stock complies with the new requirements.

For customers, this means gel manicures are expected to remain widely available, although the products used by individual salons may change.

What does the new rule mean for customers?

For most people, the immediate impact is limited. Customers do not need to stop booking gel manicures simply because the TPO restrictions have come into force.

Those who want to avoid TPO can ask their nail technician whether the gel products being used are TPO-free. Checking the product's ingredient information or asking the salon to confirm compliance with the new regulations can also provide clarity.

The main change is taking place behind the scenes as salons and suppliers replace affected products with compliant alternatives.

UK follows the EU on TPO restrictions

The UK action brings Great Britain closer to the EU's position on TPO in cosmetics. The EU prohibition took effect in September 2025, while the corresponding Great Britain restrictions began in August 2026.

The difference in timing has allowed TPO-containing products to remain available in parts of the UK after the EU prohibition, but the Great Britain transition will end in February 2027.

The bottom line

The phrase “UK gel nail ban” is misleading. Gel nail polish and gel manicures have not been outlawed. The new rules specifically target TPO, a chemical used in some gel nail formulations to help them cure under UV or LED light.

New TPO-containing cosmetic products can no longer be placed on the Great Britain market from August 15, 2026, while salons have until February 14, 2027 to complete the transition away from existing TPO stock. TPO-free gel products are already available, so the new rules are expected to change the formulations used in salons rather than bring an end to gel manicures.
