TPO Ban in UK: What the New Gel Polish Rules Mean in 2026
If you’ve seen headlines about a “gel nail ban” in the UK, don’t retire your LED lamp just yet. Gel manicures aren’t being banned.
What’s actually changing is one ingredient: TPO.
New rules restricting TPO in cosmetic products came into effect in Great Britain on August 15, 2026, following a similar ban introduced by the European Union in 2025. The change affects some Gel Polish formulas, but it does not mean the end of Gel Polish or your at-home manicure.
So, what does the TPO ban in the UK actually mean, why was TPO banned, and how can you tell if your Gel Polish contains it? Here’s what you need to know.
What is TPO?
TPO stands for Trimethylbenzoyl Diphenylphosphine Oxide. It’s a photoinitiator, an ingredient used in some Gel Polish formulas to help the product cure under UV or LED light.
Photoinitiators are essentially what make gel, well, gel. They absorb light from your curing lamp and trigger the chemical reaction that transforms the liquid formula into the hard, glossy manicure you wear.
TPO became widely used in the nail industry because it is an efficient photoinitiator, particularly when curing highly pigmented Gel Polish shades.
It isn’t the only photoinitiator available, however. Gel formulas can be made using alternatives to TPO, which means removing TPO does not mean removing Gel Polish.
What is the TPO ban in the UK?
TPO has been added to the list of substances prohibited for use in cosmetic products under the UK Cosmetics Regulation in Great Britain.
As of August 15, 2026, cosmetic products containing TPO can no longer be newly placed on the market in Great Britain. An additional transition period allows products already legally placed on the market to remain available until February 14, 2027.
After that off-shelf deadline, TPO-containing cosmetic products can no longer be made available on the GB market.
The rules apply to England, Scotland and Wales. Northern Ireland follows a different regulatory framework, which we’ll get to below.
Is Gel Polish banned in the UK?
No. Gel Polish is not banned in the UK.
Despite some of the headlines surrounding the new rules, the regulation concerns TPO, one ingredient that has historically been used in certain Gel Polish formulations.
TPO-free Gel Polish can still be sold and used. Other compliant photoinitiators can perform the curing function that TPO previously provided, allowing brands to formulate Gel Polish without TPO.
So if you’ve been wondering whether Gel Polish is being banned in the UK, your manicure can stay on the calendar.
When does the UK TPO ban take effect?
There are two dates worth knowing for Great Britain.
August 15, 2026
This is the placing-on-the-market deadline.
From this date, new cosmetic products containing TPO can no longer be placed on the market in Great Britain.
Products that were already legally placed on the market before the deadline may still be available during the transition period.
February 14, 2027
This is the making-available, or off-shelf, deadline.
After February 14, 2027, TPO-containing cosmetics can no longer be made available on the market in Great Britain.
The transition period gives retailers, distributors and professionals time to adapt to the new regulation rather than requiring every existing product to disappear overnight.
What about Northern Ireland?
Northern Ireland is an important exception.
Because cosmetic products in Northern Ireland follow applicable EU cosmetics rules, TPO has already been prohibited there since September 1, 2025, when the European Union ban took effect.
That means the regulatory timeline is not identical across the entire UK.
For England, Scotland and Wales, the new Great Britain deadlines apply. For Northern Ireland, the EU TPO prohibition has already been in effect since September 2025.
Why was TPO banned?
TPO was classified under chemicals legislation as a substance that may be toxic to reproduction, which led to regulatory restrictions on its use in cosmetics.
There is an important distinction here between a substance’s hazard classification and the actual level of exposure from a cosmetic product.
The regulatory classification is based on the inherent hazardous properties of TPO, including evidence involving much higher exposure levels. It does not mean that using a TPO-containing Gel Polish has suddenly been proven to cause reproductive harm.
The UK cosmetics industry has emphasized that cosmetic products containing TPO were subject to safety assessments before being sold and that exposure associated with its use in nail products is very low.
The ban is ultimately a regulatory decision based on TPO’s chemical classification and the availability of alternative photoinitiators.
Why did the EU ban TPO first?
The European Union prohibited TPO in cosmetics beginning September 1, 2025, following its classification as a CMR substance.
CMR stands for carcinogenic, mutagenic or toxic to reproduction. In the case of TPO, the relevant classification relates to potential reproductive toxicity.
Under EU cosmetics legislation, substances receiving certain CMR classifications are generally prohibited from cosmetics unless specific conditions for an exemption are met.
The UK subsequently introduced its own prohibition under the UK Cosmetics Regulation, with the Great Britain transition beginning in August 2026.

Does TPO-free Gel Polish work the same way?
Yes. TPO isn’t the only photoinitiator capable of curing Gel Polish.
Reformulating a Gel Polish without TPO means creating a different photoinitiator system and testing the formula to make sure it still delivers the cure, colour stability and wear expected from the product.
When that reformulation is done properly, your actual manicure routine doesn’t need to change.
You still prep. You still apply your Gel Polish in thin layers. You still cure under an appropriate LED lamp. You still finish with Top Coat.
Different chemistry inside the bottle. Same manicure on your end.
Is TPO the same as TPO-L?
No, and the names make this unnecessarily confusing.
TPO and TPO-L are two different molecules.
TPO is Trimethylbenzoyl Diphenylphosphine Oxide, the ingredient affected by the new regulation.
TPO-L, or Ethyl (2,4,6-trimethylbenzoyl)phenylphosphinate, is a different photoinitiator and should not be assumed to be TPO simply because the names look similar.
When checking an ingredient list, look for the actual ingredient name rather than assuming anything containing the letters TPO is the same substance.
How do I know if my Gel Polish contains TPO?
To check whether your Gel Polish is TPO-free, look for TPO or Trimethylbenzoyl Diphenylphosphine Oxide in the ingredient list on the bottle or packaging, whether it’s a GELCARE product or another brand.
Many GELCARE shades were already formulated with alternatives to TPO before the new European and UK regulations were introduced. Throughout 2025, we worked closely with our laboratories to reformulate the remaining affected products while preserving the colour, application, curing performance and wear of the original formulas.
Since the beginning of 2026, all new GELCARE Gel Polish productions have been TPO-free.
For our UK and EU customers, we’ve taken an additional step. Any shades containing TPO have been removed from the assortment available in these markets until their TPO-free versions are ready. This means that every GELCARE Gel Polish shade currently available to purchase in the UK and EU is already TPO-free.
Our goal is to make the transition as seamless as possible. If you’re shopping GELCARE from the UK or EU, there’s no need to sort through individual shades to determine which ones meet the new requirements. If a shade is available to you, it’s TPO-free.

Should I throw away Gel Polish that contains TPO?
For consumers in Great Britain, the introduction of the ban does not mean that a bottle you already own suddenly became unsafe on August 15, 2026.
The UK transition dates primarily govern when products containing TPO can be placed on and made available on the market.
If you choose to continue using an older Gel Polish that contains TPO, follow the product instructions carefully and avoid getting uncured gel on your skin. Skin contact with uncured gel should be avoided regardless of whether a formula contains TPO.
If you would rather transition your collection now, TPO-free alternatives are already available.
What does the TPO ban mean for nail professionals?
For salons and nail professionals in Great Britain, the transition has a few more practical implications.
New TPO-containing cosmetics can no longer be placed on the GB market after August 15, 2026, and distributors cannot continue making those products available after the February 14, 2027 off-shelf deadline.
Current UK industry guidance indicates that professionals may continue using legally purchased existing TPO-containing stock on clients after the off-shelf deadline, but cannot purchase additional affected products from distributors after that date.
For professionals, now is a good time to check ingredient lists, speak with suppliers and understand which products in your existing collection contain TPO.
Can I still get a Gel Manicure in the UK?
Absolutely.
The TPO ban is not a ban on Gel Polish, gel manicures, LED lamps or nail salons.
It means the industry is moving away from one particular photoinitiator. TPO-free formulas already exist, and brands can formulate Gel Polish using alternative photoinitiator systems.
For the person actually wearing the manicure, the experience can look remarkably familiar.
Choose your colour. Apply. Cure. Repeat.
If you’re building your at-home manicure kit, start with Gel Polish, our LED Nail Lamp or simply go with the GELCARE Starter Kit for everything you need to prep, apply and remove your manicure at home.
What does this mean for your manicure?
For most people using TPO-free Gel Polish, very little changes.
You don’t need a special TPO-free manicure technique. You don’t need to cure your Gel Polish differently simply because the formula does not contain TPO, and you don’t need to give up Gel Polish.
What is changing is what can be formulated and sold on the market.
If you’re shopping for Gel Polish in the UK, check ingredient lists and look for brands that are transparent about their formulations. For GELCARE customers in the UK and EU, every shade currently available to purchase is already TPO-free.
The manicure stays. The ingredient list evolves.

Is Gel Polish banned in the UK?
No. Gel Polish itself is not banned in the UK.
The new rules apply specifically to TPO, a photoinitiator previously used in some Gel Polish formulas. TPO-free Gel Polish can continue to be sold and used, so gel manicures aren’t going anywhere.
When was TPO banned in the UK?
In Great Britain, the TPO transition began on August 15, 2026, when new TPO-containing cosmetics could no longer be placed on the market.
Products already legally placed on the market before that date may remain available during the transition period, with an off-shelf deadline of February 14, 2027.
Why is TPO banned in Gel Polish?
TPO was classified as a substance that may be toxic to reproduction, which led to regulatory restrictions on its use in cosmetics.
The ban relates to TPO’s hazard classification and does not mean that Gel Polish itself is banned. TPO-free formulas can use alternative photoinitiators to achieve the curing performance needed for a gel manicure.
Why is TPO used in Gel Polish?
TPO is a photoinitiator. It absorbs light from a UV or LED lamp and helps trigger the chemical reaction that transforms liquid Gel Polish into a cured coating.
TPO isn’t the only photoinitiator that can perform this function, which is why Gel Polish can be formulated without it.
How can I tell if my Gel Polish contains TPO?
Check the ingredient list on the bottle or packaging for TPO or Trimethylbenzoyl Diphenylphosphine Oxide.
If you’re unsure about a product, particularly an older bottle, check the manufacturer’s ingredient information or contact the brand directly.
Is TPO-L the same as TPO?
No. TPO and TPO-L are different molecules.
TPO-L, or Ethyl (2,4,6-trimethylbenzoyl)phenylphosphinate, is a different photoinitiator and should not be assumed to be TPO simply because the names are similar.
Are GELCARE Gel Polishes TPO-free?
Yes. All new GELCARE Gel Polish productions have been TPO-free since the beginning of 2026, following our transition away from TPO across new production.
For our UK and EU customers, every GELCARE Gel Polish shade currently available to purchase is TPO-free. Any older shades containing TPO have been removed from the assortment available in these markets.
So, if you’re shopping GELCARE from the UK or EU today, you can be confident that every Gel Polish shade available to you is TPO-free.
Can I still get a Gel Manicure in the UK?
Yes. The TPO ban is not a ban on Gel Polish, gel manicures, LED lamps or nail salons.
The regulation affects one ingredient used in certain formulas. TPO-free Gel Polish can continue to be sold and used in the UK.
Does the TPO ban apply to Northern Ireland?
Yes, but under a different timeline. Northern Ireland follows applicable EU cosmetics rules, where TPO has been prohibited in cosmetic products since September 1, 2025.
The August 15, 2026 and February 14, 2027 transition dates apply specifically to Great Britain: England, Scotland and Wales.
