Is Gel Polish Banned in the UK? What the TPO Ban Actually Means for Nail Technicians

If you have recently seen headlines saying that gel nails have been banned in the UK, you could reasonably assume that gel manicures themselves are disappearing from salons. That is not what the regulation says.

What Is TPO and Why It Has Been Used in Nail Products

Trimethylbenzoyl Diphenylphosphine Oxide, commonly abbreviated to TPO, is a photoinitiator. Its function is to react when exposed to UV or LED light, triggering the curing process that hardens gel product on the nail. This is what allows a gel manicure to set quickly under a lamp rather than air-drying over time.

TPO has been valued in nail formulations for producing a durable, glossy finish with efficient curing, particularly under LED lamps. It is not the only photoinitiator available to manufacturers, but it has been a commonly used one across a range of gel and builder products.

The Regulation Concerns TPO, Not Gel Technology Itself

This distinction sits at the centre of the entire issue. TPO is one specific ingredient. Gel nail systems, as a category of professional nail technology, are not defined by that single ingredient. A gel or builder product can be reformulated to use a different, permitted photoinitiator and continue to function as a UV or LED-curable system.

Restricting one ingredient is not the same as prohibiting an entire professional service.

Why “Gel Nail Ban” Headlines Are Misleading

A headline written for a general consumer audience often compresses a technical regulatory change into language that implies something far broader than what the regulation actually covers. “Gel nail ban” suggests the service itself has been prohibited. The regulation in question restricts a named chemical ingredient in cosmetic products. These are not the same statement, and the difference matters considerably to a professional trying to understand her legal obligations.

The European Union Regulatory Position

The European Union stopped allowing TPO in cosmetic products from 1 September 2025. This came from Commission Regulation (EU) 2025/877, made under the EU’s Cosmetics Regulation. The reason for the change was that TPO had been reclassified as a Category 1B reproductive toxicant under separate chemicals safety law.

From that date, nail technicians in the EU could no longer use products containing TPO on clients. This applied even to stock bought legally before the rule changed. No exemption was granted for the professional nail sector, so there was no grace period allowing technicians to use up existing stock.

The Great Britain Regulatory Position

Great Britain means England, Scotland and Wales. Great Britain has its own separate rules, not the same as the EU’s. TPO was added to the GB list of restricted chemicals after being reclassified in the same way as in the EU. This then triggered the ban process under GB cosmetics law.

The relevant law is called SI 2026/23, short for the Cosmetic Products Regulation (EC) No 1223/2009 (Restriction of Chemical Substances) (Amendment and Transitional Provisions) Regulations 2026. It was adopted in January 2026. According to this legislation, TPO was added to the list of banned cosmetic ingredients in Great Britain, alongside several other substances.

Great Britain has two important dates, not one:

These two dates come directly from the Statutory Instrument. There is also a third, practical question: can you keep using stock you already own after these dates? The Cosmetic, Toiletry and Perfumery Association (CTPA), the UK’s cosmetics trade body, has answered this. Working together with Trading Standards, the CTPA says yes: you can keep using stock you already legally own on clients after 14 February 2027, until you run out of it. This is guidance from the trade body, not wording written directly into the law itself, so it is worth checking with your own supplier or trade body too.

Northern Ireland Is Not the Same as Great Britain

This is one of the most commonly overlooked distinctions in current reporting. Northern Ireland continues to follow European Union cosmetics legislation, under the arrangements set out in the Windsor Framework. This means Northern Ireland has been subject to the EU’s TPO prohibition since 1 September 2025, considerably earlier than the Great Britain timetable set out above.

A nail technician working in Northern Ireland is not on the same legal timetable as a technician working in England, Scotland or Wales. Treating the whole of the UK as a single regulatory jurisdiction on this issue is inaccurate.

Why the Prohibition Happened: Understanding the Classification

TPO was reclassified as a Category 1B reproductive toxicant. This classification comes from CMR chemicals law, which stands for carcinogenic, mutagenic or toxic for reproduction. It was based on evidence from animal studies.

Here is how the rule works: once a substance gets this classification, it is automatically added to the list of banned cosmetic ingredients. There is one exception, if a specific request for an exemption is made and approved after a safety review. No such exemption was requested for TPO, so the ban went ahead.

It helps to separate three different things here. First, a substance getting a hazard classification. Second, the legal ban that classification triggers. Third, the actual level of risk to a real client sitting in a salon chair. A hazard classification tells you what a substance can do under laboratory test conditions. It does not, by itself, tell you the precise risk of a specific, real-world exposure.

What the Earlier Safety Opinion Actually Said

Before TPO was reclassified, an EU scientific body called the Scientific Committee on Consumer Safety (SCCS) looked at TPO separately. In an opinion numbered SCCS/1558/15, the SCCS said TPO was safe when used as a professional nail modelling product, at a maximum strength of 5%. The same opinion also said TPO should be treated as a moderate skin sensitiser, meaning it can cause an allergic-type reaction in some people.

This older opinion does not disprove the newer ban, and it is not being hidden or contradicted either. The SCCS wrote that opinion when TPO carried a different, lower classification. Once TPO was reclassified as CMR Category 1B, the law works differently: the classification itself triggers an automatic ban, regardless of what an earlier concentration-based safety opinion said. The two findings sit in two different legal boxes; they are not competing with each other.

According to the CTPA, the amount of TPO actually used in nail products sits far below the level connected to any effect on fertility in the studies behind the classification. This is one reason professional bodies describe the change as a cautious, classification-driven step, rather than proof of harm from typical salon-level exposure.

The Regulation Did Not Ban Gel Nails

A nail system is not defined by one photoinitiator. Manufacturers can, and many already have, reformulate products using permitted alternative photoinitiators while keeping the same UV or LED-curable gel technology intact.

TPO being prohibited does not mean gel technology has been prohibited. Gel manicures, BIAB, builder gel and hard gel systems remain legal professional services in the UK, provided the specific products used comply with current cosmetics regulation.

What Should Nail Technicians Actually Do?

This is general professional guidance, not legal advice. Every business is responsible for ensuring the specific products it uses comply with applicable cosmetics regulation in its own jurisdiction.

TPO-Free Does Not Mean Risk-Free

Removing TPO from a formulation does not remove every other consideration that applies to UV or LED-curable professional products. A TPO-free product still requires the same professional attention as any other gel or builder system.

This is not a suggestion that alternative photoinitiators carry hidden dangers. There is no evidence presented here to support that claim, and none is being implied. The point is narrower and more practical: compliance with one ingredient restriction is not a replacement for correct professional practice as a whole.

Why Media Headlines Create Confusion

Phrases circulating in current coverage include “gel nail ban”, “gel polish ban”, “ban in nail salons”, and headlines linking the story directly to fertility concerns. None of these phrases are necessarily dishonest on the part of the publications using them. A headline is written to be read in seconds and to communicate a general sense of a story to a broad consumer audience. That format is simply not well suited to conveying the distinction between a hazard classification, a specific ingredient restriction, and the continued legality of an entire professional service.

The practical result is that many readers, including working nail technicians, come away with an impression considerably broader than what the underlying regulation states. Reading the regulation itself, or a source that explains it accurately, remains the more reliable approach than forming a professional understanding from a headline alone.
