If you picked up your sunscreen this morning, there’s a reasonable chance it contains an ingredient that will be illegal by summer. The same goes for your gel nails, your shampoo and possibly that anti-ageing serum you bought because the label said ‘nanotechnology’.

From May 2026 in the EU and July 2026 in the UK, a wave of new cosmetics regulations will ban or restrict more than a dozen ingredients classified as carcinogenic, mutagenic or toxic to reproduction. The names are long, the science is dense, but the short version is this: regulators have decided these things should not be touching your skin.

## The sunscreen in your drawer

The most noticeable change will be in sunscreens. A UV filter called 4-MBC (you won’t find it written that plainly on the bottle; look for enzacamene or 4-methylbenzylidene camphor) is being banned outright in the UK. It has been used in sun protection products for decades, but concerns about endocrine disruption and potential genotoxicity mean it is on its way out.

If your sunscreen was bought before July 2026, shops can continue selling it until January 2027. But brands are already reformulating.

## The preservatives hiding in your shampoo

Formaldehyde was banned from cosmetics in 2019. But here’s the part that catches people off guard: ingredients that slowly release formaldehyde were not. They’re called formaldehyde releasers, and they’ve been quietly sitting in shampoos, body washes and liquid soaps for years.

Names to look for: bronopol, DMDM hydantoin, imidazolidinyl urea, diazolidinyl urea and sodium hydroxymethylglycinate. If any of that sounds familiar, it’s because these are [common preservatives](https://richwoman.co/article/unvarnished-truth-harmful-chemicals-going-under-your-skin). The new rules don’t ban them all, but they dramatically lower the threshold for mandatory labelling (from 0.05% to 0.001%), which means far more products will now have to declare what is actually in the bottle.

## Gel nails, hair care and the rest

The bans also reach into places you might not expect. TPO, used in gel nail products and UV-cured cosmetics, is on the list. Dibutyltin compounds (stabilisers found in some hair care and deodorants) are going too. Even silver in its nano form, marketed in premium skincare as a cutting-edge ingredient, is now restricted.

Multi-walled carbon nanotubes (often sold under the umbrella of ‘nanotechnology’ claims) are also being pulled. If you’ve ever paid extra for a product because it promised nano-level skin benefits, it’s worth [checking the ingredients list](https://richwoman.co/article/no-more-guesswork-how-a-chemist-is-helping-women-decode-beauty-labels).

## What this actually means for you

The honest answer is: not much disruption, but some awareness. Most mainstream brands have been reformulating ahead of the deadlines. Products already on shelves get a sell-through period (usually six to twelve months after the ban takes effect). You won’t wake up one morning to find your entire skincare routine is illegal.

But it’s worth knowing what you’re putting on your skin. If a product you’ve used for years quietly contained a formaldehyde releaser, the new labelling rules will make that visible for the first time. And if your sunscreen still lists enzacamene as an active ingredient, it might be time to find a new one.

The regulations aren’t about panic. They’re about the slow, overdue work of making the [things we use every day](https://richwoman.co/article/diy-skincare-boom-signals-shift-to-ingredient-transparency-and-personalised-self-care) a little safer. Which, when you think about it, is exactly what ‘clean beauty’ was supposed to mean all along.

## In case you were wondering…

**Q: Are formaldehyde releasers dangerous in small amounts?**
The risk depends on concentration and how often you’re exposed. At very low levels, most formaldehyde releasers are unlikely to cause harm in a single use. But cosmetics aren’t single-use products. Shampoo, body wash and moisturiser are applied daily, sometimes more than once. Over years, that cumulative exposure adds up. The new regulations reflect growing evidence that even low-level, long-term contact with formaldehyde can sensitise skin and, in some cases, pose broader health risks. The lowered labelling threshold is designed to let you make that judgement for yourself.

**Q: Why are some ingredients only being restricted rather than banned?**
Not every ingredient on the list is equally harmful. Some (like hexyl salicylate, a common fragrance compound) are being restricted to lower concentrations rather than removed entirely. This usually means the science shows risk at higher levels but not at trace amounts. Regulators weigh the available alternatives, the severity of the concern and whether reformulation is practical. A restriction is essentially a compromise: you can still use it, but less of it, and with clearer labelling.

**Q: How do I check whether my products contain banned ingredients?**
The simplest approach is to read the INCI list (the ingredients panel, usually in small print on the back). EU and UK law requires every cosmetic product to list ingredients in descending order of concentration. If you’re unsure about a specific ingredient, the European Commission’s CosIng database is free and searchable. Apps like Yuka and INCI Beauty also scan barcodes and flag ingredients of concern. From mid-2026, labelling rules will be stricter, making this easier than it has been.
