Skin lightening cream UK law on hydroquinone, mercury, steroids

Skin lightening cream UK rules for importers and sellers

A skin lightening cream sold in the UK must meet the cosmetics rules on safety, labelling and restricted ingredients. Hydroquinone, mercury and its compounds, and corticosteroids such as clobetasol are banned in a skin whitening cream sold as a cosmetic (GOV.UK guidance, Annex II). Products containing them have been rejected at the border, seized, withdrawn or recalled (GOV.UK product safety alerts). Selling a product that breaches those bans is a criminal offence.

Importers, Responsible Persons and sellers of skin lightener or "even tone" products need to check more than the label. The Pretty White! alert found hydroquinone that the ingredients list did not declare.

The law that applies

In Great Britain (England, Wales and Scotland), cosmetics fall under Regulation (EC) No 1223/2009 as amended for GB by the Product Safety and Metrology etc. (Amendment etc.) (EU Exit) Regulations 2019 (GOV.UK). Annex II lists prohibited substances. Annex III lists restricted ones with limits and conditions.

GOV.UK names skin-whiteners as a cosmetic product type and gives a direct warning: "Be particularly cautious if buying skin-whiteners or black spot treatments. These regularly appear in the UK list of product safety reports, recalls and alerts as they have been found to include banned substances" (GOV.UK).

Hydroquinone cream and banned skin bleaching ingredients

So a hydroquinone cream for the skin can't be a legal cosmetic in the UK. The single exception is professional artificial nail systems, and the label must say "For professional use only", "Avoid skin contact" and "Read directions for use carefully". Mequinol (hydroquinone methylether) has the same nail-only limit at Annex III entry 95.

Clobetasol has no Annex entry of its own. The class entry for glucocorticoids catches it, and OPSS alerts say so in plain words: "Clobetasol propionate is a Glucocorticoid (Corticosteroid) which is prohibited in cosmetic products" (OPSS alert). In the UK, clobetasol is a prescription-only steroid medicine, sold under brands such as Dermovate (NHS). A skin lightening cream that contains mercury is also a mercury-added product under the Minamata controls (GOV.UK).

Don't count on the trace rule. Article 17 allows only "non-intended presence of a small quantity of a prohibited substance" that is "technically unavoidable in good manufacturing practice", and only if the product is still safe. A deliberately added active is outside it.

What OPSS and Trading Standards alerts show

The Office for Product Safety and Standards (OPSS) publishes a steady stream of product safety notices on skin lightening and steroid creams. Nearly all are product safety reports rated "serious", notified by local authority Trading Standards. Some recent ones:

The Bedon lotion came from France, and that alert based the "serious chemical risk" on hydroquinone in the ingredients list. A named banned ingredient is enough to refuse the stock. A clean ingredients list is not enough.

Other banned ingredients show up too. A Glow & Lovely serum in cream (4 Mar 2026) was withdrawn for butylphenyl methylpropional (lilial), which is "not permitted in cosmetic products". Golden Pearl Beauty Cream, with 1.5% mercury, was "recalled from end users by Sash Cosmetics" on 4 October 2024. End-user recalls are rare in these notices.

The alerts link hydroquinone to allergic contact dermatitis, mercury to damage to internal organs and the nervous system, and clobetasol to possible endocrine damage.

How to tell a legal product from an unsafe one

If you import, you are probably the Responsible Person

A cosmetic can't be placed on the GB market without a Responsible Person established in the UK (Article 4). An importer is the Responsible Person unless it appoints a UK-established person by written mandate and that person accepts in writing. A mail forwarding or PO box address doesn't count as UK established, and a distributor becomes the Responsible Person if it labels the product as its own (GOV.UK).

GOV.UK lists the Responsible Person's duties. Before the product goes on sale, it must:

• know the ingredients and the restrictions that apply to them
• hold a Product Information File in English, kept for 10 years after the last batch
• have a Cosmetic Product Safety Report signed by a qualified safety assessor
• notify OPSS through the Submit cosmetic product notifications (SCPN) service
• report serious undesirable effects, and be able to prove marketing claims

The label needs the Responsible Person's name and address, the country of origin if imported, a batch number, the ingredients list and any precautions, in English (GOV.UK). If the Responsible Person has reason to believe a product is non-compliant, it must bring it back into compliance, withdraw it or recall it (GOV.UK GB guidance).

For imported whitening creams, a supplier's ingredients list is weak evidence. Pretty White! and the Southwark serum both contained hydroquinone that the list did not name. A label check cannot rule out undeclared hydroquinone, mercury or corticosteroids, so ask for analytical test results for these substances.

If you sell, check before you list

Retailers and online sellers are distributors under Article 6. They must act "with due care". Before selling, they must check that the Responsible Person's name and address, the batch number and the ingredients list are on the label, the language rules are met and the date of minimum durability hasn't passed. If they have reason to believe a product doesn't conform, they can't sell it until it does. If a product already sold presents a risk to health, they must "immediately inform the responsible person and the competent authorities".

GOV.UK's buyer warning signs work as a stock screen too: purpose not clear, product information missing or not in English, no named Responsible Person, a PO box or mail forwarding address, or a "professional use only" marking (GOV.UK). SCPN notifications aren't public, so a seller can't look one up. Ask the Responsible Person for evidence of notification.

Penalties and the due diligence defence

Breaching Articles 3 (safety), 5 (responsible persons), 6 (distributors), 14 (annex restrictions) or 19 (labelling) is an offence under the Cosmetic Products Enforcement Regulations 2013. On summary conviction, regulation 13 sets a fine up to the statutory maximum, or up to three months' imprisonment, or both. On indictment, it sets a fine up to £20,000, or up to twelve months' imprisonment, or both. In England, Wales and Northern Ireland, an enforcement authority may apply to a magistrates' court for forfeiture where Article 3 has been breached (regulation 20).

Regulation 23 gives a defence if you took "all reasonable steps and exercised all due diligence". Relying on a supplier's information only works if it was reasonable, given the checks you made and whether you had reason to doubt it. If that defence blames another person's act or information, serve notice at least seven clear days before the hearing.

Southwark Council prosecuted an eBay seller who imported mostly from Ghana, Nigeria and Thailand. He sold over 20,000 cosmetic products, worth about £340,000, between March 2020 and January 2023. Test purchases found hydroquinone or corticosteroids, and one serum held 10% hydroquinone with neither substance on its ingredients list. Officers seized 1,700 products. He admitted doing none of the required checks and received a six-week prison sentence suspended for 15 months, plus £4,750 in fines and costs, at Inner London Crown Court.

Northern Ireland

Under the Windsor Framework, Northern Ireland follows the EU cosmetics regulation. The Responsible Person must be in Northern Ireland or the EEA, not GB, and notifies through the EU CPNP, with district councils enforcing (GOV.UK NI guidance). A product sold in both markets needs a UK-established Responsible Person and an SCPN notification for GB as well.
