UK Skin Lightening Cosmetic Rules

Under the GB Cosmetics Regulation, none of these three can be used to lighten skin. Hydroquinone is prohibited except in artificial nail systems, mercury and its compounds are prohibited, and corticosteroids (clobetasol, betamethasone) are prohibited as a class. OPSS has published about 100 notices since 2022 on skin lightening and steroid creams, almost all for hydroquinone, clobetasol propionate or mercury. The most recent was in July 2026.

Approach: I searched the GB-retained Cosmetics Regulation (Reg. 1223/2009 as amended by Schedule 34 to SI 2019/696, legislation.gov.uk), the Cosmetic Products Enforcement Regulations 2013 and the OPSS cosmetics product safety notices. The OPSS notices run from 2022 to July 2026.

1. Annex II and III status (GB)

Ingredient	Entry	What the GB text says
Hydroquinone (CAS 123-31-9)	Annex II ref 1339	Prohibited, "with the exception of entry 14 in Annex III" [1]
	Annex III ref 14	The only permitted use: artificial nail systems, max 0.02% after mixing, professional use only, with set warnings [2]. Mequinol has the same nail-only limit (ref 95) [3]
Mercury and its compounds	Annex II ref 221	Prohibited, "except those special cases included in Annex V" [4]
	Annex V refs 16, 17	The only exceptions: thiomersal and phenylmercuric salts as preservatives in eye products, max 0.007% Hg [5][6]. No skin cream exception.
Glucocorticoids (corticosteroids)	Annex II ref 300	Prohibited as a class [7]. Clobetasol has no entry of its own; OPSS treats clobetasol propionate as a glucocorticoid caught by this ban [8]
Tretinoin (retinoic acid and salts)	Annex II ref 375	Prohibited [9]

• Article 14 bars Annex II substances outright and allows Annex III substances only within their limits ^[10].
• Article 17 allows only small, unintended traces that are "technically unavoidable in good manufacturing practice" and still safe under Article 3 ^[11]. Deliberately added percentages of these substances are not covered.
• I found no Annex entry under the names arbutin or kojic acid in the GB text I searched.

2. What the OPSS notices show

All notices are listed in the panel document: 93 skin lightening or toning products and 7 creams that OPSS classed as "Steroid cream".

Most recent:

• Pr. Francoise Bedon Carotte Lightening Body Lotion (9 July 2026): acted on "according to the list of ingredients" alone (hydroquinone). The import was rejected at the border and destroyed ^[12].
• Faiza Beauty Cream (February 2026): 1.9% mercury, withdrawn from the market ^[13].
• Tibet Snow Cream (February 2026): "excess of mercury", withdrawn ^[14].
• Seven Nigerian lotions (December 2025): imports rejected at the border. Skin Nourish, for example, had 2.9% hydroquinone plus 0.007% clobetasol propionate ^[8].
• Goldie Advanced Beauty Cream (August 2025): 1.7% mercury and 0.15% clobetasol ^[15].

How OPSS acts:

• Nearly all are product safety reports rated "serious". Measures are border rejection, destruction, market withdrawal or removal of online marketplace listings (eBay).
• One notice is typed as a consumer recall: Golden Pearl Beauty Cream, 1.5% mercury, recalled from end users by Sash Cosmetics (October 2024) ^[16].
• A 2024 series covered Makari products sold via eBay and Amazon: clobetasol propionate at 19 to 472 mg/kg, or about 3% hydroquinone, all withdrawn (for example ^[17]).

Other substances in lightening products:

• Lilial in Glow & Lovely (March 2026) ^[18].
• MCI/MI in a leave-on product ^[19].

3. What an importer or retailer must check

If you import, you are the Responsible Person (Article 4(5)) unless you appoint a UK-established person by written mandate and they accept in writing. A distributor also becomes the Responsible Person if it sells the product under its own name or changes it ^[20]. Before placing the product on the market, the Responsible Person needs:

1. Formulation screen: no Annex II substances, Annex III used only within limits ^[10]. Given the alert pattern, analytical testing for hydroquinone, mercury and corticosteroids is the obvious control for supplier-sourced lightening creams.
2. Safety assessment: a safety report by a qualified assessor under Article 10 and Annex I ^[21].
3. Product Information File: in English, kept for 10 years after the last batch, at the address notified ^[22].
4. Notification: submitted to the Secretary of State before placing on the market ^[23].
5. Labelling: Responsible Person's name and address, country of origin for imports, batch number, INCI list and Annex warnings ^[24].
6. Claims: must meet the Regulation 655/2013 criteria ^[25].
7. Corrective action and reporting: if the product is non-compliant, correct, withdraw or recall it; if it is a health risk, tell the authorities immediately ^[26].

Retailers and distributors (Article 6):

• Before selling, check that the Responsible Person's name and address, the batch number and the ingredient list are on the pack, that the language rules are met, and that the durability date has not passed.
• Do not sell a product you have reason to believe is non-compliant. If you have already sold a risky product, inform the Responsible Person and the authorities ^[27].
• An ingredient list showing hydroquinone or a steroid is, by itself, reason to refuse the stock: OPSS acted on the ingredient list in the Bedon case.

Enforcement exposure:

• Breaking Articles 3, 5, 6, 14, 19 or 20 is an offence. The maximum on indictment is a £20,000 fine and/or 12 months' imprisonment ^[28][29].
• Products can be forfeited and destroyed ^[30].
• The due diligence defence requires "all reasonable steps". Relying on a supplier's information counts only if that reliance was reasonable, considering what you did to verify it ^[31]. So documented supplier checks and test certificates matter.
