Is Hydroquinone Prescription-Only in the UK?

In short: yes. Hydroquinone is prohibited in cosmetic products under UK cosmetics regulations (Annex II, retained from EU Regulation 1223/2009), so it can't legally be sold over the counter as a skin-lightening cream. It can be prescribed and supplied as a prescription medicine, usually at 2–4%, for limited courses after a medical assessment.

Why can't you buy hydroquinone over the counter?

Unsupervised, long-term or high-strength use can cause irritation and, rarely, ochronosis (a blue-grey darkening). Creams sold illegally may contain undeclared or excessive amounts, and sometimes mercury or strong steroids. A prescription means the right strength, course length and aftercare.

What does 4% hydroquinone mean?

It is the concentration of the active ingredient. 4% is commonly prescribed for melasma, sun spots and post-inflammatory hyperpigmentation.

How is it used?

Typically once or twice daily on affected areas for a course of around 3–6 months, often with breaks and with strict daily SPF. It is sometimes prescribed alongside tretinoin; see our tretinoin guide.

Non-prescription alternatives

Azelaic acid, vitamin C, tranexamic acid, niacinamide and retinoids can all help pigmentation, more gradually. Sun protection underpins every option.
