In Peckham, southeast London, the investigators purchased a tube of Fashion Fair Cream from two shops.
This product is unlicensed in the UK and contains Clobetasol Propionate, a prescription-only steroid used for the treatment of illnesses such as eczema or psoriasis.
Due to the risk of hazardous side-effects, its use should be controlled by a doctor, and it should not be sold over the counter to the general public.
