This study aims to identify the corticosteroids in whitening cosmetic preparations circulating in Gorontalo City. The method used in this study was thin layer chromatography (TLC), with a qualitative approach and a descriptive (observational) type of research. The results showed that identification in the UV laboratory at a wavelength of 254 nm showed that from the 5 cream samples and 5 lotion samples for whitening cosmetic preparations tested, four of them were positive for the strong drug class of corticosteroid betamethasone valerate, namely with an Rf value on (cream sample E 0, 91), (lotion sample A 0, 91), (lotion sample B 1.0), and (lotion sample C 1.0) and have Rf values identical or similar to standard Rf values under the same chromatographic conditions.
