About

Flugestone is a cosmetic ingredient. Exercise caution due to limited available safety data.

Like other corticosteroids, it is prohibited in cosmetic formulations under EU Regulation 1223/2009 Annex II due to risks of dermal atrophy, systemic hormonal effects, and adrenal suppression associated with topical corticosteroid use.
