Topical androgen-receptor blocker, approved as an acne cream

Clascoterone, sold under the brand name Winlevi, is an antiandrogen medication which is used topically in the treatment of acne. The medication is used as a cream by application to the skin, for instance the face and scalp. Clascoterone is an antiandrogen, or antagonist of the androgen receptor (AR), the biological target of androgens such as testosterone and dihydrotestosterone. It shows minimal systemic absorption when applied to skin.
