Summary

This study tests a prescription cream (clascoterone) to treat acne caused by testosterone therapy in transgender men. About 18 participants will use the cream daily for 3 months to see if it reduces pimples without affecting their hormone levels. The goal is to provide a safe acne treatment that doesn't interfere with masculinizing hormone therapy.
