Isotretinoin
Isotretinoin is an active pharmaceutical ingredient primarily used in the treatment of severe acne. It is a retinoid derivative that works by reducing the production of sebum, a type of oil produced by the skin. Isotretinoin helps to unclog pores, prevent the formation of new acne lesions, and promote skin healing. Due to its potent effects, it is typically prescribed when other acne treatments have been ineffective. Isotretinoin requires careful medical supervision due to potential side effects and must not be used during pregnancy due to the risk of severe birth defects.
