What is Isotretinoin and How Does It Work for Acne? Isotretinoin is a powerful oral medication primarily used to treat severe acne that hasn’t responded to other treatments. It belongs to a class of drugs known as retinoids, which are related to vitamin A. Isotretinoin works by reducing the size and activity of the oil (sebaceous) glands in the skin. This leads to less oil production, which helps prevent clogged pores—a major cause of acne. Additionally, isotretinoin has anti-inflammatory properties and reduces the growth of acne-causing bacteria. Over time, this results in a significant reduction in acne lesions, including deep cysts and nodules. It is often prescribed for people with severe nodulocystic acne or persistent breakouts that cause scarring. While highly effective, isotretinoin can have serious side effects and requires close monitoring by a healthcare provider, including regular blood tests and pregnancy prevention measures for women of childbearing age.
