Isotretinoin cream (topical isotretinoin) is a vitamin A derivative used to treat acne by reducing oil (sebum) production, inflammation, and bacteria, offering a localized treatment with fewer systemic side effects than oral versions, making it suitable for mild to moderate acne or patients who can't tolerate oral isotretinoin, though its availability varies by region (like being discontinued in the UK). It works best over weeks to months, requires sun protection, and, like oral isotretinoin, carries risks, particularly severe birth defects, necessitating strict pregnancy prevention for childbearing potential
