Retinoids are used to treat acne, psoriasis, and signs of aging like wrinkles. They also have other uses. Retinoids work by speeding up cell turnover, which helps to clear up skin and reduce inflammation. These medications come in different forms, including topical creams and oral capsules. Examples include tretinoin (Retin-A, Atralin, Avita), isotretinoin (Accutane, Absorica, Claravis), tazarotene (Tazorac, Avage), and adapalene (Differin, Differin OTC).
