Topical retinoids are an important class of drugs for treating several dermatoses occurring more frequently in patients with pigmented skin, such as melasma, post-inflammatory hyperpigmentation, pseudofolliculits barbae and keloids. They also play a role in managing acne, psoriasis, photoaging, cutaneous T-cell lymphoma, Kaposi sarcoma and disorder of hyperkeratosis in this demographic as well. ⋯ There is little evidence to suggest that patients with darker skin are at increased risk of irritation. However, retinoid dermatitis can induce post-inflammatory hyperpigmentation and attempts should be made to reduce its occurrence by modifying treatment regimens in patients with pigmented skins.
