Tolerability of tretinoin lotion 0.05% for moderate to severe acne vulgaris: A post hoc analysis in a black population

Abstract

Acne vulgaris (acne) is the most common dermatologic disorder seen in black patients. However, data are lacking on the effects of treatments, such as topical retinoids. Acne in black patients is frequently associated with postinflammatory hyperpigmentation (PIH), which can be of greater concern than the patient’s acne and often is the main reason these patients seek a dermatologist consultation. Retinoids can treat both acne and PIH. However, the potential for retinoids to induce an irritant contact dermatitis, which could lead to PIH, is a concern. A lotion formulation of tretinoin was developed to provide an important alternative option to treat acne in black patients who may be sensitive to the irritant effects of other tretinoin formulations or where PIH is a concern.
