Clinical Pharmacology

Although the exact mode of action of tretinoin is unknown, current evidence suggests that topical tretinoin decreases cohesiveness of follicular epithelial cells with decreased microcomedo formation. Additionally, tretinoin stimulates mitotic activity and increased turnover of follicular epithelial cells causing extrusion of the comedones.


Side effects and sunscreen use

When used, dryness of the affected skin may occur. Application of sunscreen while using tretinoin is strongly recommended.
