What is this medication?

Tretinoin (Topical), Retin-A/Stieva-A/Altreno/Atralin/Avita/Refissa/Renova
Acne Product; Retinoic Acid Derivative; Topical Skin Product

Officially indicated for acne vulgaris, palliation of fine wrinkles, mottled hyperpigmentation and tactile roughness of facial skin depending on which formulation is used.

How does this medication work? 

Tretinoin is a derivative of vitamin A and when applied topically to the skin is modified the epithelial growth and differentiation. In patients with acne, it decreases the cohesiveness of follicular epithelial cells and decreases microcomedone formation. Additionally, tretinoin stimulates mitotic activity and increased turnover of follicular epithelial cells causing extrusion of the comedones.
