Tretinoin 0.1% Cream 45gm

Tretinoin is a metabolite of Vitamin A that binds to specific retinoic acid receptors (RARs) in the nucleus, which then bind to DNA and modulate gene expression. This leads to altered cellular differentiation, proliferation, and inflammation. In acne, it promotes follicular epithelial cell turnover, reduces cohesion of follicular epithelial cells, and facilitates extrusion of comedones, thereby reducing microcomedone formation. For photoaging, it increases collagen synthesis, reduces epidermal melanin, and promotes angiogenesis.
