Retin-A started out as a cream prescribed for acne, yet it also had another interesting side-effect... it reduced fine lines and wrinkles also with regular use.
It is a derivative of vitamin A. It works by increasing blood flow and stimulating skin cells called fibroblasts to produce new collagen, (the protein in skin cells that keep skin smooth). This can help to eliminate tiny wrinkles and make deep wrinkles less noticeable. The top layer of skin also thickens and produces a more youthful appearance.
