HOW DO RETINOIDS WORK?
Recent studies show the Retin-A erasing wrinkles was stimulated by observations made in adult-women with persistent acne. After Retin-A treatment, they often described smoother, and less wrinkled skin.
Retin-A, the acid relative of vitamin A, has been available since 1971. It has been an important treatment for acne pimples and blackheads, since its major action is to dissolve the glue holding the very top of the skin (known as Epidermis) to undersurface. By this lifting or peeling off the top layer of the skin, it is able to lift off the unglue blackheads and other skin blemishes over several weeks time. .
To understand how retinoids work, we need to first know a little about collagen. Collagen is a protein that provides structure to the body, as well as sustaining firmness and elasticity. Any decrease in collagen causes our skin to become thinner. Aging of the skin is due to two factors: intrinsic (which includes our genetics, as well as the natural act of aging) and extrinsic (which includes damage from the sun’s UV rays, smoking, and pollution).
Our cells are always going through a constant regeneration process, but it begins to slow down with age, and collagen manufacturing also gets reduced. This is where retinol creams come in.
