All about tretinoin: the facts your skin wants you to know
Tretinoin may not be all that easy to pronounce, but its users find it very easy to love. Also known as all-trans retinoic acid, tretinoin is part of the retinoid family—a class of synthetic and naturally occurring Vitamin A compounds and derivatives. Compared to its cosmetic relatives such as retinol, retinaldehyde and retinyl esters, tretinoin is the most potent. For Important Safety Information about tretinoin, please see below.
Tretinoin was originally developed as an acne treatment in the 1960s. But while researchers were studying its powers to resolve breakouts, they noticed that patients who used it were getting an unexpected bonus: an improvement in the appearance of photoaged skin.
This prompted scientists to set up new, well-controlled clinical trials. Users in these trials experienced improvements in wrinkling, pigmentation and roughness—as well as in the overall severity of photoaging.
How does Tretinoin work?
The exact mechanism of action of tretinoin is not known, however researchers believe tretinoin encourages rapid epidermal turnover—so skin releases dead cells faster than it otherwise would, and reveals a fresh, glowing complexion. At the same time, it boosts production of skin’s vital collagen and remodels elastin, which break down with natural aging and photoaging.
Under the microscope, researchers have seen tretinoin produce significant changes in epidermal and dermal skin cells and tissues. Out in the real world, users see an improvement in their acne, and with the tretinoins approved for the treatment of fine lines and wrinkles, pigmentation and roughness, users see an improvement in these signs of photaging.
Tretinoin takes skin care to a new level
Available by prescription only, tretinoin can have significant results when used on its own, and it can add a boost to any skin care routine. Ask your skin care professional about the potential advantages of tretinoin for you as an addition to your skin care regimen.
