Tretinoin was the first, and still is the only topical treatment shown to improve the appearance of photoaged human skin through hundreds of robust clinical trials. It’s the real deal.

But don’t get actual retinoic acid (tretinoin) confused with over-the-counter, cosmetic vitamin A derivatives, which are not classified as medicines, and are not the same thing. These types of derivatives are found in many skincare products with the following names: retinol, retinaldehyde, retinal, retinyl esters, retinyl palmitate, retinyl propionate, retinyl retinoate and retinyl N-formyl aspartamate.
These ‘over the counter’ vitamin A derivative products are a total waste of time and
money. Don’t be scammed by Big Skincare.
