Retinol, a Vitamin A derived wrinkle cream, is an important component of your skin care routine. Retinol is a type of retinoid, which has a small enough molecular size to penetrate into the deeper layer of the epidermis to help repair the dermis. This helps promote collagen and elastin production.
Retinol needs to be converted into retinoic acid to yield beneficial results on your skin. The difference is that retinoic acid is stronger and only available with a doctor’s prescription. Retinol can be purchased over the counter.
Although pure retinoic acid offers very good anti wrinkle results, it can irritate skin and cause other problems.
A large number of retinol skin cream products don’t use a sufficiently high concentration to do much good. You want preparations that contain 1,000,000 International Units per ounce (equivalent to about 1.0% retinol).
