THE BENEFITS STILL PREVAIL RP, along with its fellow vitamin A deriv- atives, has been proven to increase collagen content and skin thickness, both classic fea- tures of healthy skin. In addition, it helps to regulate immune function in the skin, adding another level of defense against skin cancer. In cosmetic formulations, including sunscreens, this molecule is added in trace amounts as a stabilizer, protecting the product from light-induced breakdown. Dermatologists for decades have prescribed retinoids includ- ing RP for the treatment and prevention of numerous skin conditions, including precancerous skin lesions and skin cancers. Regular use of a topical retinoid ultimately improves the skin's ability to defend itself from the harmful rays of the sun. It is only during the initial weeks of starting a retinoid product that the skin becomes sun-sensitive, but once it is acclimated, the rejuvenated, more resilient epidermis, with potential precancers cleared away, will actually perform better under stress- ful environmental conditions including UV ra- diation. 1-4, 9 In other words, the many PROVEN benefits of retinoid use vastly outweigh the unproven risks suggested by an unpublished rodent study.
