Tretinoin use treats fine lines and wrinkles, brightens the complexion, and fades dark spots left by acne or sun damage. Because tretinoin is already a retinoic acid, it directly affects the skin. This allows you to potentially see improvement of the skin in six to eight weeks time.
Tretinoin is widely studied and has been proved to be a very effective anti-aging treatment that reverses wrinkles and sun damage. In one study,
participants were divided into two groups, one of which received non-prescription skincare products, and the other a 0.02% tretinoin cream in addition to moisturizing sunscreen. Over the course of eight weeks, participants in the tretinoin group saw a significant reduction in facial skin aging, with lower eye area wrinkle fraction, and an improvement in overall skin appearance after the treatment.
Another huge bonus of using tretinoin is that it reduces the risk of skin cancer. Tretinoin does reduce some signs of skin aging associated with chronic sun exposure. Used with topical DNA repair enzymes, it may help treat actinic keratoses and prevent basalcell and squamous cell carcinomas.
