What can i reasonably expect to obtain from using retina-a cream as a facial enhancement?

Takes time.: Retinoids like Retin-A cosmetically enhance by stimulating skin turnover and promoting new collagen to form/build. However, it takes several months to see the results of the collagen stimulation as the incubation for collagen is approximately 4 months. In the interim, make sure you moisturizing well to avoid the possible irritating side effects of a retinoid.
