One characteristic that gives youthful skin its natural glow is rapid cell turnover. Aging women and men can get the same effect by applying Retin A. Used by dermatologists as an acne treatment for decades, Retin A comes in cream form for fighting wrinkles. A dermatologist can prescribe the prescription strength, or you can purchase wrinkle cream with lower-strength retinols in the cosmetic department. Always follow Retin-A treatment with a moisturizer as the increased cell turnover can be drying to the skin. Since skin on the neck is much thinner than that of the face, avoid using full-strength Retin A on this area.
