Q.I am just 24 years old but I want to start preventing wrinkles and future signs of aging. Other than daily sunblock, what else do you recommend as a must in my skin regimen?

A.Your New Year's resolution should be daily skin care. The literature is overwhelming supporting antioxidants, retinoids and exfoliating agents. Use of these products on a daily basis will help reverse some of the deleterious effects of photoaging. Sunscreen/block (SPF 15 or above) twice daily is essential.
