Retinoids : I recommend the use of a retinoid to help even skin tone, repair minor sun damage, and rebuild collagen. While there are many products touted as “wrinkle reducers”, retinoids have been rigorous studied through research and have a proven track record of safety and effectiveness. Prescription products (retin-a, renova, (tretinoin) tazorac) are usually more effective than over-the-counter products.
