In order to achieve the best results for anti aging, be sure to implement a retinol into your daily regimen. A retinol is an advance skin care product that consists of antioxidants and soothing ingredients that reduce the signs of aging and helps blend in fine lines. This product will assist in achieving your maximum potential of a healthier youthful looking skin. We highly suggest using SkinMedica's Retinol Complex. Deciding which Retinol Complex to start with will depend on your skins familiarity with the product. If you are just beginning to use a retinol, then consider the 0.5 or the 0.25 Retinol Complex.
