Other than sun avoidance, sunscreen application is the single most effective anti-aging preventative. Ultraviolet rays from the sun cause discoloration and wrinkling of the skin. Compare the skin on the face or chest with skin on unexposed areas of the body, like the breast or buttocks. Unexposed and exposed skin are the same age but unexposed skin always appears less wrinkled and more evenly pigmented, it has better tone and texture. Sunscreen prevents the skin discoloration and wrinkling and, as recent studies suggest, may even improve skin tone and texture.
Skincare moisturizers that claim to be "anti-aging" or "age defying" fill drugstore shelves. They often contain "marketing tool" ingredients that have never proven to rid of wrinkles or fine lines, certainly not at the concentrations used in the over-the counter (OTC) formulations. The fact remains, science has yet to find a single ingredient or product that can reverse or slow the aging process. In addition, by law, any skincare product sold in the United States that claims to actually change the skin is classified as a drug and must get FDA pre-market approval. It cannot be sold as an OTC cosmetic. (Cosmetic vs. Drug) Terms like "anti-aging" and "age defying" seen on skincare product labels are brilliant marketing phrases. The true benefit of including these terms on facial moisturizer labels, increased sales!
