You can help to prevent age spots by regularly using sunscreens before the age of 40, avoiding prolonged sun exposure and wearing protective clothing. Putting these recommendations into practice will also help to reduce your chances of developing skin cancer, wrinkles and other sun-related skin changes. The routine use of cosmetic products containing an exfoliating ingredient can serve to lighten freckles and age spots by removing the superficial layer of dead skin cells to reveal fresher-looking skin. A convenient way to incorporate an exfoliant into your daily skin care routine is to find one that’s included in a moisturizer. You may also want to look for a formulation with niacinamide as an active ingredient. Niacinamide is a B-complex vitamin that plays an important role in maintaining healthy skin by improving its barrier function and helping to lighten areas of the skin with darker pigmentation.
