If you looking for a product that will treat the damage done to your skin through years of sun exposure try creams and lotions (creams are usually thicker than lotions) containing lactic acid. Regular use of AHA topical creams or lotions is known to reduce the appearance of fine lines and wrinkles because it stimulates collagen production in your skin.
They're also known to improve hyperpigmentation, dark patches or spots that develop on the skin. When you use products that contain concentrations of more than 5 percent lactic acid in their ingredient list, you may find it lightens your skin, which is exactly what you want if you have age spots or other discoloration.
Applying AHAs in cream or lotion form is also helpful in treating dry skin. A cream that contains, for instance, lactic acid and an emollient or humectant is a two-step knockout: the lactic acid first thoroughly exfoliates the skin, allowing more moisture through to the new skin below.
