Why is it so important to use a sunscreen when using products that contain AHAs?
Since sun damage is a major factor in the premature aging of skin, you need to wear a sunscreen whether or not you use AHAs. However, use of a sunscreen with SPF 15 or higher during sun exposure is a must when using alpha hydroxy acids and for a week after you discontinue use of products containing them. Remember, AHAs reveal younger, fresher skin cells and they are more vulnerable than the old dead skin cells that were glued to the top of the skin before you started using AHAs.
