The best anti-aging moisturizers work through the way their ingredients interact with the skin. Ingredients such as retinol, which is a form of vitamin A, speed up the growth of skin cells, while hydroxy acids exfoliate the dead skin and help promote the skin rejuvenation process.
Anti-aging moisturizers also contain copper peptides, which help smooth the skin and improve its ability to stretch. Additionally, they enhance the healing factor of the skin by increasing the production of collagen. The main function of anti-aging moisturizers is to reduce lines and wrinkles by hydrating the skin cells. However, anti-aging moisturizers do not rejuvenate fat cells.
