When seeking a topical cream to help repair sun damage, it's important to see if a product incorporates “DNA repair ingredients,” which specifically stimulate collagen production in the skin. DNA-repairing ingredients can help undo damage to the cells and prevent cell death from exposure to ultraviolet rays.
Hyaluronic acid is another ingredient found in effective skin treatment products. It can help absorb moisture and fill in wrinkles to smooth the skin for short periods of time. Furthermore, glycolic acid works to exfoliate dead skin cells and smooth the skin as well as stimulate collagen production. Finally, vitamin C can help protect the skin from free radicals, which are found in the environment and caused by UV exposure. The vitamin can be absorbed through the skin and helps to promote cell growth and collagen production.
