Proline is an essential amino acid and one of the most important building blocks of collagen. It is a particularly good humectant moisturizing ingredient, able to retain more water than any other amino acid. It also has antioxidant activity and is able to decrease UV-induced oxidation of skin lipids.
Adding proline to a skincare formula may help to improve the healing of damaged skin and small cuts and wounds, simply because it can travel through the damaged skin and take part in the synthesis of the new collagen. The same study showed, however, that the oral intake of proline is even more effective than the topical application.
