We can do without bloated tummies, but our skin can never be too plump. The key: hyaluronic acid. While this protein naturally occurs in skin, dry types should consider boosting stores with a moisturising serum or cream rich in the stuff, because hyaluronic acid has a fabulous ability to bind water in the dermis. The result: supple skin that looks less lined. Try the Advanced Cellular Renewal Serum, by Nude at Mecca Cosmetica.
