The star ingredient in the The Ordinary Buffet Signs of Ageing Serum ($17) is its peptide complexes combined with a "probiotic complex in a base of hyaluronic acid and amino acids," Dr. King says. "This serum also contains glycerin, allantoin, urea, and castor oil. Urea and glycerin are great humectants to hydrate the skin, while allantoin heals, soothes, and protects, as well as stimulates the growth of healthy skin tissue. Castor oil which is rich in fatty acids, is anti-inflammatory, antimicrobial, hydrating and moisturising."
