Lustre provides nutritional support for healthy-looking hair, skin, and nails. It contains nutrients to support skin repair and growth, such as vitamin A, folic acid and zinc. It also supplies proline, vitamin C and silica, all of which help form hydroxyproline. Hydroxyproline is the key constituent of collagen, a form of connective tissue that provides underlying firmness, tautness and elasticity to skin. In addition, this comprehensive formula contains potent antioxidants to protect against free radicals, including vitamin E, selenium and beta carotene. And Lustre provides nutrients to support healthy hair and nails, such as the sulfur-containing amino acid cysteine. Cysteine is a building block for alpha-keratin, the primary protein found in hair and nails.
