Hair, skin and nails are comprised predominantly of keratin, a protein that helps create an strong, protective barrier. It is damage to the top layer of keratin that causes skin, hair, and nails to look unhealthy or dull. Beneath the outer keratin layer of skin is collagen, another protein that acts as a structural, connective framework, preventing sagging and wrinkles and signs of aging. While nothing can surpass the beauty benefits of a balanced diet and healthy lifestyle, the regular intake of some key nutrients for healthy connective tissue and protein formation, along with a good quality broad-spectrum antioxidant, can have you looking your best and feeling even better!
