When collagen is depleted by age and environmental factors, including sunlight, it is not fully replaced. As a result, smooth, young skin slowly becomes thinner and wrinkled over time. As collagen deteriorates, it produces certain peptides. When skin care peptides are applied topically, your skin “thinks” that it’s a collagen break down product and that your body needs to manufacture new collagen. So you can successfully minimize wrinkles and give your skin a more youthful appearance with the application of skin care peptides that trigger the production of collagen.
