Young skin looks smooth and wrinkle-free because of a surplus of collagen, which is the naturally occurring protein in our bodies that keeps us looking youthful. As we age and our skin does, too, we start to lose collagen and wrinkles appear. As the long strands of amino acids that appear in collagen start to break down, they create smaller chains called peptides, which signal to our bodies that more collagen needs to be made. Peptides in anti-wrinkle serums attempt to mimic this natural function to trick our face into creating more collagen.
There are particular peptides that are praised in skincare that specifically target different areas. Matrixyl is considered one of the most effective because it reaches lower levels of skin and not only encourages them to make more collagen, but also helps increase elastin, which improves your skin's elasticity, as well as hyaluronic acid, which plumps skin and helps reduce the appearance of wrinkles. Argireline is another peptide that helps relax tension in the face and therefore minimizes wrinkles. It's frequently compared to Botox, only it doesn't require injections. Eyeliss and Regu-Age are peptides that target the eye area by promoting lymphatic drainage that helps minimize puffiness and bags.
