Peptides are an important part of restoring your skin so it looks and feels healthy. Most notably for skin, peptides tell your cells to produce more collagen. Collagen is an important structural protein that keeps skin firm and plump. For you, that means peptides can offer a more youthful complexion with fewer fine lines and a better glow.
Peptides are naturally-occurring short strings of amino acids in your body, which are the building blocks of protein. They're able to communicate with surrounding cells and activate certain restorative processes. Peptides are often added to serums, moisturizers, and masks.
Peptides are best for those concerned with fine lines, wrinkles, or sagging skin. When planning your routine, bear in mind that AHAs will make peptides less effective.
