الببتيدات

Peptides are short chains of amino acids — the building blocks of proteins like collagen — used in skincare to support the appearance of firm, smooth, resilient skin. They're among the most versatile and well-tolerated anti-aging ingredients, suitable for nearly every skin type and easy to layer. Different peptides do different things: signal peptides target the look of firmness, copper peptides support overall skin quality. Use a peptide serum consistently, morning or night, before your moisturizer. They pair well with almost everything, though strong direct acids in the same routine can reduce their effectiveness — separate them by time of day. HydroPeptide built its reputation here.
