Get the appWhat it does
Peptides are broken-down proteins composed of 2–50+ amino acids linked together. They penetrate the skin barrier more easily than full proteins and signal fibroblasts to increase collagen and elastin synthesis, improving skin structure and firmness. Different peptide sequences target specific skin concerns—some mimic neurotransmitters to relax expression lines, others boost hydration or barrier repair.
