What the science says
Peptides have some evidence of helping with signs of aging, and all three studies that tested them directly found they improved wrinkles, firmness, or skin texture 1. In comparisons, a peptide serum reduced crow's feet and forehead wrinkles more than retinol did, and peptides improved firmness more than a growth-factor serum, though wrinkle changes in that comparison were small 1. Reported side effects were stinging and itching, and one study reported none 1.
