Peptides
Short chains of amino acids that signal the skin to behave a certain way — most often to build collagen. Evidence varies sharply by the specific peptide; "peptides" on a label is a category, not a guarantee, and the exact sequence and concentration decide whether they do anything.

Peptides by the numbers.
The DermFND database tracks 364 products formulated with peptides, most often in moisturizers (100 products) but also across serums and eye creams. Those products average a 73/100 formulation score — above the catalog norm — topping out with L'Oréal Paris Revitalift Derm Intensives 1.5% Pure Hyaluronic Acid Serum at 88/100.
87 formulas containing peptides clear our 80/100 standout threshold. Its most frequent formulation partners are Hyaluronic Acid (172 shared formulas) and Niacinamide (153 shared formulas). The median price of a peptides product here is $52.
