peptide
Peptides are short chains of amino acids that can signal skin cells to produce more collagen and elastin. The category is broad and evidence quality varies dramatically — some peptides (like Matrixyl) have decent clinical data, while many others are supported by little more than in vitro studies and marketing enthusiasm.
hydrator
The structural supporting molecules in the dermis — increasingly added to anti-aging formulas as an HA complement.
