Elizabeth ArdenAsk a Derm: Do peptides actually do anything for your skin? The short answer? They do. Dr. Mary of our Derm Collective breaks down why peptides are one of the most talked-about skincare ingredients: they help signal skin to support collagen and elastin production, two essential components of firmer-looking skin. That's why our Hyaluronic Acid + Peptide Ceramide Water Cream is formulated with 16,000 signaling peptides to help visibly enhance firmness.
