What are the benefits of peptides?
According to board-certified dermatologist Dr. Jenna Queller, peptides are a key anti-aging ingredient because they are "proven to penetrate and stimulate collagen production."
Unlike topical collagen, for example, peptide skincare is "designed to reach deeper layers of the skin and signal collagen production."
Since peptides penetrate deep into the skin to boost collagen, consistent use can result in bouncier, firmer skin. Additionally, it'll help smooth fine lines and wrinkles, support skin elasticity, and tighten the appearance of pores.
