In contrast, many peptides—which are chains of amino acids—operate at a more neutral pH.
When people ask, "Why can't you use vitamin C and peptides together?" they are often referring to the potential for the low pH of L-ascorbic acid to potentially destabilize certain peptide structures. However, Vitamin C and peptides are widely used in Feb 3, 2026 — Yes, you absolutely can use vitamin C and peptide serums together!
