GHK-Cu — aka copper peptides — has been crowned the "beauty peptide," but the real story is way bigger than anti-aging marketing. In this episode, we go deep on why this molecule (one your body already makes and relies on for repair) might be one of the most important things you can add to both your skincare routine and your supplement stack.

In this episode:

• What GHK-Cu actually is and why it's different from signal peptides
• How your natural GHK-Cu levels drop by more than half between ages 20–60 — and why that matters
• The four main jobs copper peptides do in the skin (and why "collagen stimulation" is just the beginning)
• The basal cell layer, P63 expression, and what it means when your skin cells stop acting like stem cells
• Why chronically inflamed skin (hi, acne-prone skin) needs copper peptides more than almost anyone
• How GHK-Cu supports post-procedure recovery and why it's one of the best things to microneedle with
• The vitamin C + retinoid compatibility conversation — what actually matters and what you can stop worrying about
• How to work copper peptides into your routine and what to look for on the ingredient list (hint: copper tripeptide-1)
