Most people hear “copper peptide” and think “trend”. But GHK-Cu isn’t new, it’s a naturally occurring bioregulator your body already uses to repair, rebuild, and rejuvenate skin.

In this episode of Biohacking Beauty, we break down why GHK-Cu deserves its cult status in longevity skincare. We also unpack how this tripeptide binds copper to signal fibroblasts, activate collagen and elastin genes, and restore damaged tissue at the cellular level. You’ll learn why 3% is the sweet spot for results without irritation, how GHK-Cu works synergistically with retinol, vitamin C, methylene blue, and NAD+, and what makes pharmaceutical-grade sourcing critical for performance.

If you’ve ever wondered whether GHK-Cu can truly “reset” aging cells or how it compares to retinol, this episode connects the dots between biochemistry and visible results, showing how small, precise molecules can drive profound, measurable change in your skin’s longevity.
