@hnrlabs: Your body makes a copper-based molecule that drops as you age — and it's part of why older skin repairs itself more slowly. It's called GHK-Cu 🧬 GHK-Cu (copper tripeptide-1) is a tiny peptide bound to a copper ion, found naturally in your body. The striking part: levels are high when you're young and fall a lot with age — by your 60s they can be under half of your 20s levels. That drop tracks with skin's slowing ability to repair. It works like a repair signal — studied to attract repair cells to damage, remodel the skin's structure, and prompt collagen and elastin (the proteins that keep skin firm and springy). It signals the skin to rebuild from within. Of the peptides used topically in skincare, it's one of the better-studied — research supports improvements in firmness, elasticity and fine lines. Honest bit: genuinely one of the more evidence-backed cosmetic peptides, but the effects are gradual, not overnight, and depend on a well-formulated product (copper peptides are tricky to formulate). Real ingredient, patient expectations. ⚠️ Not medical advice — for educational purposes only. Is this one in your routine? 👇 #ghk #copper #skincare #collagen #skintok
