Copper Peptide / Tripeptide-1
A naturally occurring copper-binding tripeptide that declines with age. Stimulates collagen and elastin, promotes wound healing, exerts anti-inflammatory and antioxidant activity, and upregulates genes associated with skin regeneration. One of the most regenerative OTC ingredients available.
This concentration sits at or below the 1% line — that's expected and effective for this ingredient. Below the 1% line isn't automatically fairy-dusting; some ingredients genuinely work at low doses.
PM serum 0.05–1%. Avoid Vitamin C and strong acids which destabilise the copper ion. Allow 20 min after cleansing before applying.
