Cellular renewal, scientifically substantiated.
GHK-Cu complex for skin renewal and collagen synthesis. The gold standard of peptide skincare.
Free shipping on orders over $80 · Formulated in small batches
Our Copper Peptide Serum delivers GHK-Cu (copper tripeptide-1) at a clinically relevant concentration — the same compound studied for decades for its role in skin regeneration. GHK-Cu supports collagen and elastin production, promotes cellular turnover, and helps neutralize free radicals. The result is visibly firmer, smoother skin over weeks of consistent use.
Every peptide listed. Every concentration disclosed. No proprietary blends hiding ineffective doses.
INCI-style full disclosure. No hidden ingredients, no "fragrance" catch-all.
GHK-Cu is one of the most studied peptides in cosmetic science. Discovered in human plasma in 1973, it was identified as a potent signal molecule that tells aging skin to behave like younger skin. It activates genes involved in collagen production and downregulates genes linked to inflammation. Unlike retinol, it achieves renewal without irritation — making it suitable for sensitive skin types and those who cannot tolerate vitamin A derivatives.
Each formula targets a distinct biological pathway. They're designed to complement one another.
