Our Copper Peptides Firming Serum pairs GHK-Cu (Copper Tripeptide-1, 0.10%) with Hyaluronic Acid (1.5%) in a minimalist 6-ingredient formula — no fillers, fragrances or unnecessary additives. Copper Tripeptide-1 is a reparative peptide that helps protect skin from damage, encourages collagen production and draws moisture back to the skin, for a firmer, more hydrated complexion with visibly fewer fine lines.

Use it day or night. Apply a small amount to clean, dry skin, gently massage in, then follow with your moisturizer. It layers well with Hyaluronic Acid and peptide serums like our Matrixyl 3000 + Argireline Serum. Avoid using copper peptides at the same time as direct Vitamin C or strong acids — alternate them (morning vs. evening) for best results, as they work through different mechanisms.

They work in different ways. Retinol accelerates cell turnover but can cause irritation, peeling and sun sensitivity. Copper peptides (GHK-Cu) support collagen production and skin repair without those side effects, making them a gentler path to firmer, smoother skin — especially for sensitive skin or anyone who can’t tolerate retinol. Some people alternate both for complementary benefits.

Most users notice improved texture and hydration within 4 to 6 weeks of consistent daily use. Visible improvements in firmness and fine lines typically develop over 8 to 12 weeks, since collagen remodeling is gradual. Consistency matters more than frequency — daily use delivers better results than occasional application.

Yes. The formula contains only 6 ingredients and is free of parabens, sulfates, dyes, fragrances and essential oils, making it well-suited to most skin types. If your skin is particularly sensitive or reactive, we recommend patch testing on the neck before applying to your face. For an even gentler option, our Bakuchiol Smoothing Serum is a plant-based retinol alternative designed for sensitive skin.

Absolutely. Copper peptides are one of the most popular anti-aging ingredients for men, because GHK-Cu targets skin elasticity, firmness and overall repair rather than cosmetic concerns alone. The fragrance-free, 6-ingredient formula is easy to add to a simple routine and a great entry point for anyone new to active skincare.
