Copper Amino Isolate Serum 3 1:1 (CAIS3) is a lightweight, water-based serum designed to support skin structure and visible skin quality as the skin ages. The formula contains a concentrated 1% blend of GHK-Cu copper peptides and 1% GHK, working in a balanced 1:1 ratio to support elasticity, firmness, and the appearance of smoother skin.

Copper peptides play a central role in maintaining the look of skin resilience by supporting collagen-related processes and reducing the appearance of fine lines. Tripeptide-29 complements this action by supporting the skin’s structural components, helping improve visible texture and skin strength over time.

Plant-derived glycogen supports hydration by helping maintain hyaluronic acid levels, contributing to improved skin smoothness and overall skin comfort. The vivid blue colour reflects the high concentration of copper peptides within the formulation.

With a pH range of 5.7–6.7, this alcohol-free, oil-free, and silicone-free serum suits all skin types and meets vegan, gluten-free, and cruelty-free standards.

Copper Amino Isolate Serum 3 1:1 focuses on precision and potency to support the skin’s natural repair processes. The formula combines 1% GHK with 1% GHK-Cu, bringing together two complementary peptides at equal strength to work in synergy. GHK supports skin repair and renewal, while GHK-Cu reinforces structural integrity and resilience. Using both at this concentration improves copper delivery efficiency, which matters for maintaining skin strength and long-term health. This balanced, high-potency approach helps you support firmer, more resilient skin with improved overall condition.
