What is Peptinexia™ Copper Serum?
Peptinexia™ Copper Serum is a copper peptide serum formulated for customers who specifically want a 2% concentration of GHK-Cu. The formula pairs 2% GHK-Cu with 5% niacinamide, 1% ectoin, and 1% hyaluronic acid in a lightweight hydrating serum base.
Why Use It?
Peptinexia™ Copper Serum is designed for customers who want to emphasize GHK-Cu within their skincare routine. The formula supports visible firmness, elasticity, hydration, and skin resilience while maintaining the same niacinamide, ectoin, and hyaluronic acid foundation used across the Peptinexia topical line.
Key Actives
GHK-Cu 2% is a copper-binding peptide studied for its role in skin conditioning, extracellular matrix signaling, fibroblast activity, and processes associated with collagen, elastin, and glycosaminoglycan production. Niacinamide 5% helps support the skin barrier, improve uneven-looking tone, and reduce moisture loss. Ectoin 1% supports hydration and helps protect the skin from environmental stress. Hyaluronic Acid 1% attracts and retains moisture, helping the skin appear plumper, smoother, and more supple.
How It Differs from Repair Serum
Copper Serum and Repair Serum share the same hydrating foundation of niacinamide, ectoin, and 1% hyaluronic acid. Repair Serum combines 1% GHK-Cu with 1% PDRN, while Copper Serum uses 2% GHK-Cu without PDRN. They represent two different formulation approaches rather than different quality levels.
Hydrating and Conditioning Base
In addition to 1% hyaluronic acid, the serum base includes glycerin, panthenol, aloe, rosehip, cucumber, chamomile, and rice extracts. Together, these ingredients help replenish moisture, calm the appearance of dryness, and leave the skin feeling soft and comfortable.
Suggested Use
Apply one to two pumps to clean skin once daily, either morning or evening. Gently smooth over the face and neck and allow the serum to absorb before applying moisturizer or sunscreen. Begin with every-other-day use when introducing it alongside other active skincare products, then increase as desired.
Airless Packaging
Peptinexia™ Copper Serum is supplied in a 15 mL airless pump bottle. The sealed dispensing system helps preserve the peptide-rich formula by limiting exposure to oxygen, environmental contaminants, and repeated contact during use.
