Skincare aficionados are always on the lookout for the latest beauty innovation to upgrade their routine and counter the effects of time. Collagen, vitamin C, bakuchiol, retinol… the beauty industry continues to expand its arsenal for addressing early signs of ageing in particular. One of the latest? Copper peptides, which are rapidly emerging as a leading age-defying active.
Vogue’s pick of the best copper peptide serums at a glance:
Below, a look at their origins, how they work, why they’ve become a coveted addition to modern skincare routines and some of the best copper peptide serums to try.
What are copper peptides?
Peptides, which the body naturally produces, are chains of amino acids, the fundamental building blocks of proteins. Their job is essential: like structural “bricks,” they help form proteins such as collagen and elastin, both crucial for maintaining the skin’s texture, density and elasticity. Among the estimated billions of peptides that exist, copper peptide GHK-Cu has inspired particular excitement within cosmetic science.
“Copper peptides are a type of carrier peptide made up of copper bound to amino acids, which are the building blocks of proteins,” explains dermatologist Dr Marisa Garshick. “Copper peptides are found naturally in the body, but their levels decline with age.”
How do copper peptides work?
Because copper peptides occur naturally in the body, they offer a wide array of benefits when applied topically. First identified in 1973 by Dr Loren Pickart, copper peptide GHK-Cu stands out for its remarkable anti-ageing capacity. It is known to stimulate collagen synthesis, helping maintain the skin’s firmness and resilience while slowing visible ageing. A 1998 study from the Reims Faculty of Medicine found that collagen production increased by 70 per cent after one month of applying this peptide, compared with a 40 per cent increase from tretinoin. Subsequent studies have further illustrated its benefits.

FAQs
What are the benefits of copper peptides in skincare?
“In skincare, copper peptides help signal the skin to support collagen and elastin production, which can improve firmness, texture, and the appearance of fine lines and wrinkles,” says Garshick. “They also have antioxidant properties, help support wound healing, and promote the production of glycosaminoglycans such as hyaluronic acid, which enhances hydration.”
How to use copper peptides
Incorporating products with copper peptides into your skincare routine is simple: begin with applications every other day to allow the skin to adjust, then increase frequency as your skin’s tolerance and visible results guide you.
As far as which formulations are best, Garshick recommends looking for products that pair copper peptides with barrier-supporting and hydrating ingredients, “as this helps maximise both tolerability and results.”
