Skincare enthusiasts are constantly on the lookout for the next anti-aging breakthrough—anything that pledges to smooth texture, even out tone, or slow the visible signs of time. From collagen treatments and vitamin C serums to bakuchiol and retinol, the beauty world keeps growing its collection of solutions for early aging signs. The newest ingredient making waves? Copper peptides, which are quickly becoming a top age-defying active. Here’s a straightforward guide to their background, how they function, and why they’re now a sought-after part of modern skincare routines.

What are copper peptides?
Peptides, produced naturally by the body, are chains of amino acids—the basic components of proteins. They play a vital role: acting like structural “bricks,” they help build proteins such as collagen and elastin, both key to maintaining skin texture, density, and elasticity. Among the billions of peptides that exist, one called copper peptide GHK-Cu has generated special excitement in cosmetic science.

“Copper peptides are a type of carrier peptide composed of copper bound to amino acids, which are the building blocks of proteins,” explains board-certified dermatologist Dr. Marisa Garshick. “They occur naturally in the body, but their levels decrease as we age.”

The benefits of copper peptides
Because copper peptides are found naturally in the body, they offer a broad range of advantages when applied to the skin. First discovered in 1973 by Dr. Loren Pickart, copper peptide GHK-Cu is notable for its impressive anti-aging abilities. It’s known to boost collagen production, helping maintain skin firmness and resilience while reducing visible aging. A 1998 study from the Reims Faculty of Medicine showed that collagen production rose by 70% after one month of using this peptide—compared to a 40% increase from tretinoin. Later studies have continued to highlight its benefits.

“In skincare, copper peptides help signal the skin to support collagen and elastin production, which can improve firmness, texture, and the look of fine lines and wrinkles,” says Garshick. “They also have antioxidant properties, aid wound healing, and promote the production of glycosaminoglycans like hyaluronic acid, which boosts hydration.”

How to use copper peptides
Adding copper peptide products to your skincare routine is easy: start by applying them every other day to let your skin adjust, then gradually increase frequency based on your skin’s tolerance and the results you see.

As for the best formulations, Garshick suggests choosing products that combine copper peptides with ingredients that support the skin barrier and provide hydration, “as this helps maximize both tolerability and results.” She particularly recommends the Mother Science Molecular Genesis Barrier Repair Moisturizer, which blends copper peptides with the brand’s patented ingredient Malassezin, along with hyaluronic acid, lipids, squalane, and growth factors (“It’s an excellent choice for anyone wanting to address signs of aging while also focusing on barrier repair and overall skin health,” she notes) and DRMTLGY’s Needle-less Serum, which contains copper peptides, ceramides, niacinamide, and hyaluronic acid.
