The Benefits of Copper Peptides For Anti-Aging, Explained

Skincare enthusiasts are always on the lookout for the next anti-aging innovation—any product that can improve skin texture, brighten the complexion, or slow the passage of time. From collagen treatments and vitamin C serums to bakuchiol and retinol, the beauty industry continues to expand its means of addressing early signs of aging. Latest ingredient gaining real momentum? Copper peptides are quickly becoming the leading anti-aging active. Below, we’ll take a clear look at their origins, how they work, and why they’ve become such a coveted addition to our modern day lives.

What are copper peptides?

Peptides naturally produced by the body are chains of amino acids that are the basic building blocks of proteins. Their job is crucial: Like structural “bricks,” they help form proteins like collagen and elastin, which are essential for maintaining skin’s texture, density, and elasticity. Among the billions of peptides estimated to exist, the copper peptide GHK-Cu has generated particular excitement in the field of cosmetic science.

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

Copper Peptide Benefits

Since copper peptides occur naturally in the body, they provide a variety of benefits when applied topically. First discovered in 1973 by Dr. Loren Pickart, the copper peptide GHK-Cu stands out for its excellent anti-aging capabilities. It is known to stimulate collagen synthesis, helping to maintain skin’s firmness and elasticity while slowing visible signs of aging. A 1998 study from Reims Medical School found that after one month of using this peptide, collagen production increased by 70% and retinoic acid increased by 40%. Subsequent studies further illustrated its benefits.

“In skin care, copper peptides help signal the skin to support collagen and elastin production, thereby improving firmness, texture, and the appearance of fine lines and wrinkles,” says Garshick. “They also have antioxidant properties, aid in wound healing, and promote the production of glycosaminoglycans, such as hyaluronic acid, which enhances hydration.”

How to use copper peptide

Incorporating products containing copper peptides into your skin care routine is simple: Start using them every other day and let your skin adjust, then increase frequency based on skin tolerance and visible results.

As for which formula is best, Garshick recommends looking for products that pair copper peptides with barrier-supporting and moisturizing ingredients, “as this helps maximize tolerability and effectiveness.” She particularly likes Mother Science Molecular Genesis Barrier Repair Moisturizer, which combines copper peptides with the brand’s patented ingredients Malassezin, hyaluronic acid, lipids, squalane, and growth factors (“an excellent option for patients looking to improve signs of aging while prioritizing barrier repair and overall skin health,” she says) and DRMTLGY’s needle-free serum, which contains copper peptides, ceramides, niacinamide, and hyaluronic acid.
