What are copper peptides?

The internet’s been asking and skincare gurus everywhere sing their praises endlessly—but why?

For those of us who love to know what goes into our food, hair care, household cleaners, detergents and skincare, etc. we NEED to know, and the answer is a bit more complicated than a quick google search. On the surface copper peptides seem to be this miraculous “cure all” for skincare, but what are copper peptides in skincare and why are they so great?

What are copper peptides in skincare?

Copper peptides, also known as GHK-Cu, are a naturally occurring complex made within the human body during times of repair. As we age our body produces less copper peptides, and your skin and hair cells spend less time in a state of continuous healing. These little wonders were first identified to help heal wounds, and eventually made their way into the skin and hair care segment as a way to repair cells and fight signs of aging.

What do copper peptides do for your skin?

The simple answer: Copper peptides in skincare make your skin plump and bouncy with visibly diminished fine lines. On a deeper level, or epidermis level, copper peptides support the production of collagen and elastin and help repair damaged tissue resulting in tighter, bouncier skin with huge anti-aging benefits. Our natural collagen production decreases year by year as we age, leaving our skin cells less full which creates fine lines and wrinkles over time. Copper peptides help fill those skin cells back up with collagen for bouncy, healthy, youthful-looking skin.

How are copper peptides made?

Copper peptides are naturally-occurring plasma that help repair tissue. The benefits were originally the product of wound-healing because of its reparative properties, before expanding into hair and skincare as we know it today. While only trace amounts can actually be made within the human body, copper peptides are often made in a laboratory setting to generate a higher concentration. At Biossance, our Copper Peptide facial serum is made by our very own in-house lab of scientists. They use a powerful combination of copper peptides, hyaluronic acid, polyglutamic acid and squalane. Each ingredient helps increase the effectiveness of the other within your skin. For example, our vegan-friendly squalane acts as a booster for active ingredients, while copper peptide encourages the production of hyaluronic acid for even more hydration. For this reason copper peptides are often added to ingredients to bolster the effectiveness of other ingredients in skincare and why so many people tout its powerful properties. 

How are copper peptides in skincare different from hyaluronic acid?

Hyaluronic acid is a humectant, or a moisturizing agent used for hydration. Its profound fame comes from its ability to supply skin cells with hydration and to attract water molecules from the air to skin for increased moisture. Copper peptide, as you can see, is known mostly for its anti-aging benefits. When these two ingredients combine they help increase the effectiveness of the other within the skin, resulting in hydrated, plump, bouncy skin with diminished appearance of fine lines and wrinkles.

How do you layer copper peptides into your skincare routine?

If you’ve seen all your favorite influencers touting copper peptides, read this blog, and now feel like this is the ingredient for you, you’re probably asking yourself how to incorporate it into your skincare routine. Like most products, there are beneficial do’s and don’ts to boost performance and avoid unwanted effects. If you’re ready to try Squalane + Copper Peptide Rapid Plumping Serum, here’s what you need to know:



  • Avoid alpha hydroxy acids (aka AHAs), often found in glycolic acid, which can reduce the effect of copper peptides on the skin
  • Avoid vitamin C or L-Ascorbic in the same routine as copper peptides, which can also reduce the effectiveness of copper peptides
