Move over Vitamin C.

When it comes to skincare, we’re always looking for the next big ingredient that is going to rejuvenate our skin and bring it back to life.

You’ve probably heard of antioxidants in skincare before, such as Vitamin C. Why they’re good for the skin is a bit of a lesson in chemistry.

Antioxidants are a type of compound that slows oxidation (a process that produces free radicals). Free radicals are unstable chemical compounds that need electrons to become stable. If they cannot steal an electron from another atom, they may start stealing them from our cells, which can cause damage to cell components, essentially leading to the appearance of ageing (wrinkles, sagging, age spots) and other skin concerns (dullness, dryness and more).

So, antioxidants are often found in skincare due to their use in slowing down this process over time.

There are a lot of types of antioxidants that can be used on the skin, one of which are copper peptides.

What Is Copper Peptide Serum?

Copper peptides work as both an antioxidant and a peptide (a chain of amino acids, which are the building blocks of protein).

The peptides work to replenish the amino acids in the skin, which are the building blocks of the main structural protein in skin, collagen.

A 2018 study published in the International Journal of Molecular Sciences concluded, “GHK [human copper-binding peptide GHK-Cu] is a safe, inexpensive, extensively studied compound that has a wealth of positive and health-promoting effects in many tissues and systems.

“It has been widely used in anti-aging and cosmetic products in humans for decades without any adverse effects, and can be easily incorporated in creams, liposomes, dermal patches or delivered through microneedles.”

Of course, you need to make sure that the products you use have effective concentrations and formulations, but it is exciting new research into skincare that reduces the appearance of fine lines and wrinkles.

What Are The Benefits Of Copper Peptide Serum?

Copper peptides are a powerful antioxidant. Antioxidants help to slow the effects of free radicals on the skin, aiming to reduce the appearance of fine lines and wrinkles.

In the same way, the peptide complex is designed to replenish the amino acids in the skin. Amino acids are the building blocks of collagen.

Some people prefer copper peptides as an alternative to vitamin C should their skin be sensitive to it.

What Should You Not Layer With Copper Peptides?

Try to avoid layering copper peptides with other forms of active skincare, such as Vitamin C, chemical exfoliants (AHAs, BHAs, PHAs) and retinols.

Can You Put Moisturiser Over Copper Peptides?

It should be fine to use a neutral moisturizer on top of your copper peptides.
