The Science Behind Copper Peptides

Copper peptide occurs naturally in the human body. It has been used for several years in cosmetics for its numerous benefits on the skin : anti-aging action, collagen production, wound healing and even cell regeneration. This ingredient is recognizable by the beautiful natural blue color that it gives to the product based on natural peptides.

How does copper peptide work on the skin? Explanations

A peptide is simply a sequence of amino acids. There are many skincare ingredients from the peptide family, but they are not all equally effective in cosmetic products. Copper peptide is one of the only peptides to be the subject of several scientific studies that extol its merits in the field of beauty. Here are some of the results observed.

Collagen production

According to laboratory studies, copper peptide stimulates the production of collagen , which is the most abundant protein in the skin. It is what allows you to have firm skin . It is also at the origin of the production of elastin, a protein responsible for the elasticity of the skin , as well as glycosaminoglycans, the best known of which is simply hyaluronic acid.

The copper peptide is therefore what we call a signal peptide : it triggers a signaling cascade within our cells to stimulate the production of essential skin elements.

Reduction of signs of aging

These effects have also been observed in studies carried out on men. Researchers observed a decrease in the visible signs of skin aging , an increase in the density and thickness of the epidermis, as well as the dermis. Copper peptides can also significantly improve skin elasticity and hydration .

Skin healing

But the copper peptide differs from other signal peptides because it also acts as a transporter peptide: it transports copper. Copper is an important element in healing and scarring the skin . Copper peptide can also be of interest for skin prone to inflammatory problems, such as rosacea or acne, because it improves the appearance of imperfections.

In summary, copper peptide is a formidable anti-aging ingredient . It is therefore aimed at all those looking for less visible wrinkles, firmer, more elastic skin, but it is also very effective for healing and tissue regeneration .

The benefits of copper peptide: is it more effective than vitamin C and retinol?

One study compared the effectiveness of copper peptides in skincare products with that of vitamin C and retinol, which are also two major anti-aging ingredients in cosmetics. In this study carried out on men, the researchers observed the following results: after 1 month of use, the copper peptide increased the production of collagen in 70% of the people who used it compared to only 50% for vitamin C. and 40% for those who applied retinol.

Thus, products based on copper peptide represent a new possible way to target the signs of aging thanks to the synthesis of collagen. And what makes it particularly interesting is that unlike retinol or vitamin C, it is an ingredient very well tolerated by the skin in a daily routine, without side effects. It is therefore ideal for people with dry skin or combination skin lacking collagen, but it is also suitable for sensitive skin.

Nooance Youth Serum: essential for your skincare routine

At Nooance, copper peptide is present at 2% in 3 different forms in the youth serum . In addition, to maximize the effectiveness of this product, we also find a concentration of anti-aging peptides of 21% acting in a very different way on the skin: all signs of aging are targeted.


This peptide serum allows you to find younger , firmer skin and a more radiant complexion with notably less redness. This peptide complex is effective in reducing the appearance of wrinkles , including expression lines.

This serum has a double advantage : in addition to benefiting from the effects of peptides, it is a moisturizing and soothing treatment for the skin. Its ingredients include hyaluronic acid, panthenol which is provitamin B5, glucans, which are polysaccharides, and prebiotics to maintain the balance of the skin microbiome.

To use it, simply apply it morning and/or evening to cleansed skin by pouring a few drops into the palm of your hand. Then, with the palm of your hand, apply it to the entire face, neck and décolleté, avoiding the eye area. This anti-aging serum is suitable for all skin types thanks to its light texture.
