What is copper peptide?

A peptide is a small chain of amino acids, the building blocks of proteins. It plays an essential role in many biological functions of our body . Copper peptides, for their part, combine the benefits of amino acids with the properties of copper, an essential trace element for our body.

Copper peptides, first used in the treatment of acute wounds

The history of this active ingredient dates back to the discovery of the benefits of copper in wound healing and cell regeneration. Scientists have observed that copper plays an important role in the synthesis of collagen, a key protein for youthful and healthy skin. They are therefore beginning to exploit the regenerating properties of copper by combining it with peptides. This is how copper peptides, designed to promote cell regeneration and improve the appearance of the skin, come into being.

The discovery of the multiple benefits of copper peptides

Over time, scientists continue to explore the properties of this active ingredient. They discover that it brings many benefits to the skin. These benefits go far beyond healing and regeneration. Copper peptides are found to be powerful anti-aging agents . They reduce the appearance of fine lines and wrinkles. They also demonstrate surprising abilities in alleviating skin inflammation. They help the skin protect itself against damage caused by free radicals.

The introduction of copper peptides into facial care

Thanks to their potential and their multiple advantages, copper peptides quickly began to interest professionals in the cosmetic industry. Many skincare brands have integrated these active ingredients into beauty products such as moisturizing creams or serums acting against premature aging. More and more users are turning to copper peptides to improve the appearance and health of their skin.

What is the difference between copper or copper peptide treatment?

Before discovering all the benefits of copper peptides , let's ask ourselves the difference between copper treatment and a product formulated with copper peptides. These two deceptively similar assets have notable differences.

The effects of beauty products containing copper

Copper is found in beauty products in the forms copper PCA or copper gluconate. Copper PCA is recognized for its antibacterial and sebum-regulating properties. It is particularly indicated in the treatment of combination to oily skin. It is an active ingredient also used in treatments for oily hair. Copper gluconate , for its part, is used for its ability to help the skin regenerate and heal. Gluconate allows better assimilation of copper by the skin.

Copper vs copper peptides: which active ingredient for which use?

To benefit from more targeted benefits for your skin, rely on copper peptides. They are designed to penetrate deep into the skin and act directly on the cells. Although copper provides multiple benefits to the skin, it is less bioavailable and less specific than copper peptides. The latter are more elaborate forms of copper . They are better absorbed into the skin and target specific skin concerns more effectively.

The benefits of copper peptides on the skin

Copper peptides act on various skin problems. Anti-aging, healing and regenerating, the benefits are numerous. If you are looking for a complete product, offering visible results on the appearance of the skin , focus on this active ingredient.

Copper peptides improve skin regeneration

Copper peptides are known for their ability to stimulate cell regeneration. They promote the production of collagen and elastin. These two proteins are essential for maintaining skin elasticity and firmness. With regular use, a copper peptide product can help reduce the appearance of fine lines and wrinkles. It visibly restores the vitality of the skin.

An active ingredient that helps heal imperfections

The benefits of copper peptides on wound healing are one of the first discoveries that led to their use in cosmetics. By promoting the formation of new blood vessels and the production of collagen, they accelerate the healing process. Copper peptides are particularly effective in reducing the appearance of scars, marks and skin imperfections according to a study published in 2007 .

Beauty products with soothing and anti-inflammatory effects

Counteracting the damage of free radicals is essential to maintaining healthy, youthful skin. Copper has anti-antioxidant properties. It protects the skin from damage caused by free radicals like premature spots and wrinkles. By protecting the skin from environmental aggressions, copper helps fight against premature aging of the skin.
