This beauty secret will surprise you: copper, your new ally!
Copper, a trace element essential for the proper functioning of the body, is also a valuable ingredient in cosmetics. Naturally present in the human body, it is well tolerated by all skin types. Let's take a closer look at the many benefits of copper for our skin.
Copper: A Shield Against Oxidative Stress
Oxidative stress, exacerbated by exposure to pollution, UV rays, and other external aggressions, generates free radicals that are harmful to skin cells. Copper has antioxidant properties that protect these cells by stimulating the activity of superoxide dismutase (SOD), an enzyme that neutralizes free radicals. Copper thus helps slow down skin slackening and the appearance of wrinkles, phenomena linked to oxidative stress.
Flexibility and Elasticity: The Essential Role of Copper
Copper acts as a cofactor for lysyl oxidase, an enzyme essential for the formation of collagen and elastin. In addition, it activates fibroblasts, the cells in the dermis responsible for synthesizing these structural proteins. Thanks to these mechanisms, copper is a valuable ally in preventing skin slackening.
Regulation of Combination to Oily Skin
In the form of PCA copper (copper salt of pyrrolidone carboxylic acid), this trace element is known for its antibacterial and sebum-regulating properties. It is often included in skincare products designed for combination to oily skin prone to blemishes. Copper PCA combats excess sebum production and bacterial proliferation, thereby preventing clogged pores.
Anti-Inflammatory Action of Copper
Certain copper peptides have anti-inflammatory properties. They inhibit the release of tumor necrosis factor TNF-α, a pro-inflammatory molecule that exacerbates inflammation. By reducing this release, copper peptides soothe the skin and protect it from inflammation.
Accelerated Healing
Copper gluconate is beneficial for damaged or healing skin. It activates collagen and glycosaminoglycan synthesis by fibroblasts, a process essential for the formation of new tissue. In addition, copper stimulates angiogenesis, i.e., the formation of new blood vessels, thereby improving the distribution of nutrients, oxygen, and growth factors necessary for healing.
Copper in Cosmetics: How to Use It?
Topical application
Copper is mainly used in serums, creams, or cleansing gels. Depending on its form, it targets specific needs:
- PCA copper : ideal for oily skin prone to blemishes.
- Copper peptides : recommended for preventing skin aging and regenerating the skin.
- Copper gluconate : used for its healing properties.
Combination with other assets
Copper can be combined with other ingredients to enhance its effectiveness:
- Hyaluronic acid : for intense hydration and a plumping effect.
- Zinc : for enhanced action against excess sebum and blemishes.
- Niacinamide : to soothe redness and protect the skin from oxidative stress.
