Cosmetic products containing precious metals - gold and silver - are in constant demand and arouse great interest. And this is easily understandable, since gold has always attracted people. However, for the cells of our skin, the most valuable is a much more modest metal - copper. However, for all its value, copper at the same time harbors hidden dangers, which you should also be aware of before including this metal in cosmetic products.

<h2>Copper and enzymes</h2>

Copper is one of the main elements, the chemical properties of which have enabled the very existence of living organisms. Copper in the human body exists in two states - Cu1+ (monovalent) and Cu2+ (divalent). Thanks to this, it can participate in many oxidation-reduction processes necessary for the vital activity of the body.

Copper deficiency in the skin and its consequences

The most obvious symptom of a lack of copper in the skin is a violation of collagen synthesis.

Another important consequence of copper deficiency in the skin is the disruption of the important antioxidant enzyme - superoxide dismutase (SOD). The main function of this enzyme is the neutralization of the most dangerous of free oxygen radicals - the superoxide anion radical, which, in particular, is formed in the skin under the influence of UV radiation and to a large extent causes most of the damaging effects of solar radiation.

A lack of copper in the skin also leads to an increase in the reaction of non-enzymatic glycosylation of proteins. In the course of this reaction, proteins such as collagen and elastin spontaneously bond with sugars, losing their elasticity and firmness.
