En quoi est-ce utile d’apporter du cuivre à l’organisme  par voie cutanée ?

Why is it beneficial to deliver copper to the body through the skin?

Published February 20, 2024, by Maylis, Chemical Engineer — 2 min read

Copper is a vital trace element that needs to be supplied to the body through diet. It contributes to the proper functioning of the body by participating in numerous physiological and metabolic processes. For instance, the presence of copper in tissues aids in the assimilation of another essential mineral, iron. The latter is involved in the formation of red blood cells and also contributes to the maintenance of bone health, blood vessels, nerves, and immune function.

In a healthy individual, 15% of the copper present in their body resides within the skin. Copper contributes to the synthesis and stabilisation of extracellular matrix proteins, such as collagen. It is also essential for wound healing as it promotes angiogenesis (the development of new blood vessels) and thus the regeneration of the skin.

Supplementing the skin with copper through topical application, in addition to dietary intake, is beneficial as it further stimulates the synthesis of the skin's bioactive molecules (collagen and elastin), thereby preventing and/or reducing the appearance of ageing signs (wrinkles and fine lines).

Furthermore, to address skin issues such as enlarged pores and/or the characteristic hyperseborrhea of oily skin, copper, and more specifically its PCA form (I.N.C.I.: Copper PCA), is more relevant for topical application than for ingestion.
