Cosmetic acids act exfoliatingly on the skin, stimulating collagen production and achieving constant cell renewal. These compounds are widely used in cosmetics, especially to control the signs of aging, hydrate the skin and improve its elasticity. Many of the cosmetic acids are obtained from the bark of trees, fungi, fruits, and other foods, and have beneficial properties for the health of the skin.
How cosmetic acids act on the skin
Cosmetic acids usually act directly on the dermal and epidermal levels. When applied to the skin, they exfoliate cells, remove old or dead cells, and give the skin a better appearance. These acids are capable of penetrating the skin, causing an anti-aging effect with the production of mucopolysaccharides and collagen. Additionally, they manage to increase the thickness of the dermal layer.
On the other hand, with cosmetic acids, the skin will appear more hydrated, with greater elasticity and a better tone, in addition to the visible reduction of spots and imperfections.
