Ten cosmetic acids and their benefits for the skin

Hyaluronic, retinoic or citric acid are just three of the cosmetic acids that in recent years have gained special prominence in the world of beauty, to the point of becoming an essential substance in many treatments.

These cosmetic acids, which are already part of the beauty routine of many women, have different properties depending on their concentration. At low concentrations they are moisturizing while, if it increases, they help to eliminate the layer of dead skin cells (peeling), which regenerates it and makes it look brighter and rejuvenated.

This type of acid is also effective in improving sun spots, increasing the quality of elastin fibers and the density of collagen.
