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.

Thanks to its ability to access the deepest layers of the skin, fast, persistent, and visible results are achieved. For this reason, they have become one of the favorite cosmetic products and you can find them with a creamy or serum appearance.

2-Azelaic acid. It comes from wheat, barley, and rye.

3- Retinoic acid. It is a perfect regenerating acid for combination and acne-prone skin, as it controls oil production, tones facial skin, and reduces pore size for a smooth, soft appearance.
