This element is present in the human body, in the tissues and fluids of the body, it is useful for lubricating and protecting the joints. It is also known as Hyaluronic Sodium. The skin is the most important reservoir of hyaluronic acid. It is present in the dermis and epidermis as well as in many living organisms. Initially, it was extracted from the ridges of roosters, bull's eye or shark skin, the molecule is now obtained mainly by biotechnology or by the fermentation of yeasts and is used in various treatments. The hyaluronic acid obtained is a very faithful copy of the element naturally present in the human body.

Essential to maintaining the structure of the layers of the skin, hyaluronic acid complements the role of collagen. It is thanks to collagen that the skin is firm, and thanks to HA (hyaluronic acid) that the collagen is nourished and hydrated. Hyaluronic acid is intended to hydrate and protect the skin from external aggressions. This product has tremendous elasticity capabilities. Very rich in water, it fills the space between the skin cells. This acid is able to retain up to a thousand times its weight in water, which gives it a strong moisturizing power, the skin is softer, smoother and more elastic. HA offers a double action, it limits water loss and retains water to gradually release it. It is well tolerated by the skin of the face, even by the most sensitive skin.

This element naturally present in the body sees its stock decrease as age increases. A fifty-year-old person has only 50% of their initial stock of hyaluronic acid left, which explains the appearance of fine lines and wrinkles or sagging skin. To maintain beautiful skin and keep the epidermis less marked, products containing hyaluronic acid help the skin to regenerate, moisturizers are beneficial. The action of hyaluronic acid is recommended to reduce dehydration of the skin and the appearance of wrinkles.
