Speaking of which, girls who love beauty should not be unfamiliar, because lotions, essences, lotions, creams and other skin care products often contain hyaluronic acid, and it is also a popular item in medical beauty. So what exactly is hyaluronic acid?

This may be the confusion of many girls. Why is there no hyaluronic acid in the ingredient list of skin care products that claim to contain hyaluronic acid? In fact, hyaluronic acid is just our daily common name, its scientific name is hyaluronic acid (Hyaluronic Acid), and it also appears in the name of hyaluronic acid (sodium) in the ingredient list. Sodium hyaluronate is the sodium salt form of hyaluronic acid, which has relatively stable properties and is commonly used in practice.

What are the physiological functions of hyaluronic acid?

As a natural substance in our body, hyaluronic acid plays an important role in maintaining the normal function of the human body and delaying the aging process. Hyaluronic acid has various physiological functions such as moisturizing, lubricating joints, regulating cell proliferation and differentiation and migration, promoting wound healing, and anti-oxidation.

Among them, moisturizing is one of the most important physiological functions of hyaluronic acid. Hyaluronic acid has a strong water retention effect in the extracellular matrix, and forms an extracellular gel-like matrix containing a lot of water together with collagen and elastin, making the skin supple and elastic. As we age, the amount of hyaluronic acid in our body decreases. The reduction of hyaluronic acid in the skin will reduce the moisture content between the cells and cells of the skin tissue, the space filled by the gel-like matrix mainly composed of hyaluronic acid will decrease, resulting in tight cell arrangement, collagen loss and hardening, and the skin will It becomes rough, loses elasticity and develops wrinkles.

Antioxidant – UV exposure to the skin will generate oxygen free radicals, excess reactive oxygen species in the body will damage proteins, lipids and DNA, while hyaluronic acid can eliminate free radicals and protect cells from the effects of reactive oxygen species
