Hyaluronic acid is a transparent natural polysaccharide colloidal crystal that is abundantly present in human connective tissue and dermis. The most important thing for the human body to maintain its moisture content is hyaluronic acid. It is a moisturizing factor for the skin. It has a powerful moisturizing function, making hyaluronic acid a hot ingredient. Hyaluronic acid molecules can carry more than five hundred times more water than collagen molecules can carry 30 times more water, so hyaluronic acid plays an important role in the human body. Hyaluronic acid is present in the skin. Appropriate supplementation of hyaluronic acid can not only help the skin absorb a lot of water from the body and the surface of the skin, but also enhance the skin's long-term water retention capacity. When hyaluronic acid absorbs a large amount of water, the elastic fiber and collagen are in a water-filled environment, and the skin is more elastic. Young skin is rich in hyaluronic acid, so it is soft and elastic. Hyaluronic acid begins to lose after the age of 25, leaving only 65% of the infancy at the age of 30, and only 25% at the age of 60. Hyaluronic acid will be lost with age, causing the skin to lose water and lose its elasticity and luster. The skin will appear wrinkled and aging after a long time. Hyaluronic acid was approved by the FDA in December 2003. It has been widely used in the filling of the law, wrinkles, tears, and wrinkles in the eyebrows. It can also be used in the nose, nose, blusher, chin, youth. Acne and chickenpox concavity correction.
