Hyaluronic acid, also known as glyoxylic acid and hyaluronic acid, is a natural polysaccharide and an important ingredient for moisturizing the dermis of human skin, its content decreases with age, resulting in dry and dehydrated skin, wrinkles, roughness and uneven skin tone. Hyaluronic acid not only has the function of maintaining skin elasticity, but also locks a large number of water molecules and has a moisturizing and lubricating effect on tissues. What is the role of hyaluronic acid? Water is the fountain of life, the aging body will gradually lose water, the most important substance for human tissue to keep water is hyaluronic acid. The amount of hyaluronic acid in the human body will decrease with age, thus causing dry skin and wrinkles. Hyaluronic acid is the first step in skin care, and the water content of healthy skin should be maintained at about 15-20%. The moisturizing effect of hyaluronic acid is 16 times that of collagen, and the water retention value can reach 1000cc/g. It is the best moisturizing product recognized in the literature today, and because hyaluronic acid can maintain the skin in a healthy state for a long time, it is called the “best moisturizing factor”. The skin itself contains hyaluronic acid, and it exists in the human dermis in a gel form to help maintain moisture and tension and increase the volume of the skin. In addition to the abundance of collagen and elastin fibers, young skin must contain enough hyaluronic acid. As we age, these good ingredients will gradually be lost, causing the skin to lose moisture, lose elasticity and luster, and the appearance of increased wrinkles and sagging skin, however, all the above-mentioned problems are the main causes of aging. How does hyaluronic acid achieve the purpose of making people beautiful? Hyaluronic acid is injected into the human skin to increase the moisture, volume and elasticity of the skin, which can fill the depressions, remove wrinkles and sculpt the appearance.
