It is said that women are made of water. In real life, we can have hydrated and tender skin just by drinking water. I believe many beauty-loving ladies are familiar with hyaluronic acid. It also has another name called hyaluronic acid. We all know that it is very effective in moisturizing, and it is found in our general cosmetics, but what are its specific effects and what ingredients does it consist of? We can learn about it in detail. One ingredient Hyaluronic acid is an acidic mucopolysaccharide. In 1934, Meyer, a professor of ophthalmology at Columbia University in the United States, and others first separated the substance from the vitreous body of bovine eyes. With its unique molecular structure and physical and chemical properties, hyaluronic acid displays many important physiological functions in the body, such as lubricating joints, regulating the permeability of blood vessel walls, regulating the diffusion and movement of proteins, water and electrolytes, and promoting wound healing. More importantly, hyaluronic acid has a special water-retaining effect. It is the best moisturizing substance found in nature so far. It is called the ideal natural moisturizing factor (NMF. For example, a 2% pure hyaluronic acid aqueous solution can firmly retain 98% of water. Hyaluronic acid is a multifunctional matrix. Hyaluronic acid (hyaluronic acid) HA is widely distributed in various parts of the human body. The skin also contains a large amount of hyaluronic acid. The maturation and aging process of human skin also changes with the content and metabolism of hyaluronic acid. It can improve the skin's nutritional metabolism, make the skin soft, smooth, remove wrinkles, increase elasticity, and prevent aging. While moisturizing, it is also a good transdermal absorption promoter. Used in combination with other nutrients, it can achieve a more ideal effect in promoting nutrient absorption. Second effect Large molecule hyaluronic acid can form a breathable film on the skin surface, making the skin smooth and moisturized, and can block the invasion of foreign bacteria, dust, and ultraviolet rays to protect the skin from damage; small molecule hyaluronic acid can penetrate into the dermis, slightly dilate capillaries, increase blood circulation, improve intermediate metabolism, and promote skin nutrient absorption. It has a strong anti-wrinkle function, can increase skin elasticity, and delay skin aging. Hyaluronic acid can also promote the proliferation and differentiation of epidermal cells, scavenge oxygen free radicals, and prevent and repair skin damage. The aqueous solution of hyaluronic acid has a very high viscosity and can thicken the water phase; the paste after emulsification with the oil phase is uniform and smooth and has a stable emulsification effect. Hyaluronic acid is the best natural moisturizing ingredient for high-end cosmetics. It has good compatibility and can be added to almost any beauty cosmetics. |
