Do you know the ingredients of cosmetics? Do you know hyaluronic acid?

Time is a pig killer. As you get older, you will know that women are most afraid of the growth of age. Once they grow, their abilities will decline, and the speed of aging will increase, which will lead to the decline of women's appearance, wrinkles, spots, etc. Therefore, many women will start to take care of themselves when they are young. Hyaluronic acid is the most common anti-aging substance. It can be found in many maintenance products. Do you know it?

Hyaluronic acid, also known as hyaluronic acid, has a molecular formula of (C14H21NO11) n, CAS: 9067-32-7, and is a white powder. It is the main component of connective tissues such as human interstitial tissue, vitreous body, joint synovial fluid, etc. It plays an important physiological role in the body in water conservation, maintaining extracellular space, regulating osmotic pressure, smoothing, and promoting cell repair. Hyaluronic acid has unique physical and chemical properties and physiological functions, and is widely used in medicine.

Hyaluronic acid originally exists in the skin, which can help the skin absorb water from the body and the skin surface, and also enhance the skin's long-term water retention capacity. When hyaluronic acid absorbs water, it makes elastic fibers and collagen in a moist environment, so the skin has elasticity. However, the hyaluronic acid in the skin starts to lose from the age of 25. At the age of 30, only 65% of the skin is left in childhood, and at the age of 60, only 25% is left. The water in the skin will also lose with hyaluronic acid, losing elasticity and luster, and wrinkles will age over time.

Hyaluronic acid has been widely known for its moisturizing properties, Anti-Aging and anti-aging properties, but in fact, many functions are unknown to the public, and the effects of different hyaluronic acids are related to their different molecular weights and structures. According to the molecular weight, hyaluronic acid can be roughly divided into macromolecular, middle molecular, small molecular and micromolecular hyaluronic acid. Most cosmetics use large and medium molecules.
