Hyaluronic acid is generally an ingredient contained in beauty cosmetics, which has certain maintenance and moisturizing effects. Hyaluronic acid, also known as hyaluronic acid, is a kind of natural polysaccharide, which exists in the dermis of human skin in large quantities and is an important component of skin moisturizing. Hyaluronic acid content will decrease with the increase of age, and will start to lose after the age of 25. At the age of 30, the infant period is 65%, and at the age of 60, it is 25%, which will lead to skin aging, wrinkles, roughness, dullness and uneven skin color due to dryness and lack of water. Therefore, the key to fight wrinkles is to increase the content of hyaluronic acid in the skin and keep it for a long time. Hyaluronic acid's moisturizing effect is 16 times that of collagen, and its water retention value can reach 1000CC/g, so it is now recognized as a better moisturizing product. Advantages of hyaluronic acid injection in wrinkle removal 1. Hyaluronic acid can naturally smooth deep or middle wrinkles, without stiff expression, and it is also very effective for beauty, cheeks, temples, chin and earlobes, and lasts for a long time. 2. Hyaluronic acid has high compatibility. It can be completely decomposed and will not remain in the body. When it decomposes gradually, it can combine with water to replace the decreasing volume until it is completely degraded. This is an important factor that hyaluronic acid will not shrink compared with other products and its effect will last for a long time. 3. The treatment is very safe, not allergic, not exclusive, and the treatment process is simple and fast. The above is Huamei's introduction to the difference between hyaluronic acid and hyaluronic acid. Hyaluronic acid has a small range of action, and hyaluronic acid injection has many plastic and cosmetic effects, and the two effects are different. (Editor: Li Wei)
