Female stars at home and abroad, led by Big S, are pursuing hyaluronic acid, which has become a life-saving medicine for female stars to continue their youth. In reality, many people are confused because they don't understand the difference between the two when they choose to do wrinkle removal injection. Today, China, South Korea and the United States will briefly introduce the difference between hyaluronic acid and Botox, and provide a reference for everyone when choosing wrinkle-removing injections. Hyaluronic acid (HA) or uronic acid is a linear macromolecular polysaccharide composed of disaccharide units (glucuronic acid -N- ethylthioglucosamine), which is a naturally occurring substance in tissues. It can also lock a large number of water molecules, moisturize and lubricate tissues, and make skin full, young and elastic. Botox is a kind of bacteria that grows in anoxic environment, and it is one of the most toxic toxins at present. Botulinum botulinum is a deadly pathogen, which secretes toxins in the process of reproduction, and it is one of the most toxic protein. 1. The action principle of different hyaluronic acid can be summarized by the word "filling". At present, the high-tech hyaluronic acid used for medical cosmetic injection is very similar to the original hyaluronic acid in human body, and can be gradually absorbed and integrated by human body after refraction. Hyaluronic acid is filled by subcutaneous injection, and concave places can be filled. 2. Learning injection beauty training is suitable for different symptoms. Because of the different action principles, the treatment targets are also different. In wrinkle removal, as long as hyaluronic acid is aimed at static wrinkles, that is, wrinkles that have nothing to do with expressions, such as decrees. On the contrary, Botox mainly targets at dynamic wrinkles, that is, wrinkles that only appear when you make expressions, such as crow's feet, frown lines and head-lifting lines. 3. The effect time after hyaluronic acid injection is different, and the effect of filling wrinkles can generally be seen immediately. After Botox is killed, the effect can be seen in 3~4 days, and it can be completely effective in a week or so. 4. It is also very important to maintain the effect of injection with different duration of action. Hyaluronic acid injection can generally last for 6~ 10 months, depending on the individual's body metabolism. As well as the injection site and the selected molecular size.
