In a week or so, hyaluronic acid will be mainly used in the field of medical beauty, which is likely to replace collagen, placenta and Botox. Statistics show that 200 companies produce beauty cosmetics and drugs for arthritis and cataracts. Hyaluronic acid has the characteristics of insolubility, low metabolic rate, high water absorption, high water retention and difficult tissue transfer, so the popular development is to apply hyaluronic acid to soft tissue filling. Hyaluronic acid, a tissue filler for injection, can often get good results when it is used to correct dermal scars left by trauma or acne. The combination of Botox and hyaluronic acid can be used to treat wrinkles around eyes and eyebrows. In addition, hyaluronic acid also plays a certain role in shaping the obvious lip and nose lines or lip and nose chin. However, before deciding the treatment policy, professional consultation must be conducted by qualified plastic or cosmetic surgeons. Some cases are not suitable for injection of hyaluronic acid, such as wrinkles caused by some skin lesions, irregular skin surface is too shallow, and the skin is too loose. Other more suitable treatment methods should be used. Generally speaking, the effect of hyaluronic acid injected into the body is about 6-9 months, but this is related to the different injection sites and personal physique. For example, when used for lip plastic surgery, it can last shorter than other facial parts.
