There is no such thing as the best way to fill the tear troughs. There are various ways to fill the tear troughs, such as local injections of hyaluronic acid, injections of collagen, autologous fat filling, etc. Different people are suitable for different ways, so we cannot conclude which way is the best. Different people are suitable for different types of fillers, so we can not conclude which filler is the best. 1. Hyaluronic acid injection: Hyaluronic acid is injected into the tear trough area as a filler to plump up the face. This method is safer, and the effect can be maintained for half a year to one year after injection. It is not recommended if you are allergic to hyaluronic acid or during pregnancy. 2. Collagen injection: Collagen is injected into the tear trough to flatten it. Recovery is usually required for about two months after injection. The effect after filling usually lasts for six months to one year. 3. Autologous fat filler: This type of filler is to suck out a small amount of fat from the fatty parts of the body and fill the fat into the tear trough area. The effect of this method is relatively more natural, the absorption rate is higher, the effect can be permanently preserved after filling, but also can prevent the body from rejection after the operation. It is recommended to go to the hospital for professional consultation to choose a more suitable way to fill the tear trough.
