Hello, I'm glad to answer this question for you. Filling the forehead with hyaluronic acid can not only make the forehead plump, but also reduce the forehead lines to some extent. After filling, the shape is natural, there is no need for postoperative rest, and the injection wound is small. The price is generally 4000- 10000. It is recommended to go to a regular hospital. I hope my answer is helpful to you. Thank you.
