It can be filled by injection ~ that is, filled with hyaluronic acid or aibeifu. Hyaluronic acid is short-lived and will not be metabolized for six months to one year. The price is relatively cheap, and the domestic products are ok, about 3 thousand to 6 thousand.

If you want an injection, ask about the holding time. Chin injection will not change much, and you can't expect too much. It's okay to hit your nose.
