　前額部は，加齢変化が顕著に現れる部位で，フィラー注入治療のニーズも高いエリアである。一方で注入に伴う副作用も起こりやすく，熟練したテクニックを要する。代表的な症例を示しながら，安全で効果的な注入法について述べる。

　The effects of treatment with a hyaluronic acid injection into the area from the forehead to temple include lifting the entire face up, which makes the face look younger overall. Therefore, treatment for this area is associated with very high post-treatment satisfaction. In the treatment with the injection, it is necessary to take different approaches depending on the target sites: Smile lines, shallow lines, and deep lines （hollow）. In addition, filling in the volume loss in the area from the forehead to temple with fillers can restore the balance of facial expression muscles that had shown an imbalance with a predominance of depressor muscles. The injection requires an adequate knowledge of anatomy and a mature injection technique because this area is prone to adverse reactions. Furthermore, the choice of preparations is also an important factor.
