　　減少皺紋

　　Frozen foreheads barely raise eyebrows these days, but there was once a time when injecting a toxin produced by bacteria into one’s face would have been considered odd.

Botulinum toxin injections work by weakening or paralyzing certain muscles or by blocking certain nerves, reducing the appearance of wrinkles。

　　現在，整得僵硬麻木的額頭只會引人側目，但在以前，把細菌產生的毒素注入一個人的臉會被認為不可思議。2002年，肉毒桿菌被批準可用于美容用途，直到那時，肉毒桿菌的趨勢才被越來越多的人接受。肉毒桿菌注射通過削弱或麻痹特定的肌肉或者阻塞特定神經來減少皺紋。
