劉逸鳴醫師的部落格

常聽身邊的朋友說”走啊，我們去打肉毒”，這是不正確的，其實真正打到臉上、真正有作用的是肉毒桿菌毒素。其實肉毒桿菌毒素(Botulinum Toxin)是由肉毒桿菌(Clostridium botulinum)所分泌的一種蛋白質，可分為A, B, C, D, E, F, G等七型，臨床上主要使用A, B型。此物質會阻斷神經末梢釋放乙醯膽鹼(acetylcholine)，阻斷神經與肌肉的信號傳遞，肌肉也就無法收縮啦!!以前醫生就是利用這個原理去治療斜視、中風後的肌肉經癴、偏頭痛、斜頸等病症，但現在醫美盛行、肉毒就被拿來打到臉部的肌肉、藉此改善臉部動態的紋路；另外肉毒桿菌素也能阻斷神經與汗腺的信號傳遞，改善手汗的症狀；也能減少頂漿腺(apocrine glands)的分泌，改善狐臭。
