如果手臂上突然黑了一塊，肯定是會驚恐萬分！百思不得其解時，可別忽略了會產生光敏感反應的食物。皮膚科門診中，就經常有人因為光敏感反應導致皮膚變黑就醫，醫師進一步問診，這才知道原來是吃了或是用了會產生光敏感反應的食物。

**檸檬柑橘芹菜 容易產生光敏感**

你知道會產生光敏感反應的食物有哪些嗎？舉凡檸檬、柑橘、葡萄柚、胡蘿蔔、芹菜、柚子都會使肌膚出現光敏感現象。醫院皮膚科李勇毅醫師表示，門診中經常會有因為光敏感導致皮膚變黑的病人，尤其是因為擠檸檬汁不慎將汁液噴到手臂上，如果沒有清洗乾淨，就很可能因為經由陽光曝曬，而導致手臂變黑。

**光敏感泛應 恐罹皮膚炎、水泡**

李勇毅指出，由於光敏感反應而導致肌膚反黑之外，還有可能會出現皮膚炎及起水泡，甚至有人看到皮膚變黑，還以為是得到癌症，其實只是光敏感反應導致。

**黑色素沈澱 耗時一年才能消褪**

而除了擠檸檬不小心讓汁液噴到手臂，導致手臂反黑之外，竟然還有人因為用檸檬切片敷臉，致使整張臉變黑的案例；李勇毅醫師進一步指出，由於光敏感反應導致的肌膚反黑，是屬於色素沈澱，通常會隨時間而漸漸褪去，不過卻是曠日廢時得耗上一整年的時間。

**塗退斑膏、類固醇 可適時治療**

至於光敏感反應所出現的肌膚反黑，有什麼方法可以治療呢？總不能黑著一張臉度過一整年啊！如果要治療，可以用退斑膏，若是在急性期，有出現水泡，則可用類固醇藥膏治療。所以，李勇毅醫師建議，如果去吃飯時，要擠檸檬，可以用餐巾紙包住再擠，就比較不會讓檸檬汁液噴到手臂上。(李勇毅 -台北長庚紀念醫院皮膚科醫師)
