"美容师" 英语可以翻译为 "beautician"。

这个词源于拉丁文的 "facio",意思是 "to make, to do"。后来在英语中加入了 "beauty" 这个词,就成了 "beautician" 这个词,意思是 "a person who is trained in the care and beautification of the skin, hair, and nails",即 "一个接受过皮肤、头发和指甲护理美容培训的人"。

一些英文例句及其中文翻译如下:

She's a beautician at a spa. (她是一家水疗中心的美容师。)
I go to the beautician once a month to get my hair and nails done. (我每个月都去美容院让人给我理发和修指甲。)
The beautician gave me a facial and appped some moisturizer to my skin. (美容师给我做了一次面部护理,并在我的皮肤上涂了润肤霜。)
