cosmetologist（n.）
"化妆品专家"，1925年，美国英语，出现在州法规中规定该职业，源自 cosmetology + -ist。更早的词是 cosmetician（1914年）。
The manufacturers of cosmetics have a new friend in the shape of a New Yorker, who calls himself a complexionist and prescribes a mixture of sulphur and glycerine to be rubbed on the face every night and washed off in the morning with ammonia. An elephant might not suffer from this treatment, but a human being who attempts it may reckon on about a year of repentance for every week of rubbing. The regular physicians might do a worse thing than expose the shameful ignorance of this "complexionist." [Ladies' Home Journal, August 1888]
化妆品制造商有了一个新朋友，他是一位纽约人，自称为“肤色专家”，并建议每晚涂抹一种硫磺和甘油混合物，早上用氨水洗掉。大象可能不会因这种治疗而受苦，但试图这样做的人可能会为每周的擦拭而悔恨一年。常规医生可能会做得比揭露这位“肤色专家”的可耻无知更糟糕。[《女士家庭杂志》，1888年8月]
