The fancy name a store gives the clerk who works behind the cosmetics counter. Not to be confused with a Cosmetologist/Beautican. For to be a Cosmetologist/Beautican you have to take a 2 yr course in a career school or college and go to State Board and take a written and practical test to obtain your license.

That dumb Cosmetician thinks shes a Cosmetologist just because she works behind the cosmetics counter.
