I believe there is a mistake in the user interface section. They use the word "esthetics" when they mean aesthetics which is > a set of principles underlying and guiding the work of a particular artist or artistic movement.

The root of the word is possibly Germananic (in German: Ästhetisch) or Greek Aisthetikos. It's not clear that there is a difference from any citable source, however deductive reasoning suggests that escetics is concerned with cosmetology and estheticians. The argument to be made that its the Latin dipthong AE is simplified to E is not valid in this case as inspection of Greek shows.

Edit: update. One given definition of esthetics is > relating to, involving, or concerned with pure emotion and sensation as opposed to pure intellectuality. [dictionary.com]
