Cosmetology (whose root is cosmetic) is the study or art of cosmetics and their use. The job of a cosmetologist is to make people beautiful. Cosmology (whose root is cosmos) is the study of the physical universe considered as a totality of phenomena in time and space. Cosmologists consider vast questions such as the origins and trajectory of the universe, the movements of galaxies, and the nature of space-time.

Cosmetology is mainly an American term, but it has begun to work its way into other varieties of English. Cosmology is used throughout the English-speaking world.
