What is the difference between aesthetic and esthetic?

In international business, understanding the difference between aesthetic and esthetic is crucial. While both terms describe the look or feel of something, the spelling varies based on the country of origin. In the United States, "aesthetic" is the more common term, while "esthetic" is used in countries that use British English. Despite the spelling difference, both words have the same meaning and can be used as a noun or an adjective. In Great Britain, estheticians work in salons and must meet certification and educational requirements, while in the United States, estheticians can begin working after completing certification programs.
