A master esthetician provides beauty products and esthetics advice and treatments to their clients. As a master esthetician, you offer numerous basic and advanced medical treatments for men and women that will help improve or maintain skin health. You may work in a variety of settings, such as at a medical aesthetician facility, a beauty spa, resorts, or even at a client’s home. Your duties include performing facial cleanses and other beauty procedures to make your clients feel good about their appearance and health. Unlike a cosmetologist, who is also skilled in skin and nail care, your job is to provide skin care exclusively.
