Final answer:
Option 2). An esthetician is a cosmetologist specialized in skin care, providing cosmetic treatments like facials, not to be confused with dermatologists, who are medical doctors with expertise in skin disorders.
Step-by-step explanation:
An esthetician is a cosmetologist with a focus on skin care. Professionals with training in facials, skin analysis, and other body treatments, estheticians handle skin cosmetically. They do not have a medical degree, thus they cannot diagnose skin disorders, write prescriptions for drugs, or do surgery, unlike dermatologists. Dermatologists are medical professionals that specialize in treating skin conditions. They can also carry out aesthetic procedures like laser and Botox treatments. Plastic surgeons are experts in reconstructive or cosmetic surgery, which does not mainly focus on skincare but may involve the skin. Professionals who apply makeup to improve or change a person's appearance are known as makeup artists; they do not have training in treating skin conditions.
