Dermatologist/Cosmetologist

A dermatologist is a medical doctor who specializes in the diagnosis, treatment, and prevention of skin, hair, and nail disorders. They handle conditions such as acne, eczema, psoriasis, and skin cancer, among others. Dermatologists can also perform skin surgeries, including mole removal and biopsies. 

A cosmetologist, on the other hand, is a professional trained in beauty treatments to enhance a person's appearance through various non-medical techniques. They are experts in skin care, Botox treatments, fillers for the face and elsewhere and also any other cosmetic procedures.
