Cosmetic dermatology is a practice that focuses on the aesthetic rather than the medical aspect of dermatology and seeks to improve appearance instead of treating diseases, according to the American Academy of Dermatology. Examples of cosmetic dermatology treatments include laser surgery, chemical peels, hair transplantation, filler injection and tumescent liposuction.
To become a cosmetic dermatologist, a person needs to successfully complete college, medical school, an internship and a three-year residency program in dermatology, explains the American Academy of Dermatology. As a dermatologist, he can perform dermatopathology as well as medical, surgical and cosmetic dermatology. He may also choose to study further for a fellowship to gain advanced surgical skills.
