A dermatologist is a doctor who specializes in the diagnosis and treatment of diseases and conditions that affect the skin, hair and nails. They perform everything from routine preventative care to invasive procedures such as surgery.

They may also perform cosmetic services like dermal fillers, Botox, chemical peels and laser surgery to zap wrinkles and scars from the face and neck. Depending on their training and credentials, some even offer skin cancer screenings.

Dermatologists also work with children and adults who have various skin ailments, including acne, psoriasis and eczema. They are able to identify and treat conditions ranging from a simple cold to a deadly form of cancer called melanoma.

To become a dermatologist, you need to attend medical school and complete a one or two year residency program. As a result, the title of doctor of dermatology can be hard to come by.
