Dermatology is a field of medicine that deals with the skin. There are different types of skin disease, from eczema to skin cancer. In dermatology a doctor will have to determine what the skin disease is and then decide on a course of treatment. For patients with eczema often a cream is offered to clear up the severely dry skin. Dermatology also includes rosacea, which is where the skin can be extremely red and have a lot of pimples.

Dermatology can help treat skin cancer. Those in dermatology look for radiation, chemotherapy, or other medicines that will help reduce the effect of skin cancer. Doctors will see the patients, but others in dermatology may be at the research end finding new and helpful products.
