A dermatologist is a medical professional specializing in the diagnosis, treatment, and prevention of skin, hair, and nail disorders. Dermatologists are highly trained to manage a wide range of conditions, from common issues such as acne, eczema, and psoriasis to more complex concerns like skin cancer, autoimmune diseases affecting the skin, and cosmetic concerns such as aging signs and scarring.

In addition to treating medical conditions, dermatologists may offer cosmetic dermatology services, such as Botox injections, laser treatments, and chemical peels to enhance a patient's appearance and address aesthetic concerns.

Dermatologists typically undergo extensive education and training, including medical school, a residency in dermatology, and potentially sub-specialization in areas like pediatric dermatology, dermatopathology, or cosmetic dermatology. They use various diagnostic tools such as skin biopsies, imaging, and advanced treatments like phototherapy, cryotherapy, or surgical excisions to manage conditions effectively.
