Dermatology is a branch of medicine that focuses on the study, diagnosis, and treatment of conditions related to the skin, hair, nails, and mucous membranes. Dermatologists are medical professionals specialized in managing a wide range of dermatological issues, including but not limited to skin infections, allergies, dermatitis, psoriasis, acne, and skin cancers. They employ various diagnostic tools and treatment modalities, such as topical and systemic medications, surgical procedures, and cosmetic interventions, to address both medical and aesthetic concerns associated with the skin. Dermatology plays a crucial role in maintaining skin health and treating disorders that impact the largest organ of the human body.
