Dermatology is the branch of medicine that deals with the diagnosis and treatment of skin disorders.

Understanding the symptoms, risks, and treatment options for various skin diseases is crucial for maintaining skin health.

Common skin diseases include:

1. Acne: A common skin condition that occurs when hair follicles become clogged with oil and dead skin cells, leading to pimples and blackheads.

2. Eczema: A chronic skin condition characterized by red, itchy, and inflamed skin.

3. Psoriasis: An autoimmune disease that causes red, scaly patches on the skin.

4. Skin Cancer: The abnormal growth of skin cells, often caused by exposure to ultraviolet radiation from the sun.
