Dermatology is the medical specialty focused on diagnosing and treating conditions related to the skin, hair, and nails. Dermatologists are trained to address a wide range of skin issues, from common problems like acne and eczema to more complex conditions such as skin cancer.

1. Acne: A skin condition characterized by pimples, blackheads, and whiteheads.
2. Eczema (Dermatitis): Inflammation of the skin that can cause redness, itching, and flaking.
3. Psoriasis: A chronic autoimmune condition that leads to the rapid buildup of skin cells, resulting in scaly patches.
4. Skin Cancer: The most common form of cancer, including basal cell carcinoma, squamous cell carcinoma, and melanoma.
5. Rosacea: A chronic skin condition causing facial redness, visible blood vessels, and sometimes pimples.
