The diseases a dermatologist might treat are: acne (a condition caused by blocked skin follicles - a condition experienced by many teens and young adults), eczema (dry, itchy skin), basal cell carcinoma (the most common type of skin cancer) , psoriasis (causes red, scaly skin), rosacea (causes redden skin and pimples), scleroderma (causes tight, hard skin), vitiligo  (causes patches of skin to go white, and athletes foot (a fungus that causes dry, itchy, peeling skin, blisters, and bleeding). 

Skin diseases can be caused by a number of things: (bacteria, fungus, or parasites), (contact with allergens or another person's skin), (genetics), (medication), (sun exposure), (conditions that affect your thyroid, kidneys, or immune system).

Because I have the skin type of a typical ginger despite only being a daywalker, I have to see a dermatologist once a year to check for skin cancer.
