Though many think of dermatology as a purely cosmetic field of medicine, there are a number of serious and debilitating diseases that require top-notch care from dermatologists and clinics that specialize in dermatological (skin) care. Some diseases treated by dermatologists include acne, eczema, rosacea, psoriasis and skin cancer. The best dermatology treatment centers offer top-of-the-line care for these conditions as well as less serious cosmetic issues, such as brown spots and caring for aging skin.
