Skin conditions that require visiting a dermatologist include eczema, acne, psoriasis, warts and skin cancer, according to Everyday Health. Other conditions include hair loss, skin infection, severe varicose and spider veins, rosacea, and poison ivy, oak and sumac rash, states Healthgrades.
Eczema and acne that is unresponsive to over-the-counter medication necessitate seeing a dermatologist for proper management. Skin cancer patients require regular treatment by a dermatologist, notes Everyday Health. Hair loss and skin infections have several underlying causes. Examination by a dermatologist determines the underlying cause and the best treatment option. Rosacea and severe varicose and spider veins require specialized treatment such as medication, surgery or laser therapy, notes Healthgrades.
Psoriasis is a chronic skin condition that causes plaques and requires treatment by a dermatologist. Contact from poison ivy, oak or sumac plants causes an itchy and blistering rash. Serious cases of this rash require treatment by a dermatologist using oral medication or prescription creams, says Healthgrades.
