This guide is educational information about skin health — it is not medical advice, diagnosis, or treatment, and it is not a substitute for care from a qualified dermatologist or doctor. It does not diagnose, treat, cure, or prevent any condition. See a dermatologist or doctor about skin that is persistent, painful, spreading, or changing, and get any new, changing, or unusual mole or skin spot checked promptly. Seek urgent care for a rapidly spreading rash, signs of skin infection (spreading redness, warmth, fever), or any severe allergic reaction (swelling of the face, lips, or throat, or trouble breathing); in a medical emergency, call 911.
