Featured: Acne (Pimples) Main Article

Acne is a localized skin inflammation as a result of overactivity of oil glands at the base of hair follicles. This inflammation, depending on its location, can take the form of a superficial pustule (contains pus), a pimple, a deeper cyst, congested pores, whiteheads, or blackheads. Treatments vary depending on the severity of the acne.
