What is acne vulgaris and how can it be treated?

Serious illness: It's the common pimply / blackhead rash that teens tend to get on the face and elsewhere. It's unrelated to diet, hygiene or lifestyle, and is best managed first with topical benzoyl peroxide as tolerated. If this fails, a visit to your personal physician to add a second rx or a different program is in order. Visible acne nowadays is a grave professional liability to be managed until it remits.
