What causes body acne and how can it be managed?

Body acne on chest, back and shoulders can be linked to genetic predisposition, excessive sweating and untreated scalp conditions such as dandruff, dermatologists say. Using prescribed body washes, showering after sweating and avoiding tight, non-breathable fabrics may help prevent flare-ups. Experts also caution against skipping moisturiser, as this can damage skin barrier and worsen breakouts.
