Acne Cosmetica
Acne Cosmetica is a mild and relatively common form of acne is caused by cosmetics. Since it's triggered by topical products, it can strike anyone — even people who are not prone to acne. It typically consists of small, itchy or rashy pink bumps on the cheeks, chin and forehead, developing gradually over the course of a few weeks or months. It may persist indefinitely, but usually does not cause scarring. When shopping for make-up and skin products, look for products that are "non-comedogenic." These products are less likely to cause irritation or clogging of the pores.
