Acne is a skin disorder that leads to an outbreak of lesions called pimples or "zits."
Stress causes zits, there's no doubt.
Even when you try new makeup, you might not see resulting zits for two whole weeks.
You might think there will be no more zits and no more nightly applications of smelly products.
According to the website Holistic Online, acne is the scientific term for what many usually refer to as zits, pimples, blackheads, whiteheads, and other nasty irritants that camp out in the skin.
