Using oil-based skin products or cosmetics can make acne worse. Acne can run in families. If one of your parents had severe acne, you are more likely to get it too! Symptoms of acne include pimples, whiteheads, and blackheads and can occur on the face, neck, shoulders, back, or chest.
Pimples that are large and deep are called cystic lesions. These can be painful if they get infected. They also can scar the skin. If you have one of these, it is important that you contact a dermatologist right away.
