I've noticed that my skin has been breaking out a lot lately. What is the cause?

The most common causes of acne are excess oil production, hormonal changes, and bacterial infections. Excess oil production can be caused by diet, stress, or genetics. Hormonal changes can be caused by puberty, pregnancy, birth control, or certain medications. Bacterial infections can be caused by over-washing your face, not washing properly, using too many products with harsh ingredients, or having clogged pores.
