The Most Common Causes of Acne
Bacterial Infection

As hinted at, bacteria is another major cause of acne and breakouts. The sebaceous glands produce oils to help coat hair and hair follicles, as well as oil to keep the skin supple. When the oil gets clogged in pores, it can cause a buildup and trap bacteria, which is what can cause little tiny infections that appear as whiteheads or blackheads. In some cases, it can also cause acne nodules. Thankfully, infections involved with acne can be treated with a prescription antibiotic, which can also be paired with another acne treatment ingredient like benzoyl peroxide.
