Breaking out with pimples on your cheeks is usually caused by your skin's oil glands overreacting to hormonal responses, which can be triggered by factors such as stress, eating too much sugar or dairy.
Pimples popping up on your lower cheek, jawline, and chin are known as a “hormonal pattern.”
To help prevent pimples from breaking out on your cheeks be sure to wash your cheeks and your face twice a day with warm water, using a mild cleanser, which works like soap to clean your skin, but is gentler so it doesn't dry it out.
You can also use apple cider vinegar or toothpaste to help get rid of the pimples on your cheeks and anywhere else.
