What you can do differently: Make sure all the skin care products you're using are labeled "noncomedogenic," which means your makeup or skin care has been specifically formulated not to clog your pores. That said, even if the product is "noncomedogenic," if you're using it continuously and your breakouts continue to get worse, make an appointment with your dermatologist, as you could be allergic to another ingredient in the product that is causing your issues.
Avoid touching or rubbing your face, since that can make acne worse. Try to keep your cell phone from touching your face, too. Use earbuds instead of having the phone against your skin. Also, don't lean your face on your hands, which may carry oils and germs that can irritate blemishes. Sweat can also make acne worse. Sweaty after exercise? Wash up.
Acne (acne vulgaris, common acne) is a disease of the hair follicles of the face, chest, and back that affects almost all teenagers during puberty -- the only exception being members of a few primitive Neolithic tribes living in isolation. It is not caused by bacteria, although bacteria play a role in its development. It is not unusual for some women to develop acne in their mid- to late-20s.
