Don't pop blemishes. It's tempting, but squeezing blemishes can push infected material deeper into the skin, leading to more swelling and redness, and even scarring. Instead, dab on Bye Bye Blemish Drying Lotion before bedtime or Clarifying Gel for daytime.

Avoid leaning your face on objects that collect sebum and skin residue, like a cell phone. Also, be sure to wash your pillowcase regularly, at least once a week.

Remove your makeup before you go to sleep. When buying makeup, make sure you choose products that say "non–comedogenic" on the label. Throw away old makeup that smells or looks different from when you first bought it.

If you get blemishes on your body, try not to wear tight clothes that don't allow skin to breathe. Remember that headbands and caps often trap dirt and oil, too.

If you wear glasses or sunglasses, make sure you clean them frequently to keep oil from clogging the pores around your eyes and nose.
