Pores clog, your immune system freaks out and you get a pimple overnight.

What to Do

When you feel overwhelmingly excited, pop 200 milligrams of ibuprofen.

It’ll help calm inflammation, Dr. Fried says.

Take another dose in six to eight hours, then one more the next day.

But that’s it; chronic use can be dangerous.

The Trigger: Your Hair

OK, it’s not actually your hair.

It’s your hair products, which can block pores.

An oily scalp makes matters worse.

Oil glands feed acne-causing bacteria, which then end up on, say, your forehead.

That may actually be true about pimples.

Bumps of the nonbaby variety.

Get a water softener.

It’s a cinch to install and costs about 30 bucks.

At the gym or your guy’s pad, use premoistened cloths instead of a rinse-off cleanser.

Then gift him a nice razor and a fragrance-free aftershave.

Everyone’s estrogen and progesterone balance is unique and changes throughout her cycle, Dr. Hirsch says.

That means hormonal birth control affects different women in different ways, including bringing on some nasty breakouts.

Ask your gyno for a new pill, Dr. Hirsch advises.

Again, everyone’s different, so experiment.

Give it a few cycles; switching too soon puts you back at square one.
