Not a fan of scars.

I have acne scars on my face from popping zits. How can I get rid of them?

You've learned the hard way that picking pimples can leave small scars or even big crater-like ones. The first kind--reddish and flat--aren't so bad. They tend to fade within six months (if you leave them 'alone!). Others are bumpy with rough edges or look like depressions in your skin. If you're dark-complected, you might get light patches where the zits were. You're lucky--young skin easily repairs itself. First, get the zits in check. After all, fewer outbreaks equal less scarring, explains Los Angeles dermatologist Dr. Karyn Grossman. Use an antibacterial cleanser (like Cetaphil) twice a day, and try salicylic acid acne pads (such as Stridex Pads) once a day. At night, use a pea-sized dab of benzoyl peroxide lotion on affected areas. On scars that won't go away, try an over-the-counter retinoid cream, which helps skin build collagen (look for products by Neutrogena or Roe). If those don't help, your dermatologist can give you a prescription for Retin A. If that doesn't do the trick, your dermo might recommend laser resurfacing, chemical peels or other options. Now, no more popping!

My stomach growls and is gassy. On weekends, it's not so bad. But this happens all day at school! What call I do to stop it?

Tummies growl and intestinal tracts produce gas--our bodies are required to do these things. As for the growling, it just means your tummy muscles are contracting as they send liquids and food particles to the small intestines. Growling is good--it means everything is working properly. Sorry, no suggestions for taming the noise. As for gas, passing it six to 20 times daily is normal. You might toot more when you drink carbonated beverages or change your diet. Fizzy drinks produce air--and what goes in must come out. Fibrous veggies (like broccoli, squash and spinach), dairy products and beans are good-for-you foods, but your body can't break them down fully. The undigested parts wind up in the colon, where friendly bacteria gobble them up. The bacteria then produce gas, explains Dr. Robert Herman, a gastroenterologist in Manhasset. N.Y. Perhaps some gas-inducing foods are in your typical before-school breakfast or cafeteria lunch. Figure out which foods affect you, and avoid them on school days. Worst case, you can minimize embarrassing episodes with an over-the-counter charcoal tablet such as Charco. Yes, charcoal. It's safe and absorbs some of the smelly you-know-what. Pee-ew!

I drool when I sleep. Sometimes it gets all over my face and pillow! How can I stop this? What's wrong with me?

Doctors have a fancy term for nighttime drooling: sialorrhea. And it's super common. So rest easy--nothing is wrong. We produce more saliva during the day, but we are tidy about it because we swallow a lot. At night, we forget because--duh--we're sleeping. If you lie on your side, sial-whatever-hea is more of a problem as saliva pools up in your cheek and seeps out, explains Dr. John Winkelman, associate director, Sleep Disorders Service, Brigham and Women's Hospital, Boston. Sleep on your back--when the spit collects back there, it triggers a swallowing reflex. If you keep slobbering, who cares? Drool is nothing to lose sleep over.
