Genius Beauty Hacks for Dark Circles, Frizzy Hair, and More

In a perfect world, you'd never wake up too late to wash your hair, and you'd be able to pack your whole bathroom seamlessly every time you go on a trip. But, alas, in the real world, alarm clocks fail and there's that whole "size restriction"-thing airlines insist upon. No worries.

Learn these derm-approved hacks now so the next time you're in a beauty pinch, you'll know exactly what to do.

Eye drops for dark under-eye circles or bags

Too much partying, savory eats, and a lack of sleep equals a one way ticket to #bagsville. A nice afternoon snooze and loads of H20 may be helpful, but if those two aren't in the cards, grab some Visine ($7, The culprit, again, is cortisol, which leads to water retention and blood vessel dilation, most obvious on our thinnest skin, the eyelids. Visine constricts those vessels, Dr. Chiu says. This lightens the circles and squeezes fluid away from the eye.

Teeth whitening strips for minor cuts and scrapes

Nick your leg while shaving? Do not fear, teeth whitening strips are here. Okay, it sounds weird, but they work in a pinch. The strips are made of peroxide, which is much better than water at cleaning out bacteria. (Using peroxide repetitively to dress a wound can be damaging to the skin, but once is just fine.)

That short amount of time is usually enough to stop bleeding and ensure cleaning.

These are an all-around fixer: whether you're traveling (and you've picked up the ever-so-sultry eau de airline), dealing with major humidity, or you don't have time to wash, it can help. Reach for a nicely scented dryer sheet, and rub it gently along your hair to tame your mane. The smell rubs off, plus its smooths frizziness, thanks to the sheet's static.
