When you don't treat dry, dead skin, it can lead to some annoying problems. I'm talking clogged pores, breakouts, dull skin, and a flaky or rough texture. Doesn't sound great, right?

The thing is, this can be easily avoidable and fixed.

Enter exfoliation. It can refresh dull skin, leaving your face looking smooth and glowy. It's especially important as you get older because it will help stimulate new cell growth. The good news and bad news about all of this is that there are so many different types of exfoliators out there. So you've got variety, but deciding on one might take some time.

There are mechanical exfoliants, like scrubs, that will slough off dead skin when you gently massage them into your skin. And then there are chemical exfoliants, which usually contain acids like alpha hydroxy (glycolic and lactic), beta hydroxy (salicylic), and polyhydroxy.
