If the explosion of cosmetics geared towards skin type tells us anything, it's that a one-size fits all approach no longer flies when it comes to what you put on your face.

But how do you know what your skin type is?

To figure out if you have sensitive skin, all you need is water and an hour of free time. The next time your face is make-up free and you don't have anywhere to be for an hour, you can try this at home skin test.

Start by splashing your face with tepid water ten times (no soap!). Using a dry towel, carefully pat away the excess moisture so your skin can air dry. Wait 30 minutes before returning to your bathroom mirror. Looking at your face in the mirror, furrow your brow and smile widely. If your face feels tight and you know that you frequently break-out, you have sensitive skin.

Knowing whether or not you have sensitive skin puts you one step closer to taming that confounding complexion of yours. So for those of you with sensitive skin, you should check out Aveeno, Eucerin and Neutrogena. All three companies have great product lines geared towards folks with fickle faces.
