When I was a teenager, I wouldn't be caught dead without my lip gloss, blush, eyeshadow and eyeliner at all times. Now, even though I'm older, I'll admit I still don't feel 100 percent confident leaving the house without at least some of my "face" on-plus, my obsession with beauty products doesn't encourage me to go makeup-free very often.

While I can talk your ear off about how much you should buy this trendy, awesome orange lipstick or this cool blue eyeshadow, celebs like Gwyneth Paltrow and Zoe Saldana are making a strong case for embracing natural beauty in their latest Instagram selfies. I think the famous faces above make a good point: sometimes letting your skin take a breather is not only healthy, but can also be totally liberating.

Though I'm not suggesting you lay off all your beauty products for good (because what's the fun in that?), it's nice to see some stars prove that being comfortable in your own skin is just as attractive as a pretty red carpet look.
