OK, we all know that we need to wear sunscreen every time we go outside. But, in reality, as the days get longer, many of us find ourselves taking part in outdoor activities at the last moment, and we either don't think about applying sunscreen, or don't want to take the time to go back home to grab it.

I have two solutions for you. Both are totally portable and mess-free, and both will fit in your purse for quick application on the go. See? No more excuses!

First up is Mission Skincare's Anti-Sting SPF 30+ Facestick ($8.99). It looks like a giant chapstick, only the product inside is designed to go on your face. It's designed to be both sweat- and waterproof, is oil free and vitamin enriched and is free of preservatives, parabens and PABA. I've found it most useful when I need to reapply to the areas of my face that get burned most easily -- my nose and cheeks. It goes on a little thick and is easy to spread out. I can't guarantee, however, that it will go on effectively over makeup.

The next product, though, goes on perfectly over makeup because, essentially, it is makeup. Peter Thomas Roth offers Instant Mineral SPF 30 ($30) in a brush form -- you simply shake, remove the cap and brush on anywhere you want sun protection (face, chest, hands, anywhere). It's a translucent, matte powder that can go on over moisturizer or makeup. It'll hold up to a bit of sweating, but should be reapplied after excessive sweating or swimming.

Additionally, a super simple solution is just to keep a travel-sized bottle of your favorite sweatproof sunscreen in your purse, and try applying a moisturizer with SPF every morning before you leave the house. This might not help you cover every area of your body, but I'm sure we can all do with a little more coverage on our faces, right?
