With Summer just around the corner, some of you are starting to make travel plans. The only less-than-exciting thing about planning a vacation is figuring out how to whittle your beauty routine down to a packable size. Reader lsd143 is going backpacking in Europe (lucky!) and is struggling with what to bring, what to leave behind, and how to make it all fit in her limited space.

So let's help her out by letting her know all your must-have beauty products for travel. If you're not checking your luggage and have to fit it all into that dreaded quart-sized baggie, how do you get it all in? I'm a big fan of this pint-sized Peter Thomas Roth Oil-Free Sunscreen Mist SPF 15 To Go ($8). I often keep it in my purse for SPF touchups even when not traveling.

Share your choices by bookmarking items from around the web and tagging them with the phrase travel essentials. I'll feature your favorites here next Tuesday.
