Exercise does a complexion good, but sweat can cause breakouts. The solution: Alba Botanica ACNEdote Clean 'n Treat Towelettes ($6). They're easy to throw into any gym bag, so you don't have to worry if there isn't a sink on hand. And even though the cloths contain skin-clearing salicylic acid and witch hazel, the drying effects are practically nonexistent. Plus, if you have glasses (like me), it's a great way to clean off any bacteria around the frames, further barricading against breakouts. Now you can work out without the worry.
