What's cooler than a spray-on self-tanner? How about one you can use in the shower? Rub this time-saving Ethique Eco-Friendly Gradual Tanning Bar ($32) all across your body whilst you clean and emerge from your bathroom a golden goddess. OK, it won't work quite that quickly — the orange-free bronze finish develops on your skin from four to 24 hours — but the fact that this is the world's only tanning soap is pretty rad. Radder still is the fact that it lasts up to 10 days (if you keep your skin in tip-top, hydrated shape), and it comes in biodegradable, TSA-friendly packaging so no waste is left behind.
