I wish I had the time - or the funds - to go on a tropical vacation right now. However, I can fake the look of a Caribbean getaway overnight with this viral tanning butter. Tanning products can be really hit or miss for me: More often than not, I end up looking orange and streaky rather than glowing and golden. This goof-proof gradual tanning formula from Bali Body seems to be a winning option, though. It's become an instant best seller on Amazon thanks to its low-maintenance lotion format that results in the most realistic-looking tan.
