It's time to stop putting off trying the iconic Bum Bum cream. Don't be fooled by the silly name, because the Sol de Janeiro Brazilian Bum Bum Cream ($45) is serious business. It smells delicious (you'll slather it on from head to toe), absorbs quickly into the skin, and is ultra-hydrating. The best part? It contains a high amount of caffeine to firm your bum bum.
