Brazilian Bum Bum Cream is a skin-tightening body cream that is designed to smooth and visibly tighten the appearance of skin. It is a firming cream that is meant to be applied in small, circular motions over areas you want to tighten up, like your bum, thighs, arms, and anywhere else. The cream contains guarana, which is loaded with caffeine, making it the Bum Bum Creams main firming agent. The butter in the cream is full of fatty acids to lock in moisture. The cream is fast-absorbing and can be used all over the body, not just on the bum. It promises to give a smoother, softer, and better appearance for your entire body depending on where you choose to apply it. The cream is also known for its addictive scent. While many reviewers love the cream for its firming qualities, others love how hydrated it leaves them feeling.
