OH look it's COFFEE TIME 

Coffee grounds are a mechanical exfoliate, meaning they can be used to scrub away dead skin to reveal the new, healthy skin underneath, whereas chemical exfoliates remove skin cells with enzymes or acidic properties. Exfoliating with coffee grounds improves circulation, leaving you with smooth, glowing skin.  

“Caffeine found in coffee scrubs improves blood circulation, may reduce the appearance of cellulite and gives the skin a more even tone look. When a coffee body scrub is applied, the skin absorbs the antioxidant properties to prevent premature aging."
