Mix 1 part coconut oil and 2 parts table salt (fine granules -- coarse ones will scratch you), 5 drops of essential oil (pick one for your skin type, like rose if your skin is dry, tea tree if it's oily, etc.) and muddled fresh mint leaves (seriously). Scrub it on your skin dry and then rinse it off.
Viola! Silky skin plus you smell delicious.
