What is a shower scrub bar? A body scrub...but solid! Rub the bar directly into your skin or distribute onto your skin with your hands. Rinse well. You can use it anywhere on your body, but it's especially great for rough bits like elbows and feet. These luxurious little bars have got tons of cocoa butter, mango butter and rich avocado oil to moisturize while ground apricot kernels and sugar exfoliate.
