Combine the coffee grounds with the coconut palm sugar. Heat the coconut oil, allow it to cool, then add it in. Add 1 teaspoon of ground cinnamon. Scoop the scrub into a glass jar. Use the scrub in the shower or bathtub. Store the scrub in the fridge and use it within 2 weeks.
Pour 1/2 cup (56 g) of coffee grounds into a bowl, then add 1/2 cup (115 g) of coconut palm sugar. Stir them together with a spoon or fork.  The coffee grounds can be used, but they must be dry. If you can't find coconut palm sugar, you can use other types of sugar, such as organic cane sugar or brown sugar. The sugar is there for exfoliation. The larger, coarser the grains are, the more exfoliating the scrub will be. If you want a gentle scrub, stick with brown sugar. Melt 1/4 cup (52 g) of coconut oil in the microwave or in a double-boiler over the stove. Wait for it to cool to room temperature, then stir it into the coffee mixture. Don't add it in while it is still hot, or it will dissolve the coffee mixture.  Coconut oil can melt quickly, so this should only take 10 to 15 seconds in the microwave or 1 to 2 minutes on the stove. Coconut oil can clog drains. If this of a concern to you, choose fractionated coconut oil; it is already in liquid form. If you can't get coconut oil, you can use another oil, such as olive oil. You don't have to heat it first. Not only will this help make your scrub smell great, but it will also help improve blood circulation and reduce wrinkles. Cinnamon also has antibacterial properties, making it great for acne. For a more fragrant scrub, add 1/2 tablespoon (7.5 mL) of vanilla extract in addition to the cinnamon. Note that this won't have any benefits for your skin. The best type of jar to use is a short jar with a wide opening because it will be easier to reach into than a tall jar with a narrow opening. Don't use a plastic jar, however, as the plastic can leach chemicals into the scrub. Keep the jar tightly sealed when you aren't using the scrub. It can have a screw-on lid or a latch-hook lid. Use your fingers to scoop out about 1 tablespoon (7.5 g) of the scrub. Massage the scrub over your arms and legs using smooth, circular motions for about 60 seconds. Rinse the scrub off afterwards. This scrub contains coarse ingredients, so use it no more than once or twice per week. You may be able to keep the scrub around longer than 2 weeks, but watch out for signs of mold. If the scrub starts to look strange or smell rancid, discard it.
