Get softer, smoother and whiter underarms with a natural scrub. Also, the scrub will help you get rid of any body odor and keep your armpit fresh and clean through out the day. Mix baking soda with coconut oil and scrub under your arms, baking soda gently exfoliates the skin removing any dark or rough patches making it softer and smoother.
Put a tiny bit of toothpaste into a small cup, mix in one teaspoon baking soda plus one teaspoon of hydrogen peroxide, and half a teaspoon water. Thoroughly mix then brush your teeth for two minutes. Remember to do it once a week until you have reached the results you want. Once your teeth are good and white, limit yourself to using the whitening treatment once every month or two.
