Our underarms take a lot of beating—between the shaving, the deodorant, and the tanning, we’re bound to get some uncomfortable bumps and in some cases, the skin may even get darker than the surrounding area. I’ve used this Underarm Remedy throughout the years to give my skin in that area a little spa day, and it does absolute wonders every time. Ingredients 1 tbsp coconut oil 1 tsp baking soda Mix together the coconut oil and baking soda, then very gently scrub the underarm area with the mixture. The baking soda will help exfoliate the skin around that area and leave it smooth and soft. Leave the mixture on for another 5 minutes, then rinse off.
