According to Everything About Waxing, waxing can be painful. To lessen the pain, anti-inflammatory medications such as ibuprofen may be taken 30 minutes before undergoing this procedure. Numbing topical solutions may also be applied to the skin, but such medicines may trigger severe allergic reactions.
Beauty is not the only reason people remove hair from their underarms; waxing also helps address body odor problems. However, the delicate skin in the underarm area can make waxing more painful than some other areas of the body. Pain may be lessened if the procedure is done properly. Standard recommendations are to wax when hair is about .25 inches in length and to exfoliate the underarms before waxing.
