Using deodorants and sprays are some reasons why your underarm looks darker. It is because it contains chemical which can be responsible for this embarrassing problem. If this is the reason then avoid applying deodorants and sprays directly to your skin. Waxing thoroughly removes the hair from its root instead of trimming or cutting down hair that gives dark color. You can also try the following remedies to lighten your underarm.

First, cut a fresh lemon slice then rub it on the skin of your armpits and wash it after 15 minutes. Lemon is a natural bleaching agent that will really help you to lighten your underarm. Another remedy is by using baking soda after taking your bath or shower. Using alum powders instead of deodorants avoid further darkening of the skin of the underarm. You can also make your own home remedy that can be so useful. Take a 1 tea spoon of cucumber juice and 1 tea spoon of lime juice and then add a pinch of turmeric powder to it to make a thin paste. Apply this paste on the skin of your armpits and wash it off after 20 minutes. Another remedy that can be beneficial to you is the Vitamin E oil and aloe vera gel when applied to the skin of your underarm. These remedies will really help you in those underarm problems. I hope my suggestions will help you to solve this kind of embarrassing problem.
