Accumulation of dead skin cells is the main reason for dark discoloration under the arms. Baking soda exfoliates the skin to remove the dead skin cells and unclogs the pores. Make a homemade underarm exfoliating scrub using baking soda with milk to whiten your dark underarms. Milk is a great skin moisturizer and it helps in providing soft and brighter skin. You can also use baking soda to prevent body odor which is also one of the reasons for dark underarms.
- Mix baking soda and milk to form a thick paste.
- Gently scrub your armpits with this mixture for a minute, then wash off with water and pat dry.
- Alternatively, you can use rosewater to mist under the arms to keep the skin soft and smooth.
To neutralize body odor, mix equal parts of baking soda and cornstarch and dust it on underarms to neutralize body odor and give it a lightened appearance.
