Lemon is one of the more popular choices for naturally removing dark underarms, as it has a bleaching effect. However, it should also be noted that it may cause a condition called phytophotodermatitis wherein fruit juices cause a painful burn on the skin.

Lemon has natural cleaning properties and it can also function as an anti-septic and anti-bacterial. It can exfoliate dead skin cells and lighten the skin. You can rub a wedge of lemon unto your underarms and leave it there for a short time before rinsing off. A more gentle approach is to combine the lemon juice with honey, yogurt, or turmeric to make a paste. You can leave this paste on the skin for approximately 10 minutes then rinse with water.

Potatoes also have natural bleaching properties due to the mild acidic elements they contain, and the same can be said of cucumbers. You can use a slice of potato or cucumber and gently rub it under the arms. Another option is to grate the potato then let the juices dry on the armpits for about 15 minutes before rinsing them off. You can also use the juice from a cucumber and then make a mixture with lemon juice and turmeric powder. This may be left on the armpits for about half an hour before rinsing off.

Often dark armpits are the result of dead skin cells. Baking soda is a perfect agent to exfoliate and scrub the area to thoroughly clean underarms. In order to use baking soda simply apply a couple drops of water to two tablespoons in order to make a paste. Rub it into the armpits in circular motions and you will be able to rid the dead skin cells. Leave on for a few minutes then rinse. To exfoliate the skin you may also choose to use brown sugar with some water or crushed peanuts or walnuts with water. The procedure is still the same as with the baking soda.
