Just cut a lemon into two halves and rub the two wedges on the underarms for a few minutes. Leave the juice on your skin for half and hour. Repeat this twice a week and you will be surprised at the result.
Potatoes also contain a natural bleaching agent. Just rub a thin slice of potato on around armpits. You can also apply the juice of one potato with a cotton pad. Leave the juice to dry and then wash it off.
