Dark armpits

Grind a few potatoes and squeeze them through a cloth. Rub the juice on the armpits to lighten the skin.

Sunburns

Soak in a bath with some baking soda to soothe the discomfort and pain due to sunburns.

Thick eyelashes

Mix some castor oil, aloe Vera gel, and a vitamin E capsule, and apply this mixture to the eyelashes at bedtime. In the morning, they will look much thicker than before.
