Teach you some effective methods.
If even after shaving, the skin on the groin area looks dark and it causes you discomfort (though nothing really awkward), I will teach you some effective methods.
Recommended:
Baking soda
All you need to do is mix baking soda with water to make a thick paste. Now, apply this paste to scrub your underarms twice a week and scrub the underarms. After you are done scrubbing, just wash the mixture off and pat dry the area.
Coconut oil
Just massage your underarms with coconut oil daily and leave it on for fifteen minutes. Post that wash it off with normal water.
Lemon
Lemon is considered to be a natural bleaching agent. Just rub half a lemon on the dark area every day for two-three minutes before taking a bath and you will see a remarkable difference.
