I have a underarm perspiration problem,odor,excessive wetness and black underarms.I can't wear sleeveless.?

The best skin lightener (for face, elbow, knee, armpit and body) that my wife used is papaya kojic and licorice base soap and cream. These products made my wife’s skin light, even tone and smooth as if 10 yrs ago (we're both 44).These work wonders. Maybe it will work on you too.
