this maybe considered wonder drug for whitening.... actually it is not a whitening drug, it's an anti toxin formulation that regulates kidney function to eliminate hamrful toxins..it's adverse effect would be minimizing the skin pores thus having a firmer look that may seems to whiten skin.....when taking this one should tale at least 1000 mg of vitamin c, or if u a smoker and a drinker take 2000 mg a day, the purpose is to fastly activate the drug for immediate effect..., good luck..
