Is it safe to use melonin inhibitor to do fairer skin . does melonin inhibitor cause any disease in man like vitligo or other skin disease.

It is generally safe: .... it all depends on the chemical product. Mercurous chloride and hydroquinone have been shown to potentially be harmful. Hydroquinone is commonly used, but obtaining it by prescription under the supervision of a doctor is safest. Apparently common skin lightening products available in Africa have been shown to promote skin cancer. Use under direction of a doctor. Good wishes:)
