What should be done for discoloured skin due to bleaching?

Q: I am 21 years old and two years back I applied bleach on my face. Now my upper lip portion and above the chin has turned extremely dark; it appears as if there is permanent dirt on my face. I am very tense. Kindly suggest what to do to overcome these black patches?

A:Mix melalite cream with flutivate cream in equal ratio and apply twice daily for two weeks.
