leave mono alone... give your skin a rest from any product for aleast a week or two... than use something else.... going to see a dermatogist you will need a Dr who understands what you want most derma will question why you want to lighten your skin and will not give you what you want....but at the same time its a double standard since the majority of fair skin people loves to get Tans it ok to ask doctors about what makes you dark but when a dark person want to get lighter its an issue..... used Fair & white to put your skin back on track but let your skin rest so it can adjust

i had a problem similiar to yours but not with the cream i was using i went to FLorida on vacation... and the sun turn my skin... extremely dark... i think my skin became extra dark because of the cream attracting the suns rays to my skin... i used strong sun block but didnt help at all... i had wait aleast two before i could see my skin lightening up again.... was the worst to months of my life.... i got so dark no body could recognize me....
