once i used this melacare skin cream in face and neck.It showed good results.Bt i dnt knw the fact that this cream cant be used in morning.I used this in morning.Bt after that my skin became darker due to sun exposure and i stopped thw use of melacare. Aftr searching net i came to know that this cream must be used at night and washed off at morning.And should use a sun cream during day time.But now everyone are asking to me that what happended to my face and it became darker.Can i use this cream for whitening ma face again.Because of dark skin I m loosing ma confidence now. what will i do?Does melacare cause any cancer?
