Hello doctor. I am using melaret cream and some other cream named like ultrasone HT which contains hydroquinone, tretinoin & mometasone furoate for past 5 years. . currently i am using melaret cream on to my hands as well as face and neck. i think i dint apply properly to my neck because i can see three different colors on my neck. these creams i am using only by consulting doctor. till now i dint face any side effects but some of the beautician says, not to use that cream coz it causes skin cancer or some side effects in future.. only one problem which i m facing is that i got some rashes around nose and mouth but i dont think so it is because of that cream. . i wanted to know whether that rashes because of that cream?? and this melaret cream details does not available in google.. whether menstrual problem occur if i use this cream? hairloss? blood cancer? please do help me out of this doctor. i am really very much afraid of my future, often thinking about this and not sleeping well, thinking whether to stop or continue. but once if i stop i will become dark. i can stop if i can get my old color back.. i cant stop if i become more darker than before.
