I have been facing this problem for almost 3 years now, The skin around my lips have become dark (not completely but in small patches ), I went to 4 or 5 doctors until now but I have not seen any improvement even after regular medication. I even turned to Homeopathy but still no results, I read about it on the internet and found that there are multiple reasons for these dark patches on my skin. One of the doctors in Ghaziabad gave me a cream Called Momate which was very quick to remove the patches but as soon as I stopped applying it the patches returned. I am really clueless now as to what should I do. I have long been keeping beard and mustaches to hide the marks. I really want to get rid of these spots.
