I am 57 years old. From last three years dark patches started to appear on my left side of the face. Now after three years the dark patches have spread more on the left side of the cheek, on the forehead, a smaller patch on the right side of the cheek, chin, neck and now I find a small patch on the tip of my nose and even on the inner side of my arms. I have already applied 8 weeks triloma cream on my face and neck. It has helped about 40% has gone. I am not supposed to put the cream for more than 8 weeks. Now that I have stopped using the cream I am afraid the patches will get darker again. I am also wondering why the patches are appearing on my arms. I need help. Can homeopathy help? Please advise. What is this condition? I am taking calcium tablets and alfa d on a daily basis I am also taking blood pressure medicine. Could some medication cause this problem? I need to know if there is a permanent treatment for my condition.
