Melacare contains Mometasone and also hydroquinone... this cream is not meant to be used for more than a month. stop using it immediately . There are multiple causes for facial hyperpigmentation. Sun tan, overweight, pigmentation disorders like acanthosis nigricans or melasma, lichen planus pigmentosus, rhiel's melasnosis, nutritional deficiency etc are some conditions. The patches of pigmentation need to be examined and assessed to know the cause. Treating it without knowing the underlying cause will offer incomplete and temporary relief; also it will keep rebounding. Get an online consult privately with pictures of the skin problem as well as previous consultation when the treatment was prescribed or meet a dermatologist directly for a proper evaluation of the condition. Hope this was helpful.
