I used to work for a dermatologist so my brother comes to me with a lot of questions in regards to his skin and moles. He recently developed patches of brown freckles and spots, similar to melasma and thw patches of freckles on his calves. He fears it is petechiea, I don t feel it is that serious. Could it be something else that comes with age like melasma? He currently takes lisinopril for high blood pressure, is overweight for his age at 41, and has worked in the plum,bing industry for years.
