For all melasma sufferers follow twitter page 'be melasmafree' and facebook page 'life without melasma'. Both are providing advice on how to effectively treat melasma. They will answer any questions you might have and provide advice on the best cure. You can also download a free melasma cure guide.
I'm pushing this because I had melasma and they finally helped me cure it. It still hasn't come back and I know there are a lot of treatments out there that don't actually do anything.
