I have been fighting Melasma for 4 years now. It it what got me started with a copper detox doing almost the exact same things as you molybdenum, vit c, zinc and MSM. I did get some lightening. I have been detoxing for over a year with vast improvements to my AF. It has been well worth it. I think also the Melasma is due to a hormonal imbalance but that is also caused my AF. Copper raises your estrogen levels. The Zinc and detox will bring copper and estrogen back down. I also got migraines and they are gone now.
I have also gone through a series of medium level peels. I think I have done six. Got very little improvement. I was wondering about Meladerm. Have you tried that?
Before all this I had beautiful even colored skin.
I am 46 and my hormones levels are changing also because of age and not just AF. But then you see these 50 year old women with perfect even tans. So what is different about their bodies?
