I have been suffering from melasma for about 4 years now. It's on my forehead,and both my cheeks. I have tried everything from bleaches, cosmelan to IPL. Everything is short term. Just as recent as December, 2007, I started taking MSM, vitamin C as well as applying apple cider vinegar on my face. The results are amazing. For the first time in 4 years I can actually say my face has improved and I don't mind going out without makeup. It's only been 6 weeks and I intend on using this remedy to see if it'll get even better. I do hope my experience and information sharing will help someone out there, that has melasma. Good luck!!
