After reading these posts I've started taking MSM. I take one 1500mg pill a day and have been taking it for about 3 weeks. It looks like my dark patch is starting to break up - there are little white spots showing up on it. I have severe melasma that covers my whole left cheek across the bottom of my chin, and over to the right cheek.
Today I've started taking 15 drops of Grapefruit extract in the morning. I'm hoping to see even more results - I will keep you posted!
