JoyfulNoise has posted that it disrupts CC (not FC). If my end result is to get rid of these brown stains, then should I just go straight to the Zero Alk treatment? I had to fight to get them to cover that, and they are now willing to do it. They of course are pushing me to try the Jack's treatment first, A) because it's on my dime and B) in the hopes it makes the brown stains look better (they blend in more). At least that's my opinion.
