It's a fantastic sign that you're dislodging old toxins, but also a sign that says you must do more cleansing of the paths of elimination so that the body doesn't have to use the skin to exit toxins. :) If it's using skin, that means it's also stressing the liver, colon and kidneys, and that's not good.
So be sure to do some enemas, a coffee enema would be great, or colonics, and a detox bath. The breakout should subside within 2 days that way. :)
