Have you had colonics before, or was this your first or one of an initial series?
Did you schedule the colonic(s) because you you were concerned that you might be sufferng from a toxic bowel?
I imagine it's possible that during an initial series of colonics when old impacted waste matter is dislodged and recirculated within the colon, that one effect of the healing crisis might be an Acne outbreak, but this is very uncommon.
