i had narrowed it down to three things:
my microderm abrasion kit (maybe i've had it too long, and it's causing a reaction?)
my backup face powder (i use the brush provided, not my 'spensive kabuki(sp?) one)
the juice smoothie i drink every morning (it's a 2 serving bottle of juice that i drink over 3 days. On the third day, i drink it straight out of the bottle.)
Since my hives were coming every 3 days, i was relatively sure it was the acai juice/smoothie, because i was getting the hives every 3 days.
so i stopped the juice but the hives didn't stop.
turns out it's the BRUSH of the back-up face powder i've been using.
i really just need to re-order my Mary Kay powder and throw everything else away. my poor sensitive face, lol.
