I think the zapper is working. You just don't know it yet.
You can put the zapper directly on your face.
ALso, try Dr. Clark's parasite cleanse 30 day program.
I would also tell you to try a Bentonite clay and apple cider vinegar mask. It would help pull those toxins out of your face. (Purchased at your local health food store)
One thing to remember----when you are dealing with toxins leaving your body, your face may first have to get worse to get better. (What a disgusting thought---BUT TRUE!)
