Hi. I don't see how the moxi can reach a cyst. Maybe with the help of dmso. I am averse to using many meds. Albendazole taken with 20+ grams of fat daily for 28 days put me in the hospital for a week for three blood transfusions (and a slew of expensive tests because I never revealed that I had taken the ALB).
I don't shoot iver into my skin, so there are hardly any concerns other than cleanliness. I draw a bead of iver onto the tip of a syringe and insert the needle into the heart of the excoriation. Enter the skin at an angle and make sure the longer side (not the opening) is facing down toward the skin. Watch a Youtube video on the mechanics of needle insertion and you'll see what I mean. There is no burn. If it burns, you went too far and probably bypassed the cyst.
I use a 29 gauge, 1/2" needle length, 1.0 mL insulin syringe. Smaller and you won't open the skin enough to get the molecules in.
