Generally people are attracted to painting body parts that are troubling them. I think of it as approaching from both the inside and outside. SSKI is useful for sebaceous cysts and toenail fungus. Lugol's is useful for skin, breasts, abdomen, and much else. Paint your neck, your inner arm, your chest, abdomen, feet, whatever. You'll know if it feels right. I don't do it right now, but I loved it when I did.
