than those that have a subclinical infection under their skin.
What you do is buy
cotton balls or pads, soak them in the vinegar, and apply them to the skin. You then need to hold them on to the area, I suggest medical tape or gauze. Either way, leave it on as long as you can, it may sting and be a bit uncomfortalbe, but it's nothing I've found to be unbearable. It's not clear how much or how often your supposed to do this.
