"it doesn&#039;t get any better than this. it has stopped a barely visible blister from making to the surface. it is an obvious instant &quot;kill&quot; on a well formed blister because the fluid turns it to a blood blister and the healing is done in half the time. the only complaint is that i had to use a cotton swab and it took 12-24 hrs for obvious results. i have a blister now and i have searched high and low for some in my area. how is that no major chain can have this medicine in my area?
