If you get a blister on a burned area, it is already extremely moist. To begin, cool the
area around the burned area with cold water or an ice pack, wipe moisture on it, and
apply our wettable dressing to the blister less than 2cm in size without removing it. If
the blister is larger than 2cm, remove it and apply the dressing to it. If you are
concerned about secondary infection, you must remove the blister and apply a wettable
dressing to it.
