I am telling you the Zanfal will get rid of the stuff quick. I get it several times a year and keep it on hand. Zanfal removes the oils that have bonded with your skin, allowing it to heal and stop the irritation. Cortizone, calimine etc, just help with the itch, but do nothing to heal the blisters. Now if we could just find something just as effective for CHIGGERS!!!!![:@]
