After sanding my Verrucas down most nights before treating them with Bazuka gel I have started to wonder if the sanding has made them spread, as I have several new ones appeared! I’m confused, my GP says, “keep sanding them down”, and the treatment says sand them down once a week. When I tried once a week I found I had a thick layer of Bazuka gel that dried up, wouldn’t come off unless I sanded it down. The thick layer of gel appeared to stop the salicylic acid getting to the Verrucas. I do all the usual soak first ect,, has anyone got any advice?
