wart on finger, may have damaged it with bazuka gel
I have this wart on my finger so I got some bazuka gel which has acylic acid (? I think that's it, sorry if I'm wrong) and is used for warts and verucas. Anyhow, I've used it a few days but after peeling some of the layer off and I don't know if I pulled too much. Now the wart is half black! Is that normal? Has anyone used this product before?
