They were the scaly ones, one came back so I've just had it zapped again, many months later. The others haven't come back. No red mark but it can take a while to 'die' and fall off. It wouldn't work on age spots on hands I don't think. I saw the doc and he sent me to the lesion nurse at the surgery, doesn't hurt just looks a bit angry for a while but the end result is worth it.
