>- history of skin cancer ranging from basal to squamous and my skin is very very spotted/pitted from ongoing 'ice' treatments would sooo appreciate thoughts on this topic
My suggestion is to buy a good zapper. I have applied mine directly to the lesions, It stings sort of like the freezing, takes a little bit longer, but they are gone in a couple of days.
It can even get the ones that are so small that they can not see them.
Do not zap to close to the eyes though.
