The treated skin will look red, and possibly raised. It will feel cold for a few minutes. You may also experience slight stinging and itching for up to 10 minutes, this is a normal response. The treated area may look darker as the necrosed tissue dies and falls away … healing can take a few weeks, depending on the size and depth of the lesion. Occasionally a blister may form, it is rare but regarded as a normal occurrence. It should not be picked or popped.
