The term "non-surgical" is used to describe any technique that does not involve cutting (i.e., incisions). It does not refer to what degree of anesthesia is used.
So a procedure such as nostril reduction that is performed under local anesthesia (injections of numbing medicine) is still "surgical." Typical non-surgical treatments include things like Botox injections, injections of wrinkle fillers, chemical peels, etc.
