If I don't want to shave peach fuzz hair on my cheeks for laser hair removal session, is it pointless to do LHR on cheeks then?

I want lip only but Doc has set price all face,so thinkin to get all face. Skin:White/slight olive tone/black hair.Side of face, visible thin black hair& on cheeks peach fuzz hair as if blonde.OK to shave upper lip, etc before laser, but never shaven cheeks before,so ofcourse prefer not to cuz worry stimulate growth * If I want all face done do have to shave for laser be effective? * If don't shave is laser harm to skin,cuz hair cause burn? * If my fuzz infact blonde,wil laser not get it anyway?
