I am 32 years old. A doctor told me he could "buff out" my marionette lines using a laser. Can lasers be used in just 1 area? It seems like I'm younger than the typical patient who has laser resurfacing. As a second part to my question, would it be beneficial to have my full face treated as a means of promoting new skin growth (as a preventative measure- like a peel) if I have the time, money, and inclination to do so?
