Settings on the face are really good. If the hair on face is still coarse, she should stick with 18 spot 22-24 joules. If there is specific patchiness, then she can go to 15 mm and perhaps higher Joules on YAG ( IF YOUR SKIN CAN TAKE IT ). However, I would prefer the Apogee Elite Yag on your face.
Her treatment on arms and chest is not bad but I am sure that eventually she will use lower pulse widths.
