Love it !!! I will use this til I die, it is smoothing out my awful cystic acne scars, I used it once a week ,my cheek skin is thick so I can handle 1 treatment a week, also going for my lines above my lips & forehead, my whole face, after you first do a treatment your red, but most of that is gone next morning, except on my forehead eleven lines I go over a few times where I need it . Thanks Glov !!!! lorri
