Be careful with Fraxel my skin sagged after

Did three treatments...first two worked ok.
i spaced them out by six months or more.
the third one - ruined my face.
it sagged three weeks following the treatment. like it was noticeable - droop and soon after my jowls/ chin drooped.
i kept thinking am i imagining this but no..it ruined my face.
if you do it make sure you dont goo too hot or deep or whatever.
