I have skin laxity in the lower half of my face and neck. I am not willing to go under general anesthesia right now, so am weighing the best non-surgical options. Facetite is highly reviewed but mentions fat dissolving, as I am quite thin, I worry losing any fat would actually age me. Profound seems like another strong option. There are SO many rf treatments out there - which one would be best for my goal to get the most bang out of one session?
