I am a 55 y/o male in Sydney. No deep wrinkles. Beginnings of jowls and neck laxity, lower eye bags. Three devices appear to be on the market - Infini, Fractora and Profound. It is difficult to work through the literature on the internet for facts. I question if reviews are representative of all those who have had the treatments. What is the history of the development of these device - has one superseded/improved upon the other? Are results of treatments the same? Qualifications needed?
