Honestly, I think the effects only last for 2 weeks. When I look at other old laser posts, there were posts saying that it looks more saggy after 1 or 2 years, so I naturally assumed that I would have aged in the meantime. LOL When I see my face returning to the same state in just 2 weeks, I wonder if it really makes me older. LOL It seems to be in the same laser family as Inmode/Shrink/Double, but it might be better to spend a lot of money and get Tune Face (high frequency). I don't know (I haven't tried it)
