I'm curious about the InMode effect.

I remember being shocked a while back when Jang Sung-kyu appeared on a variety show and suddenly looked incredibly handsome after getting an InMode treatment. Lately, I've been concerned because I feel my skin elasticity decreasing. If this is due to aging, how long does the effect of the InMode treatment last? I understand that the principle involves applying heat to the skin to attach the device, so I'm also curious about potential side effects in this case. Prices for InMode treatments vary significantly from clinic to clinic; would it be okay to get the treatment at the promotional price (the cheapest option)? I'd love to hear firsthand reviews from those who have actually received the treatment. Also, how often should I get InMode treatments? The before and after results are so dramatic that it really tempts me to try it.
