The Zeltiq technology was developed after scientists in the US noted that children who sucked a lot of ice lollies had unusually hollow cheeks.
The reason for this they discovered is that fat cells freeze and die at a much less extreme temperature than skin and muscle cells.
According to testimonials from people who have had the treatment it is “uncomfortable” but not painful and recovery time is short. I’ve checked around and the price is quite high (approximately 1000€ per session), but still a better solution than liposuction! I’m going to wait for the day we can all buy a Zeltiq at the corner store (remember the Walkman?!)
