Allergan Plc (AGN)

RF-frequency devices for aesthetic applications go back at least 15 years to a company called Thermage (#msg-3876193). The THRM device never sold well and ended up being a swanky coat hanger at many doctor’s offices (#msg-11593419, #msg-29182011). THRM, which became SLTM, was eventually bought by Valeant Pharmaceuticals (the ultimate roll-up company) in 2013.

THRM’s device used RF-frequency waves to heat cells. I’m unclear how RF can used to cool cells, as AGN’s CoolTone supposedly does.
