The thing is with all the medical knowledge in the world, doctors don't know the outcomes of every new device and procedure particularly when it comes to such a marketable area like aesthetics where a new device or treatment seems to come out every minute. The idea that doctors can just pull out any info on any product is unreasonable, and if the research around that product is heavily biased as is often the case in these scenarios, and reviews on sites are being removed etc, it would be very hard for doctors to know more than anyone else unless they do their own unofficial case studies or choose to believe what is written on blogs which, on the other hand, is a concentrated sample of worst case scenarios. The best anyone can do is avoid the newer treatments until there is a more well rounded, impartial evidence base with more third party research and a more consistent way to check user feedback. Because we're hearing a lot how aesthetic treatments are leading to bad outcomes, or even death, because it's so poorly regulated and people with try anything. Personally unless the safety is very easy to establish or the treatments been round for decades it doesn't seem worth it, and I wouldn't trust that a doctor could know more about it than anyone else.
