What a key opinion leader appointment means

What it does mean

  • The manufacturer's own clinical team invited this physician to share his protocols on these platforms — not the other way round.
  • Early sight of protocol updates and device development, and a direct line to the engineers when something in the field does not behave as the manual says.
  • Protocols are developed and stress-tested with international peers, then brought home.
  • Exposure to skin types, ageing patterns and aesthetic ideals well outside one market's norms.

What it does not mean

  • It is not a guarantee of anyone's result. No credential is.
  • It is not a reason to choose a device over a diagnosis. Sometimes the honest answer at consultation is that a different modality — or surgery — suits a person better.
  • It is not a clinical endorsement of every claim a manufacturer makes. Where the published evidence is thin, he says so, in São Paulo and in Singapore alike.
  • Appointments are disclosed as interests wherever the platforms are discussed.
“The value of a faculty meeting is not the protocol you bring. It is the cases other physicians have that you have never seen.”
Dr Sin Yong
