Is it unusual that my MD doesn't wear gloves when doing my Botox?

I cannot speak for other plastic surgeons, however it is uncommon to not wear gloves. In my practice it is standard for me to wear gloves during all treatments and procedures. If you continue seeing this MD i advise for you to request for him to wear gloves.

it's unlikely to cause any harm to you, however it is standard procedure for me to use gloves when doing any procedure on a patient.
