The doctor
MD · Diplomate, American Board of Aesthetic Medicine · 14 years
Narisa trained in Bangkok and completed her clinical fellowship in London before returning to open Siam in 2015. She sees a small number of patients each day because she prefers the version of this work where nothing is hurried.
She teaches at the Thai Society of Aesthetic Medicine and will not take on a patient she thinks doesn't need treatment.
“The first consultation was an hour long and she talked me out of one thing I came in asking for. That's when I knew I was in the right place.”

Consultation
Every new patient starts with a 60-minute consultation. We look at your skin, take a history, and map out a plan — no pressure to book anything that day. Consultation fee credited if you later treat with us.
