Botox in Guangzhou

Hi Guys, tomorrow I leave to Guangzhou for 3 months for modeling and I was interested in receiving medical botox in my underarms for hyperhydrosis! My doctor recommend doing it in china vs the states as it’s astronomically cheaper and they use some western brands of botox. I tried looking online for recommendations but was hard to come across. Has anyone been to Guangzhou Institute of Dermatology? Or is there any other recommendations? Thank you!
