then why not doing it at the dermatologist's clinic? (or another skin clinic refer by him/her)

Then may be you need to find another (i.e. a better) dermatologist. I don't see why going to a beauty salon is a better choice.

I have never visited 黃永昌. But as another lyk said "黃永昌is not even a dermatologist."
