I only had a consultation, so I do not really know what the doctor is like.. so for now, 5 stars.
It is quiet and comfortable when you go there; waiting is not a problem.
The staff are mostly kind, but the issue is the consultation, which is quite forceful.
As is widely known, for an injection-based procedure the price is quite high, and the consultant sets a floor price and threatens that if you choose something else, the effect will not be very good.
Still, perhaps because they have worked there a long time, if you ask about various things they answer without hesitation..
