I only had a consultation, so I don't really know what the doctor is like.. so for now, 5 stars.
When you go, it's quiet and comfortable. There are no issues with waiting.
The staff are mostly kind, but the problem is the consultation, which is quite forceful.
As is widely known, it's a fairly expensive procedure among injectable treatments, but the consultant sets a lower price limit and warns that if you choose something else, the effect won't be very good.
Still, maybe because they've worked there a long time, if you ask various questions, they answer without hesitation..
