First of all, aside from the friendliness, I was very unhappy with the consultation style.
I asked about the expected degree of improvement and the possibility of side effects based on my under-eye conditions, but they kept explaining only the methodology. Only after I repeatedly pressed them three times, asking one point at a time, did I finally get answers, and I think this place is very unsuitable as a first consultation clinic for someone with no background knowledge. I saw that the writing was good, but the speaking was different, which surprised me.
