I visited about 6 times over roughly one year for Rejuran Healer. (Not exact, but around that.)
It is a place where the procedure starts right away without a consultation with the doctor, and because you wash your face yourself, it is a little cheaper than other places. If you ask, you can verify the genuine product before and after the procedure, so I went there several times.
First of all, it is a busy place, and in Myeongdong there are many foreign visitors, but hardly any of the staff are especially kind. They are not rude, so I did not worry too much, but compared with other hospitals, it could feel unfriendly. Sometimes there are a few kind staff members.
The main reason I eventually switched to another hospital was not the staff, but because the female doctor changed. The previous female doctor had excellent skill and especially caused very little bruising, but the new female doctor caused too much bruising. Since injectors are machines anyway, people say there is not much difference in skill, but when doing manual injections the swelling marks were not consistent and there was too much bruising, so I could not keep going there and moved.
The last time I went was around spring 2020, so please keep that in mind.
