First of all, as someone who lives in the same officetel, I used to go to Muse Gangnam and then went often after Cheonhoderm opened... ha.ㅡ. The person doing consultations, the front desk staff, the skin/aesthetic care staff, and so on really seem way too inexperienced.
Especially one of the consultants was seriously rude, had no professionalism, and it was obvious she didn't want to work, so I haven't gone there since. Sometimes I see the skin care staff smoking on the bench outside. I guess they wash their hands and then take care of my skin, right? The female doctor is kind..
