Where is a good place for laser hair removal in Ansan?

Since the weather is getting warmer and I'm wearing short sleeves, I'm thinking of getting laser hair removal on my underarms.

Are there any dermatology clinics in the Ansan area that are good at thorough hair removal?

I heard that if you go to a "factory-style" clinic, the hair grows back quickly, so I want to go to a place where the director is meticulous and ensures no areas are missed.

Also, I'm a bit worried about the pain. How painful is underarm hair removal? I'm slightly concerned it might hurt a lot, haha.

If anyone knows of a dermatology clinic in Ansan that provides thorough care during the procedure, please recommend one!!
