Are there any places in Cheongju that provide thorough laser hair removal, not just a quick sweep?

I'm also worried about the bluish marks ㅠㅠ

Factory-style beard removal where they just vaguely rub it on is a total waste of money ㅠㅠ I go to S,now, and the clinic director there is super thorough, zapping every nook and cranny of my chin and upper lip in a private, one-on-one room ㅋㅋㅋ The equipment's cooling is great, and they adjust the intensity meticulously, so it barely hurts. After about 3-4 sessions, the faint bluish marks completely disappeared, and I don't have to shave in the morning anymore, which is incredibly convenient!
