The pain was a little tingling... I don't think it was severe, but the only thing that was uncomfortable was that my eyes were really bright... Other than that, there wasn't much discomfort, and I didn't even get anesthesia! The scab lasted for a week and fell off naturally. The freckles on the bridge of my nose were very dark since I've had them since I was in elementary school, but they have definitely become lighter and it will take a few more sessions for them to disappear completely. I think it usually costs around 150,000 won per session, but the event I did it as a one-time trial, so it was cheap . It feels like the freckles on the cheekbones are the same.. It seems to only work on very dark freckles . If the original freckles were chocolate-colored, they remain light brown after one treatment..!!!! If it's cheap, I'm willing to try it again later! But I'm more concerned about my skin tone than freckles, so I'll look into laser toning..!! Oh, by the way, I don't think I'll go to this hospital. The wait is so long, and they kept recommending laser treatments that I wasn't interested in.
