[etc] Cleft lip and philtrum scar laser treatment

I visited a dermatology clinic in Ulsan to lighten the serious philtrum scars that were only performed on my nose and lips during cleft lip surgery. I went to a dermatologist who said they would use laser treatment on scars, and received it for about 5 sessions for 300,000 won. When I received the consultation, I was told that laser treatment would not work well because these scars were deep, but my personality was strong enough to give it a try, so I proceeded. Starting from the day of the consultation, I think I received it once every 3-4 weeks, and after the treatment, my philtrum became red for about 3 days. I applied regenerating cream every evening, but in the end, it didn't work as the teacher said, so I didn't use it anymore. Currently considering philtrum surgery
