Hi Ainokiseki, I did co2 fraxel laser at Pitangui for 200,000krw. Helps with my acne scars and open pores however my scars aren't bad, small ones, not deep or dented. One session is good enough for me. You will be red the next day and peeling off dead skin for about a week. I did it with other surgeries so I was already bruising and swelling, can't say how it'll affect if only doing fraxel. Remember to stay out of the sun and always use sunblock when you need to be out. I did mine in Feb, when I enquired about fraxel for my hubby in July, I was told doctor doesn't do fraxel during the summer.
