I've been back from Korea since end oct, and I did my laser (D-SRT) with Dr Park from CNP at Yangjae. He's supposed to be one of the most senior doc there.
Personally I feel that my scars are still very obvious and there wasn't a significant improvement, but 2 of my friends who knew I went to do it told me my skin looks a bit better (hopefully they weren't trying to make me feel better).
Would I return to CNP? Hmm, I don't think so actually. As I've done laser in SG for at least 10 times already (and I only have time for 1 session), the Dr increased the power a lot.
I can deal with the pain (highest level I've ever encountered before. Even with numbing cream and injection, I was yelling every time the machine was activated), and the recovery process (had to wear dressing on both my cheeks and temples area and go back to clinic everyday to change it, for about 4 days, and was oozing liquid out of the dressing on the first night), but I didn't like how the machine works. He was lasering my skin like how you would use a colour pencil to colour a picture - back and forth (with a pause maybe after about 5 secs of back forth lasering).
The lasers I've done in SG are very systematic, one square at a time, 1 zap 1 pause, so that no areas get over-repeated, and later doc will zap a few more times on problematic areas. At CNP, I had so much fear that the doc will over burn my skin, which he actually did for a particular area on the side of my face just below my temple, about a 10 cent coin size. That spot took the longest to heal, scabs at the other parts of my skin had already dropped off, pinkish skin can already be seen, but that 10 cent coin area was still super red and raw. Dr Park let me undergo a regenerative laser (basically red light therapy) for free (3 times i think) to help my skin heal. Until the 4th day, he wasn't in the clinic, I saw another doc for my last follow up before I left Korea, and the nurse said I couldn't do the regenerative laser cause Dr Park was not around. -_-"""
When I got back to SG, ~a week after the laser, my thickest concealer couldn't completely conceal that 10 cent spot, and it eventually turned into PIH (post inflammatory hyperpigmentation). Was really mad, cause after doing 10 lasers before, I had never had PIH before, so I know my skin is not prone to it, and it was because the doc had let the laser stayed at spot for longer than it should. There's no major deep scar at that spot either, I had another worse scar at another part of my face.
Dr Park had prescribed hydroquinone - a bleaching cream (which I had to buy from pharmacy), and thankfully it sped up the healing of that PIH spot.
Now, it's been about 2ish months, the 10 cent spot can thankfully be covered by concealer.
What made me more upset, was that I emailed them to voice my unhappiness, and they said I should have told them I had an important event soon after I'm back in SG so doc can do a milder laser (which I did tell the doctor many times), but the point was the other parts of my face was ok, it was only that bloody spot (almost literally)!
In any case, I must say my laser was not the normal strength, if anyone of you are thinking of doing, it'll be way milder first, so you prob will not encounter my kind of pain and recovery process yah.
I'll prob be looking more into specific scar spot treatment next, instead of a big general area kind of laser (since I had done that numerous times already, which I would say did help, but not effective for me already).
