@OutgoingWhippBefore and after pictures mean "absolutely nothing," the experience of the Dr as a scar specialist matters more (only about 1% of the Drs). Photoshop is a thing marketing companies do all sort of tricks. Drs use lighting to hide things and "different" B&A photo techniques. While Korea clinics are cheap, the cost of travel from the USA is really not worth it as it ends up the same, unless you live nearby or are traveling there. We have had Drs who made mistakes in South Korea as they are not under the same medical standards (even though they are quite advanced technologically) as the USA/AUS/Europe. You contact them by searching and emailing, simple Google. Aftercare is also a big consideration here as you fly in, get treated, and need other treatments, - Aftercare, which many do not have the time to stay for months of treatment.

There is no such thing as glass smooth perfect skin if you have mid to severe scarring. If it's just slight surface scarring,... sure maybe. Drs often take pics under swelling and makeup to hide things. You have to take pictures 6-to a year after final treatment.
