How much did they quote you for and what procedures did you enquire about? Because i have been very interested in getting laser procedures done and i speak fluent korean but i realise that korean blogs mostly do advertisements and blogpost to get some freebies rather than to write about their honest experiences. You can say im cross referencing with the foreign expats to make sure im doing the right stuff! Because for the Renew korean site, they have so much more procedures available and the prices are so affordable that im seriously considering going to them but reading your comment, im wondering if its a translation fee?
You're right, the Korean consumer web is kind of a big joke here, it's riddled with spam and fake content, whether you're looking for a doctor or a good Korean BBQ place. Locals tune out the opinion part and use reviews to look up info like location, hours and prices (Koreans mostly rely on their personal network's referral).
Renewme is an international clinic, so they'll have more of premium than a local clinic, but in my opinion, it's still cheaper than the US in some aspects. If you like comfort and being able to speak English with the staff, given priority treatment over Koreans and you're not on a tight budget, then it's a good fit.
I used to go there a lot for IV nutrient therapy and to treat an occasional breakout.
Last week I went to a very local clinic, the kind that when a foreigner walks in, the entire staff looks at you like a deer caught in headlights because they speak zero english, and are wondering how you managed to walk in.
I went there out of convenience because it's around the corner from me. I looked at their price sheet and noticed a lot of their packages are marked lower because they're for Koreans. I know enough Korean to get by, but not having a staff who speaks English, and being treated like a martian from another planet staff: giggling, hesitating etc... and having a doctor who can't really communicate with you can be annoying.
Also, if you're someone who has my skin tone (mediterranean, latin, middle eastern, persian, filipino, southeast asian, south asian, etc...) I would advise going to an international clinic: Woo Han, Leaders, Renewme, Oracle, HusHu, etc... that is used to dealing with different skin types and know how to adjust the settings on the lasers accordingly.
