At-home treatments vs. getting treatments in Korea — how did you decide?

Hi everyone, I'm Yunru. I've been debating whether or not to go to Korea for a treatment lately. There are clinics in Taiwan that offer it, but I've always heard that Korea's technology and equipment are newer and more advanced? However, I also need to consider flight tickets, accommodation, and what to do if follow-up visits are needed...

I know some sisters have flown to Seoul specifically for treatments, but I don't want to just blindly follow trends. I'd like to ask everyone, how do you weigh this decision? Are you concerned about language barriers? Or is getting it done locally actually quite good? I'm really not sure if I'm overthinking things.

If anyone has had a similar experience, I'd love to hear what you were thinking at the time and what choice you ultimately made. Thanks!
