I'm torn between having it done in Thailand or Korea. Can anyone give me some advice?

Hi, my name is Muk. I wanted to ask about something I've been thinking about today. I'm interested in some non-surgical skincare treatments, but I'm unsure whether it's better to do it in Thailand or in Korea. Thailand is closer and more convenient, but I'm concerned about the accuracy of the techniques and post-treatment support.

From what I've heard, Korea seems to have more experience and a larger number of specialists, but I also need to consider the cost, airfare, and follow-up after returning home. I'm really still undecided.

Has anyone been in a similar situation? Why did you choose one over the other? Do you have any opinions or advice for me to consider? Thank you in advance.
