How to find a trustworthy clinic in South Korea? Tips for foreigners.

Hi, this is Reina. I've recently become interested in cosmetic treatments in Korea, and I'm curious how foreigners find trustworthy clinics, so I'd like to ask for your advice.

I'm particularly concerned about language support and the quality of consultations. Does anyone have any recommendations for finding a good clinic, or any points I should check beforehand? For example, do they have interpreters, and can I consult with them via email in English or Japanese beforehand?

I would be really grateful for any experiences from people who have actually visited, or any advice on things to check. This will be my first treatment in Korea, so I want to choose carefully and without rushing. Thank you in advance!
