Question about communication during a Seoul cosmetic consultation - is English sufficient?

Hello everyone! I'm Mai, and I'm planning to get some minor aesthetic adjustments in Seoul next month. However, I'm a bit worried about the communication barrier since my English isn't too great, and I'm sure the doctors there might not speak Vietnamese.

Do any of you have any experience with this? Is basic English enough for consultations, or do I need to prepare anything else? I've heard there are places that offer translation support, but I'm unsure about the costs. Or has anyone used online translation services or any good translation apps for this purpose?

Thank you all so much! Any experience would be a great help. 🙏
