Where's the best place to go in Seoul for beauty treatments? 🇰🇷✨

Hello everyone! My name is Aon, and I'm planning to go to Korea this year for a full beauty makeover. I'm a bit confused about the areas and accommodation though 😅.

I've seen many people talk about Gangnam and Apgujeong as the beauty mecca of Korea. What are your thoughts on these areas? Is there anything else to do there besides beauty shops? And importantly – is staying nearby convenient for beauty treatments?

Since I've never been to Korea before, I'm not sure how much I need to prepare. Could anyone who has been there before please give me some advice? For example, which areas did you like? Which week is best to visit? Are there any tips I should know? Thank you so much! 💕
