Which area in Seoul do foreigners prefer for beauty treatments? 🫖

Hi everyone! I'm Kim, and I'm planning a few weeks in Seoul to try some treatments. I've heard Gangnam and Apgujeong are hot spots for aesthetic treatments, but I also found it a bit overwhelming when I searched online 😅 Has anyone been there before? Which areas do you find offer a wide range of options and are safe for foreigners?

I'm also worried about accommodation. Should I stay near these areas, or are there other places that are closer but still easy to get around? I want to avoid anything too expensive 😅 Where do you usually stay when you go for beauty treatments in Seoul? Apartments or budget hotels?

Oh, and one more question - which season do you think is best to go? I only know from friends that summer is busy and winter is cold. I want to choose a time when the weather is good and it's not too crowded. Thanks a lot! ✨
