Overwhelmed, need recommendations for everything

Hello, I am a 30F traveling to Korea for the first time for a few weeks in October. I’ll be in Seoul (Myeongdong) for the first week, then Busan, then back in Seoul (Gangnam) for a few days before flying back home. I am overwhelmed with all the Instagram, TikTok and paid reviews for clinics. Can anyone recommend where and when I should go to get these beauty treatments? Trying to beauty max as much as possible in the correct order as I am thinking some procedures would need to be done first than others. I am also afraid of overpaying or being charged differently as a foreigner/non-Korean speaking

I am interested in
-head spa / scalp treatment
-Korean jelly perm (plus hair cut and maybe color if that’s allowed?)
-massage
-body scrub
-foot massage/scrub
-lash lift / tint
-brow lamination / tint
-skin analysis and maybe a basic facial? My skin is pretty good, I just want to maybe do a scrub and exfoliate, nothing invasive
-Korean manicure

I’m also trying to bring back home as much awesome Korean beauty products as possible while still sightseeing hehe

Thanks in advance!
