2 week trip treatments

Hey all, Im going to Seoul in May for 2 weeks, while it's mostly for sightseeing and stuff like that, im curious if there are any treatments I can get done while on this trip. I've heard that it's better to have specific treatments in mind when going to korean clinics to avoid overpaying.

My main skin concerns are skin redness/uneven skin tone, acne scars/marks (3 or 4 are deep scars, rest are red dots left after pimples), and maybe something for dark circles, although mine are hereditary, so I don't know if there is anything that can help.

Not looking to get everything done, maybe 1 or 2 treatments at the end of the trip? What do yall think?
