Beauty and wellness essentials
Verify a treating doctor and get pricing in writing before any medical aesthetic procedure, understand the difference between a cosmetic salon service and a genuine medical clinic treatment, and treat premium K-beauty districts like Apgujeong and Cheongdam as worth researching in advance given how much service quality can vary.
Food and market fundamentals
Traditional markets commonly involve a buy-then-cook or buy-then-eat-upstairs system with a separate preparation fee, price negotiation is normal at flea and vintage markets but not at fixed-price retail, and carrying some cash remains wise even in an increasingly cashless-friendly country.
Transit and daily living basics
Download KakaoMap or Naver Map before relying on walking or transit directions, understand that tipping is not standard practice in Korea, know that trash separation between food waste, recyclables, and general trash is genuinely mandatory, and identify foreign-card-friendly ATMs before you need cash urgently.
Safety and practical preparation
Save 119 for emergencies and 1330 for tourist assistance, know your nearest 24-hour pharmacy or English-speaking clinic option, understand Seoul's centralized transit lost-and-found system in case you leave something behind, and keep your accommodation's digital lock code and building intercom instructions handy throughout your stay.
