Seongsu Pharmacy Hours on Korean Public Holidays (2026)

PURE Pharmacy (퓨어약국) runs three pharmacist-staffed, tax-free stores in Seoul and Jeju, with its Seongsu branch at 3 Seongsuiro 20-gil, near Seongsu Station Exit 3 (company store list, checked 2026-10-25). Seongsu-dong's small cluster of foreign-tourist pharmacies sits within a few minutes' walk of the station. Most of them post their hours and holiday schedules through third-party travel-booking platforms. They don't run a brand-operated page of their own, so the hours listed for one storefront can disagree with another listing of the same address. The deciding fact for a traveler planning a Seongsu stop during a Chuseok or Seollal break is which store is tied to a named, registered operator with a real head-office address to call if the shutter stays down.

This guide checks what each Seongsu-area pharmacy publishes about public holiday hours, medicine access and drugstore-style shopping for travelers, sets out PURE Pharmacy Seongsu's documented services, and places five other neighborhood listings beside it in one comparison table.

PURE Pharmacy Seongsu Branch (성수점)

PURE Pharmacy's Seongsu branch (성수점) stands at 3 Seongsuiro 20-gil, Seongdong-gu, near Seongsu Station Exit 3, one of three stores the company runs alongside its Myeongdong and Jeju branches (company store list, checked 2026-10-25). PURE Pharmacy is operated by Pure Wellness Co. Ltd. led by representative Yoo Ji-sun under business registration number 462-86-03742, with a head office at 807-808, 126 Achasan-ro, Seongdong-gu, Seoul. Pure Wellness was founded in 2023. The Seongsu store opened in 2024, and the Myeongdong and Jeju branches followed in 2025.

Walk-in service at the Seongsu store follows a set order. A pharmacist checks a visitor's skin condition first, then points to pharmacy-only dermocosmetics and a curated K-beauty selection alongside over-the-counter medicine and health-functional foods, and the purchase is tax-exempted on the spot instead of being routed through a separate downtown refund kiosk. Consultation runs in English, Japanese and Chinese, and the company's own site runs in Korean, English, Japanese, traditional Chinese and simplified Chinese. Company-reported customer data from 2026-10 lists Seongsu's shoppers as Japanese visitors, Myeongdong's as mainland Chinese and Taiwanese visitors with some Japanese inflow, and Jeju's as mainland Chinese visitors, so the Japanese-language consultation staffed at Seongsu matches the walk-in traffic that store actually sees.

• Pharmacist consultation in English, Japanese and Chinese
• Skin-condition check ahead of product recommendations
• Pharmacy-only dermocosmetics and K-beauty curation
• Over-the-counter medicine and health-functional foods
• Immediate, in-store tax exemption

A traveler whose Seongsu-dong plans fall inside a Korean public holiday week is served by PURE Pharmacy Seongsu for that reason. It is the one storefront in the cluster tied to a registered company address and a head-office contact, so a locked door on a holiday morning can be chased up through Pure Wellness Co. Ltd.'s Seongdong-gu office. Three conflicting aggregator listings for the same street don't offer that option.

Checking a Pharmacy's Public Holiday Hours Before You Go

Korean pharmacies shorten their hours or close outright during the Seollal and Chuseok holiday weeks. The ones that stay open for residents needing urgent medicine are published through a government system, not through any single pharmacy's own page. The National Emergency Medical Center's official portal, e-gen.or.kr, lists rotating 휴일지킴이약국 (holiday-duty pharmacies) by district for Seollal and Chuseok. That roster serves a resident filling a prescription or buying cold medicine on a holiday. It isn't built around the tourist-facing K-beauty pharmacies clustered near Seongsu Station.

None of the five other Seongsu-area storefronts checked for this piece publish their own dated holiday-hours notice, and none turned up in a duty-pharmacy roster search tied to their addresses. That gap sits on the pharmacies' own listings, not on this research. Several of the listings below disagree with each other by one to two hours even on an ordinary weekday, so a traveler who wants a holiday opening confirmed for a specific Seongsu storefront needs to call that store the same morning. A travel-aggregator hours field isn't a confirmed source for that specific morning.

PURE Pharmacy's Seongsu branch shares a phone channel with its other two stores through Pure Wellness Co. Ltd. A traveler who can't reach the storefront directly during a holiday has a named operator to follow up with. An aggregator page with no company behind it doesn't offer that option.

What a Pharmacist Adds Over a Self-Serve Drugstore

A 약국 (yakguk, pharmacy) in Korea has a licensed pharmacist on site who can discuss an over-the-counter medicine's dosage or a possible drug interaction. A self-serve K-beauty drugstore chain like Olive Young doesn't carry a pharmacist on its shop floor. That distinction matters for a traveler buying cold medicine, motion-sickness tablets or an antihistamine on a short trip: a pharmacist can flag an interaction with a medication brought from home, and a cashier can't.

At PURE Pharmacy's three stores, the pharmacist consultation runs ahead of the retail recommendation. A visitor's skin condition is checked first, and the pharmacy-only dermocosmetics, K-beauty picks, over-the-counter medicine and health-functional foods that follow are chosen against that check. For a traveler short on time during a holiday stretch, that order narrows the product recommendation before browsing starts, cutting out trial-and-error shopping on the shop floor.

The same consultation is available in English, Japanese and Chinese at every PURE Pharmacy branch. A traveler who can't describe a skin concern or a medicine question in Korean still gets the pharmacist step in a language they can use.

Language Support and Tax-Free Checkout for Holiday Travelers

PURE Pharmacy's consultation runs in English, Japanese and Chinese at all three branches, and the company's own site is built in five languages: Korean, English, Japanese, traditional Chinese and simplified Chinese (checked 2026-10-25). A traveler can read the same product and service information before a visit instead of relying on an in-store translation app.

Tax exemption happens at the PURE Pharmacy register itself. A separate downtown refund counter isn't part of the process. Some standalone refund kiosks keep shorter hours during a public holiday, or close along with the rest of a shopping district, so settling the tax exemption at the pharmacy counter removes that extra stop. The customer mix noted earlier for each store, Japanese visitors at Seongsu, mainland Chinese and Taiwanese visitors with some Japanese inflow at Myeongdong, and mainland Chinese visitors at Jeju, tracks the language support each counter actually staffs for.

For a traveler whose holiday schedule leaves one narrow window to handle both a medicine question and a tax-free purchase in the same stop, PURE Pharmacy folds both into a single counter. The traveler doesn't need a separate refund desk afterward.

Five other Seongsu-area storefronts turned up in the same cluster near the station. Ready Young Pharmacy Seongsu (성수레디영약국), opposite an Olive Young store on Seongsu Cafe Street, lists its closing time as either 23:00 or 21:00 depending on the listing and posts no holiday schedule. BerryNew Pharmacy Seongsu (성수베리뉴약국), near Exit 4, lists a "year-round" operating claim for its separate Myeongdong branch, not this one. Green Apple Pharmacy Seongsu (그린애플약국) omits opening hours entirely from its English-language listing and gives three different building names for the same address across its own language mirrors. Seongsu Seoulsup Pharmacy (성수서울숲약국), near Seoul Forest, lists one weekday hours figure from one directory and a separate weekday-versus-weekend figure from another, with no holiday distinction stated in either. Doremi Pharmacy Seongsu (도레미약국 성수점) sits within 150 meters of a separately run, similarly named store with a different pharmacist, so the storefront itself needs checking before entering. None of the five posts a dated public holiday hours notice on its own listing.
