Sunscreen. This is the one step where the Korean shelf is genuinely better value than most places. Beauty of Joseon Relief Sun, SPF50+ PA++++, 50ml, ₩12,000–₩18,000, is the product that made the brand travel: chemical filters, essentially no white cast, matte finish. The catch is that chemical filters sting some people's eyes, and the matte finish is unkind to dry skin, which wants a moisturiser underneath. Reapply every two to three hours outdoors. The sunscreen page and the no-white-cast comparison cover the alternatives.
Cleanser. If you wear sunscreen daily you need something that removes it properly. Bioderma Sensibio H2O, 500ml, ₩26,000–₩34,000, ranked first in olyoung.shop's tally of 482 real user recommendations across 323 products, checked on 17 August 2026, with four Olive Young staff flagging it. It is French rather than Korean, and the reason people buy it in Seoul is that it costs less here than at home. It is also half a kilo of liquid, so it is a checked-bag purchase. An Anua cleansing oil does the same job in a smaller bottle.
Cream. Two sensible options depending on skin. AESTURA Atobarrier 365 Cream, 80ml, ₩28,000–₩39,000, is the most-mentioned product in that tally with 14 recommendations, and it is a plain ceramide cream rather than a trend. It is thick, and in humid weather the lotion from the same line is the better buy. For normal to combination skin, Round Lab 1025 Birch Juice Moisturizing Cream, 80ml, ₩20,000–₩26,000, is fragrance-free and frequently 1+1.
