Costco offers its members the Case Full Of Seoul Best Of Korean Skincare 11-Piece Set for $149.99 with free shipping. (Non-members pay an extra $7.50.) That’s at least $137 under buying most of these items separately; some items are otherwise unavailable to purchase individually from legit retailers. Curated by Korean beauty incubator Umma, this set includes everything you need to follow a daily skincare routine. Brands in this kit include May Coop, One O Seven, Urang, and I Woke Up Like This.
