@playlabbeauty: It’s a K-Secret! 🤯🤣 If you’re a Seoul 1988 Retinal Serum loyalist, get that bulk deal from Costco. Straight up better price than what we buy it for as a retailer. When K-beauty brands compete for your love, that usually means dropping those prices. Great news for the beauty shopper, bad news for small retailers, but not trying to gatekeep this deal. It’s too good! Yes, this is the authentic product sold by the brand, not reformulated for the U.S. Though this brand was created as an “export brand” so it was never popular in Korea and thus “original Korean formulation” isn’t relevant here. #kbeauty #costcofinds #costcotips
