COSRX is one of the most well-known Korean skincare brands, combining cosmetics with dermatologically inspired, functional active ingredients. The name stands for "Cosmetics + Rx" ("Rx" as an abbreviation for prescription medicine) and underscores the brand's scientifically oriented, problem-solving approach.

The formulations are minimalist and deliberately avoid irritating ingredients such as parabens, artificial fragrances, or alcohol. Instead, COSRX relies on clinically proven active ingredients such as Centella Asiatica, Niacinamide, Hyaluronic Acid, Salicylic Acid (BHA), and Propolis.

COSRX combines modern dermatological research with the gentle K-Beauty philosophy, standing for highly effective, clear, and functional skincare. The brand is cruelty-free and also values more sustainable, reduced packaging solutions.
