Cosrx

Cosrx is a South Korean skincare brand founded in 2013 and based in Seoul, in the Gangnam district. The name comes from the fusion of “Cosmetics” and “RX” — the Anglo-Saxon abbreviation for medical prescription — indicating an approach focused on the effectiveness of active ingredients, without excessive formulations. Since 2023, the brand has entered the orbit of Amorepacific, the leading beauty conglomerate in South Korea, while maintaining its distinct identity. Cosrx is now distributed in over 140 countries and positions itself as a benchmark for functional K-beauty: formulations reduced to the essentials, free from superfluous ingredients, irritants, or aggressive fragrances, designed to meet specific skin needs. Among the brand's signature ingredients are snail mucin, centella asiatica, BHA (salicylic acid), niacinamide, and propolis, selected for their compatibility even with the most reactive skin.
