The Story Behind COSRX
COSRX was founded in 2013 with a simple philosophy: deliver maximum results with minimum irritation. The brand name combines 'Cosmetics' and 'RX' (prescription), reflecting their commitment to functional, solution-oriented skincare. Born from years of compiling customer feedback and skin complaints, COSRX formulates products that address real skin concerns — especially acne, sensitivity, and dehydration — without unnecessary fillers. Their snail mucin products became a global phenomenon, turning an unconventional ingredient into one of the most sought-after hydrators in K-beauty. With a loyal cult following on Reddit and TikTok, COSRX remains one of the most trusted names for anyone building their first Korean skincare routine.
