Global derma skincare brand COSRX announced from New York on July 29, 2026, that it secured five top-five category placements on Amazon U.S. during Prime Day 2026. Held from June 23 through June 26, the promotional period saw COSRX achieve major rankings across multiple product areas, reinforcing the reputation of its essentials-only approach to skincare solutions.[1][2]

Leading the results was the COSRX Low pH Good Morning Gel Cleanser, which ranked No. 1 in the Facial Cleansing Gels category on Amazon U.S. The top performance placed the product ahead of competing items throughout the four-day Prime Day event.[1][2]

In addition to its flagship cleanser, COSRX saw established brand icons and newer product launches rise to top category positions across facial serums, toners, eye masks, and facial masks. The broad performance across multiple skincare categories showcased the strength and reach of the wider COSRX product lineup.[1][2]
