Round Lab, a clean-beauty brand under Seorin Company, sold out two new products on the first day of Amazon Prime Day 2026 in the U.S.: Birch Juice Moisturizing Sun Serum and PRO Azelaic 12 Soothing Serum. Launched in May targeting the U.S. market, both items went out of stock within a month, demonstrating strong local demand. The PRO Azelaic 12 Soothing Serum is Round Lab’s first PRO line product aimed at expanding into functional skincare, and its sell-out highlights the brand’s growth potential in that segment. Other signature products also performed well: Birch sunscreen accounted for 35% of sales, 1025 Dokdo Cleanser 14%, and Dokdo Toner 10%. Overall, Round Lab achieved a 48.43% year-on-year sales increase, recording its highest single-day sales on Amazon US. The company plans to continue expanding its core U.S. product portfolio.
