COSNORI Strengthens Global Presence with US Costco Launch of ‘Long Active Eyelash Serum’

South Korean beauty brand COSNORI, under Grace Club Co., Ltd., is ramping up its global expansion with the launch of its flagship Long Active Eyelash Serum at U.S. retail giant Costco.   Long Active Eyelash Serum is set to roll out across more than 400 Costco locations nationwide, marking the first time a Korean lash serum will be available at Costco US — a milestone that has drawn attention within the beauty industry.   Recognized as a standout product in the K-beauty space, Long Active Eyelash Serum has sold over 4.5 million units globally. Its strong performance on Amazon US has helped build consumer trust and further solidify COSNORI’s presence in the American beauty market.   COSNORI’s Long Active Eyelash Serum features patented peptide ingredients that enhance lash elasticity and hyaluronic acid to maintain moisture. With a water-based formula that matches the pH of natural tears, the serum delivers gentle, irritation-free care. Its specially designed C-curl brush with a ball-tip applicator ensures thorough nourishment from root to tip.    The product has successfully completed clinical tests for eyelash improvement and skin safety, underscoring both its effectiveness and gentle formulation. Thanks to these proven benefits, the serum is rapidly gaining popularity among American consumers who frequently get eyelash lift and extensions, becoming a trusted option for daily lash care.   A COSNORI representative stated, “Building on our success on Amazon, we expect our entry into Costco to significantly expand sales in the U.S. market. As a leading K-beauty brand, we will continue to actively target local consumers with differentiated efficacy and premium quality.” Currently, the Long Active Eyelash Serum is also available in offline stores in Mexico and on Costco’s U.S. online platform.    정현식 기자presence eyelash active eyelash long active serum features
