Flagship Cellestial Collagen Cream arrives on Costco beauty tables October 7 at a reasonable price

SEOUL, South Korea, Sept. 23, 2026 /PRNewswire/ — re:nk, the Korean prestige skincare brand built on cellular science, is officially expanding its U.S. presence with an in-store debut across Costco warehouses nationwide. While sold at department-store prices in South Korea, re:nk brings its signature “Smart Luxury” philosophy to American consumers—delivering prestige-quality formulas at exceptional warehouse value.

Leading the debut is Cellestial Collagen Cream, re:nk’s prestige-tier moisturizer, offered at an affordable price. This rollout marks a significant milestone in the brand’s U.S. growth, transitioning re:nk from an online-only presence to physical retail shelves across the country.

re:nk launched in 2010 as a Cell Derma brand built on cellular science. Its research aims at one thing: rebuilding the structure skin loses with age. By focusing on formulas that support and visibly restore the skin’s natural structure and elasticity, re:nk has earned a solid position in South Korea’s prestige skincare market.

Cellestial Collagen Cream is a Korean anti-aging cream aimed at enhancing skin firmness and density. Its proprietary complex, re:nk Cellestial™, combines Vegan Collagen and ten Peptides with vitality-boosting Astaxanthin and radiance-enhancing Camellia Leaf Oil. The formula also carries Decorinyl®, an anti-aging peptide that mimics the binding site of Decorin, a skin protein that declines with age.

What sets the cream apart is its formulation base. While most moisturizers rely primarily on purified water, Cellestial Collagen Cream is crafted with more than 50% collagen water. The brand calls the result a Liquid Collagen Plumping experience—a sense of moisture filling the skin from within—and a 7-Day High-Density Plumping effect that supports visible improvement in skin density and volume within a week.

Alongside the in-store debut, re:nk is introducing its All Density Care, a holistic approach to treating healthy skin as a matter of density. The cream works on fine lines, elasticity, and barrier strength together. In a human clinical study, the brand reported visible improvement across four key skin dimensions (surface, deep, luminous, and textural), along with improvement in the skin aging index.

This warehouse launch sets the stage for a broader U.S. retail expansion. The brand’s iconic Cell to Cell® Cream is slated to arrive at Costco warehouses in late 2026, followed by the Cell to Cell® Essence in early 2027, both at Costco warehouses. The line has already demonstrated strong consumer demand online: following its launch on Costco.com last December, both the Cell to Cell® Cream and Cell to Cell® Essence achieved early sellouts, reflecting enthusiastic customer response and growing interest in Korean prestige skincare.

“We prepared this Costco launch so American consumers can experience the technology and quality of Korean prestige skincare at an accessible value,” said Hyeonji Nam, Head of re:nk. “As we expand our footprint in the U.S., we will keep building on our cellular science expertise to grow the competitiveness of K-beauty in global markets.”
