re:nk Korean Skincare Debuts at Costco

re:nk, the Korean prestige skincare brand built on cellular science, is expanding in the U.S. with its debut at Costco warehouses nationwide.

The brand’s inaugural U.S. launch is the 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.

This cream comes in a luxe, crystal-inspired bottle with iridescent coloring and a textured cap. 

Cellestial Collagen Cream is a Korean anti-aging cream aimed at enhancing skin firmness and density. Cellestial Collagen Cream is crafted with over 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.

Hyeonji Nam, Head of re:nk, said:

“We prepared this Costco launch so American consumers can experience the technology and quality of Korean prestige skincare at an accessible value. 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.”

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.
