Viral K-Beauty brand, COSRX has announced the launch of The 6 Peptide Skin Booster Serum Set at Costco, which includes two full size serums (150mL) and two mini serums (30mL) designed for all skin types.
This limited-edition set was created to provide Costco members with an incredible cost-saving opportunity to experience one of COSRX’s best-selling products. Combining both value and effectiveness, The 6 Peptide Skin Booster Serum Set is available for just $37.99 – a fraction of its $60 retail value if purchased individually.
Packed with an impressive 6 peptides, the derm-favorite The 6 Peptide Skin Booster Serum addresses a variety of skin concerns, including minimizing the appearance of pores, controlling excess sebum, improving firmness, smoothing fine lines, enhancing skin texture, and soothing irritation—making it the ultimate solution for those seeking smooth, mirror-like skin. Its lightweight, water-based formula effortlessly layers into any skincare routine. Users can apply it multiple times for maximum hydration or use it as the first step to boost overall skincare results, with visible improvements in as little as 4 weeks.
Now available on Costco.com, this exclusive bundle is expected to sell out fast, as the peptide serum is a fan favorite known for its high demand. Costco members are encouraged to act quickly, as the set is available only on a first-come, first-served basis.
