Kiehl's, a skincare brand born in 1851 as a small apothecary in New York's East Village, will launch the "3D Plump & Glow Serum" on September 4, 2026, designed to lead to a "plump and glowing" complexion filled with happiness. For over 170 years since its founding, Kiehl's has accumulated dermatological knowledge and consistently proposed cutting-edge skincare. This time, the brand focuses on early slow aging, addressing the gradual changes in skin that occur after the age of 20. Collagen, essential for skin firmness and elasticity, decreases by approximately 1% each year after peaking at age 25. However, due to its large molecular size, collagen often remains on the skin's surface when simply applied, making it difficult to fully exert its effects. Kiehl's has tackled these two challenges head-on with advanced proprietary technology that pursues "speed and precision" to the extreme. The result is the "3D Plump & Glow Serum," developed with inspiration from the diverse functions of 15 types of collagen. The key ingredient is "Next-Generation Collapceptide*2," which replicates the skin's natural collagen structure using advanced biotechnology. It is equipped with "Double Action Liposome Technology" that instantly breaks through the skin's surface barrier and rapidly delivers the ingredient to every corner of the stratum corneum. Like a two-stage rocket, it efficiently works on the skin in two stages. Furthermore, it employs precise delivery technology akin to GPS. Kiehl's unique design achieves an approach that not only applies ingredients but also efficiently delivers them to targeted areas. *1 To the stratum corneum *2 Synthetic Human Recombinant Polypeptide-69, Synthetic Human Recombinant Octapeptide-69 (both skin-conditioning ingredients) Faster and more precise delivery to targeted areas! 1.
