Kiehl's New "3D Plump & Glow Serum" Launches September 4 (Fri) with Dermatological Expertise! Speeding Penetration*1 for a "Plump & Glow" Finish!

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.

Faster and more precise delivery to targeted areas!

1. "All-Around Collagen Formula" inspired by 15 types of collagen

Kiehl's focused on the diverse functions of 15 types of collagen, including "baby collagen," which is abundant in young skin. The key ingredient, "Next-Generation Collapceptide*1," developed using advanced biotechnology, integrates into the skin as if melting the moment it's applied. Additionally, "Power Collagengine*2" and "Pink Vitamin*3" enhance the overall formula, leading to dense, firm skin that bounces back from within.

Next-Generation Collapceptide*1 (Key Ingredient)

This product's "Next-Generation Collapceptide*1" is designed using advanced biotechnology to have the same molecular sequence as human type III collagen, thoroughly pursuing affinity with the skin and rapid effectiveness. It integrates into the skin as if melting the moment it's applied, leading to "plump and glowing" skin.

Power Collagengine*2 (Supporting Key Ingredient)

A proprietary blend centered around the unique active ingredient Pro-Xylane*4, combined with Rhamnose*5 for smooth elasticity and Maitake Mushroom Extract*6 for firmness and radiance. It leads to a dense firmness that bounces back from within.

Pink Vitamin*3 (Supporting Ingredient)

A supporting ingredient that leads to a vibrant, radiant impression. It contains the component that gives the texture its vivid pink color.

2. "Advanced Technology" pursuing "Rapid Penetration*7" and "Precision Delivery"

◎ "Double Action Liposome" that works on the skin in two stages

In this formula, "Next-Generation Collapceptide*1" is equipped with "Double Action Liposome" technology, similar to a two-stage rocket. While stably encapsulating the ingredients, it instantly breaks through the skin's surface barrier and pushes deeper, efficiently bringing out the power of ingredients that are difficult to exert with simple application.

◎ GPS-inspired Precision Delivery Technology

No matter how much you replenish, it's meaningless if it doesn't reach the target area. Kiehl's has thoroughly pursued delivering key ingredients*1 to "targeted areas," achieving precision delivery like GPS.

Furthermore, by applying analytical technology used in medical fields, they have succeeded in visualizing the penetration pathway. This delivers uncompromising results.

For those who are "skincare lost" Introducing the new standard: "Colla-Savings" for your future skin

Trendy ingredients, a constant stream of beauty advice.

"In the end, what does my skin really need?" Are you feeling lost?

In fact, collagen, which supports skin firmness and elasticity, decreases by about 1% each year after peaking at age 25. Even if you think "I'm still okay," the foundation of your skin is gradually changing.

Kiehl's focuses on "collagen savings" as a smart investment in your future self. Just like investing or NISA, consistently build up your skincare routine for future skin and care for firmness and elasticity. This is a proposal for essential and smart anti-aging care*1 that doesn't get swept away by fleeting trends.

HOW TO USE

"Plump & Glow Prep" before makeup in the morning Create a "plump and glow" impression before makeup by layering a "plumpness" that catches the light.

The light texture that penetrates the skin as if it's drinking it allows for comfortable use in morning skincare and before makeup. It provides natural firmness and radiance to the skin, creating beautiful bare skin. From daily use to special occasions, it creates a vibrant and happy "plump and glowing" complexion.

"Colla-Savings" for future skin with nighttime skincare Turn your nighttime skincare into "colla-savings" time for your future skin.

While addressing skin that looks "somewhat tired" due to dryness or lack of radiance, daily accumulation leads to skin that feels firm and resilient from within.

It achieves care that looks not only at the "current plump and glow" but also at the skin of the future.
