Kiehl’s Introduces Power Plump 1CC Collashot™ Serum—A Breakthrough Collagen Formula Designed to Restore Visible Volume

New serum from Kiehl’s uses patented collagen technology to visibly plump, firm, and smooth skin—including concerns associated with GLP-1-related volume loss.

Kiehl’s is taking collagen skincare in an exciting new direction with the launch of Power Plump 1CC Collashot™ Serum, an innovative treatment formulated to visibly restore skin’s bounce, firmness, and youthful-looking volume.

Powered by patented collagen technology and an advanced delivery system, the new serum is designed to help address multiple visible signs of collagen loss—including concerns increasingly experienced by people using GLP-1 medications that can contribute to facial volume changes.

It’s one of Kiehl’s most science-driven launches yet, bringing dermatologist-inspired innovation to everyday skincare.

What Makes It Different

Patented Surra-Liposome™ Technology

One of the standout innovations behind Power Plump 1CC Collashot™ Serum is Kiehl’s proprietary Surra-Liposome™ delivery technology.

Rather than allowing collagen-supporting ingredients to remain on the skin’s surface, this advanced encapsulation system helps deliver the formula through multiple surface layers of the skin for more effective absorption.

The goal is simple: maximize ingredient performance where skin needs it most.

Recombinant Collagen Polypeptides

Instead of relying on traditional collagen ingredients that sit on the surface, Kiehl’s developed patented recombinant collagen polypeptides engineered to help support skin’s natural collagen network.

Combined with hydrating and barrier-supporting ingredients, the formula helps skin appear:

• visibly plumper
• firmer
• smoother
• more resilient

without feeling heavy or greasy.

Clinical Results

According to Kiehl’s clinical testing, Power Plump 1CC Collashot™ Serum helped improve 16 visible signs associated with collagen decline, including:

• Loss of firmness
• Reduced elasticity
• Fine lines
• Wrinkles
• Skin roughness
• Overall texture
• Visible volume

The lightweight serum is designed for consistent daily use and layers easily beneath moisturizer and sunscreen.

Why This Launch Matters

Collagen-supporting skincare continues to evolve, but this launch arrives at a particularly important moment.

As GLP-1 medications become more widely used, dermatologists have increasingly discussed the visible facial volume changes that some users experience after rapid weight loss. While skincare can’t replace lost facial fat or act like a filler, formulas that support hydration, firmness, and the appearance of collagen-rich skin are becoming an important part of many skincare routines.

Kiehl’s is one of the first prestige beauty brands to directly acknowledge this emerging skincare concern, positioning Power Plump 1CC Collashot™ Serum as an innovative option for anyone noticing skin that looks less plump, less firm, or more hollow over time.

Of course, the serum isn’t just for GLP-1 users. Anyone experiencing natural collagen decline from aging may benefit from its skin-plumping, smoothing, and firming approach.

I’ve just begun testing Kiehl’s Power Plump 1CC Collashot™ Serum and was excited to receive an early editor’s sample ahead of launch. The serum has a silky, lightweight texture that absorbs quickly without feeling sticky, making it easy to incorporate into both morning and evening routines.

I’ll continue testing it over the coming weeks and update this story with my long-term results, including how it performs on firmness, hydration, and overall skin appearance.

How to Get the Best Results

For best results, apply Power Plump 1CC Collashot™ Serum to clean skin morning and evening.

Follow with your favorite moisturizer to help lock in hydration, and always finish with a broad-spectrum sunscreen during the day to protect collagen from UV damage.

Consistency is key—collagen-supporting skincare delivers its best visible improvements with regular use over time.
