CollaJu: Injectable Collagen Regeneration for Natural Skin Repair

At SKNN Clinic, we're selective about the treatments we offer. New doesn't always mean better. Every treatment we introduce must meet three standards: clinically proven results, natural-looking outcomes, and support for long-term skin health—not just temporary fixes.

CollaJu is one of those rare treatments that checks every box.

Launching at SKNN in 2026, CollaJu is a premium injectable atelocollagen treatment from South Korea, designed to restore skin structure, improve firmness, and stimulate your body's natural collagen production from within.

What is CollaJu?

CollaJu is an injectable Type I atelocollagen—a medical-grade treatment used in aesthetic and regenerative dermatology. Unlike traditional dermal fillers that primarily add volume, CollaJu works differently: it replenishes collagen directly within the skin while encouraging your body to produce more over time.

The collagen in CollaJu is highly purified atelocollagen, processed to remove telopeptides—the components most often linked to allergic reactions. This purification makes CollaJu highly biocompatible and structurally similar to human collagen.

In simple terms: CollaJu helps your skin repair itself by restoring what naturally declines with age—healthy, supportive collagen.

How Does CollaJu Work?

CollaJu works through three complementary mechanisms:

1. Immediate Collagen Replenishment

Once injected, the liquid collagen provides instant structural support. You'll notice immediate smoothing of fine lines, softening of wrinkles, and improved skin texture.

2. Natural Collagen Stimulation

CollaJu acts as a biological scaffold, encouraging fibroblasts (your skin's collagen-producing cells) to create new collagen and elastin. This means your skin continues improving gradually after treatment—becoming firmer, more elastic, and better hydrated over time.

3. Skin Regeneration & Integration

Rather than sitting rigidly in the tissue like some fillers, CollaJu integrates naturally into the dermis. This supports ongoing tissue regeneration, improves skin density, and enhances overall skin quality without stiffness or an unnatural feel.

How is CollaJu Different from Traditional Fillers?

CollaJu is for patients who want improvement, not transformation.

Unlike hyaluronic acid fillers, CollaJu:

• Doesn't create sharp projection or contour—it works within the skin, not on top of it

• Feels soft and natural—no stiffness or heaviness

• Avoids the "filled" look—results are subtle and refined

• Focuses on skin quality and structure, not just added volume

This makes it particularly suitable for delicate areas like under the eyes, and for patients seeking natural rejuvenation rather than dramatic change.

What Areas Can Be Treated with CollaJu?

CollaJu is versatile and ideal for areas where skin quality, firmness, or structure has declined:

• Fine to deep wrinkles (smile lines, forehead lines, marionette lines)

• Under-eye hollows and crepey under-eye skin

• Areas of mild to moderate skin laxity

• Dull, dehydrated, or thinning skin

• Any zone requiring structural repair rather than lift or contour

Your SKNN doctor will assess your skin carefully and recommend the most appropriate treatment plan for your individual needs.

Who is CollaJu Best For?

CollaJu is ideal if you:

• Want natural-looking rejuvenation that still looks like you

• Are concerned about fine lines, wrinkles, or loss of firmness

• Prefer skin repair and regeneration over visible volume

• Haven't enjoyed the feel or appearance of traditional fillers

• Are focused on long-term skin health, not just quick fixes

CollaJu can be used alone or as part of a comprehensive collagen-support strategy, depending on your goals.

Safety & Regulatory Standards

CollaJu is a Class IV medical device with regulatory approvals including KFDA (Korea), CE (Europe), and NMPA (China). It's manufactured using a patented purification process designed to ensure safety, consistency, and biocompatibility.

As with all injectable treatments at SKNN, CollaJu is only administered after a thorough consultation and by trained medical professionals.
