Understanding the Bio-Compatibility and Longevity of OTESALY® CaHAfill LD

This "endogenous" nature provides CaHA with two core clinical advantages:

• Superior Biocompatibility: As a biocompatible filler, it is naturally recognized by the body. It eventually metabolizes into harmless calcium and phosphate ions, ensuring an extremely low allergy rate and seamless tissue integration.
• Dual-Action Aesthetic Logic: Unlike a standard hyaluronic acid filler that simply adds volume, CaHA acts as a powerful collagen stimulator. It triggers fibroblasts beneath the skin to produce fresh, new collagen. This results in structural support that is regenerated from within, making it a truly long-lasting facial filler solution.

Since its clinical application in the mid-1990s, the safety of CaHA has been globally validated. As demonstrated by the industry benchmark Radiesse®, CaHA-based regenerative injection therapy has become a standard growth point for medical aesthetic clinics worldwide. OTESALY® brings this proven regenerative material to the global market, offering your clients a premium, cost-effective, and long-term anti-aging solution.

Part 2: The Innovation — What is OTESALY® CaHAfill LD?

OTESALY® CaHAfill LD is a cutting-edge, sterile, and biodegradable CaHA Dermal Filler designed for those seeking sophisticated facial contouring. It functions as a "hybrid" injectable, effectively bridging the gap between traditional hyaluronic acid fillers and regenerative medicine.

Unlike standard dermal fillers, the unique 3-in-1 formula of OTESALY® CaHAfill LD ensures a superior treatment experience through three synergistic components:

• 30.7% CaHA Microspheres: Acts as a potent collagen stimulator to trigger long-term tissue regeneration and sustained firmness.
• 20mg/ml Cross-linked HA: Provides immediate lifting, volume replacement, and deep hydration for instant gratification.
• 0.3% Lidocaine: Integrated for patient comfort, ensuring a virtually painless and stress-free injection experience.

This semi-solid, latex-free gel is precision-engineered for deep dermal or subdermal injection. It doesn’t just "fill" space—it builds structural support from the inside out.

Part 3: OTESALY® CaHAfill LD's Three Core Attributes

1. Biodegradability & Bio-safety

As a highly biocompatible filler, the porous Calcium Hydroxylapatite microspheres create a temporary 3D scaffold within the skin. This structure allows fibroblasts to colonize and produce natural collagen fibers. While providing immediate filling, the microspheres are designed to safely break down over time into calcium and phosphate ions—natural minerals already present in the body—which are then fully excreted through normal metabolic pathways.

With a composition nearly identical to human bone minerals and an ultra-smooth microsphere surface, it ensures minimal tissue trauma and inflammatory response, making it one of the safest choices for sensitive patients.

2. Regenerative Power & Collagen Stimulation

The surface of the CaHA microspheres provides an ideal attachment site for cells, actively promoting cell proliferation and extracellular matrix secretion. This makes it an exceptionally efficient collagen stimulator, triggering the production of both Type I and Type III collagen. This process revitalizes skin texture and elasticity from within, shifting the focus from simple volume to true biological rejuvenation.

3. Superior Shaping & Structural Support

Compared to traditional hyaluronic acid fillers, OTESALY® CaHAfill LD possesses a higher elastic modulus (G') and viscosity. It acts like "micro-rivets" under the skin, providing unparalleled structural support. It can remain precisely in the injected position without migration, only forming a long-lasting and clear contour for months.

Part 4: OTESALY® CaHAfill LD Clinical Treatment Applications

OTESALY® CaHAfill LD is more than just a filler; it is a high-precision tool for restructuring facial architecture.

1. Advanced Facial Contouring

For clients seeking defined contours, OTESALY® CaHAfill LD is the gold standard for jawline and cheekbone shaping:

• Deep Support: With its extremely high viscoelasticity (G-Prime), it is ideal for periosteal injection, providing bone-like stable support for the cheekbones, brow ridge, nasal base, and mandible.
• Sculpting for Bone Structure: Avoids a puffy appearance, achieving a three-dimensional, natural contour lift, making facial lines tighter and more defined.

2. Hand Rejuvenation

The hands are the second face of aging. In hand rejuvenation treatments, OTESALY® demonstrates unparalleled advantages:

• Immediate Plumping: Quickly fills in the depressions on the back of the hands caused by fat loss, covering visible veins and tendons.
• Skin Improvement: Continuously stimulates collagen regeneration, fundamentally improving the thickness and elasticity of the skin on the hands, restoring delicate and smooth hands.

3. Full-Face Structural Restoration

• Mid-Face Lifting: Improves cheek hollowing and nasolabial folds (smile lines).
• Detail Refinement: Effectively smooths marionette lines and perioral wrinkles.
• Dual Efficacy: While providing physical filling and plumping, it also initiates collagen regeneration.

Quick Guide for Clients

1. Target Areas: Nasolabial folds, marionette lines, cheek/chin augmentation, jawline, neck, and hands.
2. Key Results:

• Enhances contour lines with architectural precision.
• Activates long-term bio-stimulation through Calcium Hydroxylapatite.
• Provides a long-lasting facial filler effect that outperforms standard HA treatments.

Part 5: Treatment Process and Expected Results

A treatment with OTESALY® CaHAfill LD is highly efficient, typically completed in a single session with results unfolding across three distinct phases:

• Phase 1: The Immediate Reveal (Instant Gratification)

Thanks to the integrated hyaluronic acid filler carrier, patients see an immediate lifting and filling effect. Deep folds are smoothed, and hollow areas are instantly volumized. This immediate visible improvement significantly boosts patient satisfaction and confidence right in the clinic.

• Phase 2: The Neo-Collagenesis Period (Weeks to Months)

As the Calcium Hydroxylapatite microspheres begin their bio-inductive work, the body’s natural regenerative process takes over. Acting as a powerful collagen stimulator, it triggers a large-scale production of fresh collagen. During this stage, skin texture, thickness, and elasticity improve progressively, leading to a more refined and youthful glow.

• Phase 3: The Long-Term Maintenance (Years of Youth)

The results of OTESALY® CaHAfill LD are not just impressive—they are enduring. As a truly long-lasting facial filler, the structural improvements can be maintained for 2 to 3 years, depending on individual metabolism and lifestyle.

We recommend a complete course of treatment consisting of 3 sessions, with an interval of 4-6 weeks between each session, to build the most stable and impactful collagen scaffold.
