Description

Volassom CaHA (0.8mL x 2) — Calcium Hydroxyapatite Volumizing Biostimulator

Volassom CaHA is a calcium hydroxyapatite (CaHA) dermal filler from CGBio Inc. in Seoul, South Korea. CGBio built the product on more than 30 years of Apatite research. This is the same technology platform behind the company’s FDA-approved bone graft product, Bongros.

Unlike hyaluronic acid fillers, Volassom works as a dual-action product. It delivers immediate volume on injection, while its CaHA microspheres act as a scaffold that stimulates the body’s own collagen and elastin production over time.

At a Glance

Active Ingredient	Calcium Hydroxyapatite (CaHA) — 30%
Gel Carrier	Carboxymethylcellulose, glycerin, water — 70%
Microsphere Size	Approximately 30 μm
Packing	2 × 0.8mL syringes per box
Manufacturer	CGBio Inc., Seoul, South Korea

Main Benefits

• Immediate volumizing effect: CaHA microspheres provide structural support right after injection
• Long-term collagen stimulation: acts as a scaffold that encourages the body’s own collagen and elastin synthesis
• Lattice-pore technology: supports gradual, even breakdown and reduces the risk of lumpiness or migration
• No skin test required: fully synthetic and biocompatible, with no animal-derived components
• Clinically studied: evaluated in a 2025 peer-reviewed trial for midface volume restoration and skin quality

What’s Inside

Active Ingredient	Calcium Hydroxyapatite microspheres — 30%
Gel Carrier	Carboxymethylcellulose, glycerin, water — 70%
Format	Pre-filled syringes

How Volassom Works

Volassom’s CaHA microspheres use a patented Lattice-pore structure. Under this process, each particle forms circular, layered scales, similar to fish scales, with small pores running throughout. Because of this structure, the particles break down gradually, layer by layer, rather than all at once. As a result, this reduces the risk of uneven absorption or filler migration.

Once injected, the microspheres provide immediate structural support and volume. Over time, they also act as a scaffold, stimulating fibroblasts to produce new collagen and elastin. As the gel carrier gradually biodegrades, newly formed collagen replaces it. This extends the aesthetic effect well beyond the material’s own breakdown timeline.

Clinical Evidence

A 2025 study published in the Journal of Cosmetic Dermatology evaluated Volassom in 15 participants with moderate midface volume deficiency. Researchers tracked volume restoration alongside skin barrier function, hydration, and elasticity over 24 weeks. Assessments took place at baseline and at 2, 4, and 24 weeks. Clinicians at Seoul National University Hospital and Asan Medical Center conducted the study.

Who Volassom Suits

Practitioners recommend Volassom for patients interested in:

• Correcting moderate-to-severe facial wrinkles and folds
• Restoring midface volume in the cheeks, temples, and jawline
• Improving skin tone, hydration, and elasticity over time
• Non-surgical facial contouring and lifting
• Rejuvenating the neck, décolleté, and hands

Administration

Practitioners typically inject Volassom into the mid-to-deep dermis or subcutaneous layer, depending on the treatment goal. Because the product doesn’t include lidocaine itself, some practitioners pair it with a separate local anesthetic to support a more comfortable procedure. Treatment outcomes vary, and additional sessions may be needed depending on the size of the area being corrected.

Duration

The CaHA microspheres themselves typically dissolve within about 12 months. However, because the scaffold stimulates ongoing collagen and elastin production, the overall aesthetic effect often extends well beyond this, commonly reported between 18 months and 2 years.

Precautions

• Avoid in areas with active skin infection or inflammation

Storage & Handling

• Store between 2°C and 25°C
• Protect from direct sunlight
• Single-use only — do not reuse or resterilize

Frequently Asked Questions

What is Volassom CaHA?
Volassom CaHA is a calcium hydroxyapatite dermal filler and biostimulator from CGBio, providing both immediate volume and long-term collagen stimulation.

How is Volassom different from hyaluronic acid fillers?
Volassom is calcium-based rather than HA-based. Beyond providing immediate volume, its microspheres act as a scaffold that stimulates the body’s own collagen and elastin production, which HA fillers don’t typically do to the same degree.

How long do results last?
The CaHA material dissolves within about 12 months, but the collagen-stimulating effect often extends the overall result to 18 months or longer.

Is a skin test required before treatment?
No. Volassom is fully synthetic, biocompatible, and contains no animal-derived components, so it doesn’t require a skin test beforehand.
