Instead of just filling the outside, we fill it up layer by layer, starting from the inside.

Radius

Radiesse


As we age, our skin becomes thinner and loses elasticity—and it’s not just because of a single wrinkle. As collagen in the dermis and the supportive structures that hold the skin in place both diminish, the skin’s core itself weakens.

The main ingredient in Radius, CaHA (calcium hydroxyapatite), is a mineral found in both bones and teeth. Once the microspheres suspended in the gel settle into the dermis, the gel creates immediate volume, and the microspheres stimulate fibroblasts to produce new collagen.

So it begins to fill up immediately after injection, and even after the gel is absorbed , collagen continues to build up over several months. CaHA breaks down into calcium and phosphate ions over time and leaves no residue in the body.

About Radiesse

How does CaHA, the main ingredient in Radius (
), work within the skin?

CaHA Microspheres
01

What is CaHA?

The main ingredient in Radius , CaHA,is calcium hydroxyapatite, which is the same mineral that makes up our bones and teeth. Smooth, spherical microspheres with a diameter of 25–45 μm are evenly dispersed in a sodium carboxymethylcellulose (CMC) gel.

It consists of approximately 30% microspheres and approximately 70% gel carrier. Unlike PLLA, which can cause irritation due to its coarse particles, CaHA has a smooth, uniform spherical shape that settles naturally at the injection site.

Immediate dual action for volume and collagen production
02

Instant volume and collagen at the same time

Immediately after injection, the CMC gel fills the treatment areato create instant volume. The gel is naturally absorbed over several weeks, and the CaHA particles remaining in the area stimulate fibroblasts, inducing the production of collagen (types I and III), elastin, and proteoglycans.

It produces immediate results, and subsequent changes continue much like those caused by a collagen stimulator. The biggest difference from hyaluronic acid fillers is that even after the gel is absorbed, newly formed tissue fills the space.

Changes in Dermis ThicknessCriteria+12%+27%Before the ProcedureFour months laterSeven months laterChanges in Dermal Thickness (Ultrasound Measurement)
03

The thinned dermis thickens from the inside out.

Skin that has thinned due to frequent treatments, aging, and external irritants begins to plump up again starting from the dermis. Ultrasound measurements showed that dermal thickness increased by approximately 12% four months after treatment and by approximately 27% seven months later.

This information is based on clinical data from the manufacturer (Merz); actual results may differ from those shown in the study. Individual results and the rate of change may vary.

How It Works

How Radius Works

1

Inject Radius evenly into the lower dermis and the subcutaneous layer

Phase 1 InjectionEpidermisDermisSubcutaneous layerOn the day of the procedure
2

The gel is absorbed within a few weeks, and collagen forms around the remaining microspheres

Stage 2 Collagen ProductionEpidermisDermisSubcutaneous layerOrder – Several months
3

CaHA breaks down into ions and disappears, and
the newly formed collagen remains in its place.

Treatment Areas

Radius Treatment Areas

Focusing on areas where elasticity has decreased and the skin has thinned, the solution is injected evenly in layers and in appropriate volumes

Nasolabial Folds
Marionette
Wrinkles on the Back of the Hand
Neck Wrinkles

The injection method varies depending on the treatment area and the desired outcome. For areas requiring volume, such as sunken cheeks, the undiluted solution is injected deeply; for improving fine lines, skin texture, and elasticity, the solution is diluted with saline and lidocaine and injected broadly into the superficial layers.

There are certain areas where Radius is not administered. For areas with thin skin or significant movement—such as the lips, lip contours, eyelids, and under-eye area—the particles may be visible through the skin, so we recommend alternative treatments.

Product

Radius Product Information

We fully disclose the ingredients and composition of the products we use.

Product Name
Radiesse®, Merz Aesthetics
Item Name
Biomaterial for Tissue Repair, 1.5 mL Prefilled Syringe
Key Ingredients
Calcium hydroxyapatite (CaHA)
Composition Ratio
Approximately 30% CaHA microspheres + approximately 70% CMC gel
Microsphere Size
Smooth, spherical particles ranging from 25 to 45 μm
Injection Layer
Subdermal layer, subcutaneous layer — Administer as is or diluted, depending on the purpose
Use Diluted
When used to improve skin quality and elasticity , mix (dilute) with saline solution and lidocaineand inject broadly into the superficial layer.
Mechanism of Action
Immediate volume enhancement from CMC gel + collagen synthesis(Types I and III), elastin, proteoglycans, and neovascularization stimulated by CaHA microspheres
Sustained Regenerative Effects
Continues to produce regenerative components such as collagen and elastin for more than 7 months (according to the manufacturer)
Maintenance Period
Effects last for approximately 2 years or more (results may vary)
Disassembly
Through normal metabolic processes ,it is broken down into calcium ions and phosphate ionsand does not remain in the body.
Permit
Approved by the U.S. FDA (2006) and authorized by the Korean Ministry of Food and Drug Safety (KFDA) — Used in approximately 80 countries worldwide
When the procedure is difficult
Infection at the treatment site, hypersensitivity to foreign substances, connective tissue disorders, autoimmune diseases, tendency to develop keloids, pregnancy, or breastfeeding

Radius serves a different purpose than hyaluronic acid fillers.
Fillers add volume by injecting a foreign substance, which is absorbed by the body after several months, but Radius provides immediate volume while stimulating the growth of your own collagen, resulting in longer-lasting results.

Recommended For

We recommend this to people like this

For those whose overall skin elasticity has begun to decline

For those who feel hesitant about getting dermal filler treatments

People whose entire face appears sunken and shadowed

For those who prefer long-lasting results over a strong, one-time effect

Not only the results, but also the difference in experience

The Episode Difference

Why It's Different

Every process has its own unique reason.

01

As Is - To Be - Design

Volume Analysis

First, we assess which areas have lost elasticity and volume, and then
based on the desired appearance,
we determine the injection depth, volume, and dilution ratio for each area.

ANALYSIS

02

Check the exact product and quantity right before your eyes at
.

Verify Authenticity and Capacity

Radius is administered using pre-filled syringes. We verify the genuine product label before opening the package, and transparently disclose the dosage used.

RELIABILITY

03


, change becomes clearer when it is documented.

Online Treatment Report

Since collagen is produced slowly over several months, it’s hard to notice any changes in your face, which you see every day. We record the products used, the treatment areas, the injection volume, and the dilution ratio in an online report to serve as a benchmark for evaluating Radius’s effectiveness.

Notice

Please follow these guidelines after your procedure.

  • 1

    Immediately after the procedure, you will notice an immediate increase in volume due to the gel filler. As the gel is absorbed over the course of several weeks, the volume may feel as though it has decreased slightly; this is a normal part of the process as collagen builds up.

  • 2

    To ensure the treated area settles smoothly, gently massage it as directed. If you feel any tightness, gently press and smooth it out in a circular motion.

  • 3

    Apply a cold compress to the treated area. Wrap the ice in a towel or similar material to prevent it from coming into direct contact with your skin.

  • 4

    Please avoid alcohol, strenuous exercise, saunas, and steam rooms for 24 hours after the procedure. Doing so may cause swelling and bruising to worsen.

  • 5

    Swelling usually subsides within 2–3 days, and bruising typically fades within 1–2 weeks. You can cover the injection marks with makeup starting the next day.

  • 6

    Collagen gradually increases over a period ranging from several weeks to several months after the procedure. It is natural for these changes to occur gradually over time rather than all at once.

  • 7

    If you notice any lumps, persistent pain, or redness at the treatment site, please contact the hospital. While these symptoms usually improve with observation, they require medical evaluation.
