Restores volume and stimulates collagen
A calcium-based collagen stimulator
RADIESSE is a calcium-based filler made with calcium hydroxylapatite (CaHA). As its fine particles gradually break down in the skin, they stimulate your own collagen production, smoothing wrinkles and improving firmness, skin tone, and texture.
The particles are uniform spheres with smooth surfaces. Over time, they break down into calcium and phosphate ions, leaving no residue in the body. RADIESSE is approved for use in more than 80 countries worldwide.

Hollow cheeks, wrinkles, neck lines: what this filler improves
Lines and wrinkles
Softens nasolabial folds and lines around the mouth and neck. The calcium particles and gel immediately fill hollows, while newly formed collagen provides support beneath the wrinkles over time.
Firmness
Makes skin firmer and tighter. The calcium particles act directly on fibroblasts to stimulate type I and III collagen and elastin production.
Skin tone
Brightens dull skin. As the particles break down, collagen and new blood vessels increase, improving the condition of the dermis.
Skin texture
Smooths rough skin texture. A diluted form can be spread across a broad area in a superficial layer to increase collagen density evenly throughout the skin.
Volume
Naturally restores volume to hollow cheeks. The spherical calcium particles provide immediate volume, which your own collagen gradually helps maintain.
Collagen density
Thickens the dermis and firms the skin by increasing collagen, elastin, proteoglycans, and new blood vessels together.

Patient experiences: natural volume for hollow cheeks

Fuller, but still natural
I had RADIESSE because I was bothered by lost cheek volume and lines that showed when I smiled. After treatment around my cheeks, mouth, and jaw, my face looked a little fuller. What I liked most was that the treated areas didn't look overfilled and still looked natural.
My cheeks have their volume back!
My RADIESSE treatment covered my smile lines and jaw area as well as my cheeks. Afterward, my cheeks looked fuller and the lines around my mouth were less noticeable. I was happy with how natural it all looked, without any one area standing out.
More definition, with a natural result
I tried RADIESSE to improve my smile lines and restore volume to my cheeks. With more fullness in my cheeks and around my jaw, my face looked a little more defined. I liked the change, but how natural it looked was what stayed with me most.

How the ingredients differ
The product and injection technique depend on whether your priority is volume, firmness, or skin texture.
| Type | Main ingredient | How it works | Concerns to discuss |
|---|---|---|---|
| RADIESSE | CaHA | Immediate volume restoration followed by gradual collagen production | Hollow cheeks · Lines around the mouth · Firmness |

| PDLLA/HA collagen stimulator | PDLLA + hyaluronic acid | Hydration and gradual collagen production | Skin texture · Fine lines · Firmness |
How it restores volume and builds collagen
Your doctor explains how it works
How do calcium particles stimulate collagen? Initial volume restoration is followed by tissue regeneration. Your doctor, who also teaches these techniques to other physicians, determines the dilution, injection depth, and amount for your face.
Initial volume
Fine spherical calcium particles and gel add volume at the injection site.
Fibroblast stimulation
The calcium particles act directly on fibroblasts, signaling them to regenerate tissue.
Tissue regeneration
Type I and III collagen, elastin, proteoglycans, and new blood vessels develop.
Gradual breakdown
The particles break down into calcium and phosphate ions and are eliminated from the body.

The doctors at Dong-An Joongsim ClinicCommon questions: side effects, results and prices
Answers from our doctors
How do I choose a RADIESSE clinic in Apgujeong, Gangnam, Seoul?
Results depend on how treatment is planned and performed. Check whether a doctor personally consults with you and performs your treatment, whether the clinic uses genuine products and supplies, and whether it can combine treatments to suit your face. Our doctors at Dong-An Joongsim Clinic in Apgujeong, Gangnam, Seoul, Korea have been recognized as Outstanding RADIESSE® Trainers. We take time with every patient. A doctor handles your consultation and performs your treatment personally.
How is RADIESSE different from other fillers?
RADIESSE is a calcium hydroxylapatite (CaHA) filler. While conventional hyaluronic acid fillers focus on adding volume, it also stimulates collagen as its calcium particles gradually break down, improving firmness and skin texture.
What is a RADIESSE skin booster?
A RADIESSE skin booster uses the product diluted and distributed across a broad area in a superficial layer. The aim is to increase collagen density evenly throughout the skin to improve firmness, texture, and neck lines, rather than add volume. Diluted CaHA is also covered in international expert consensus recommendations.
When will I see RADIESSE results, and how long do they last?
Hollow areas fill out immediately after treatment, while collagen production continues over several months. Volume changes are visible right away; improvements in firmness and skin texture become more noticeable after a few months. Manufacturer data reports results lasting more than two years.
What side effects can RADIESSE cause?
Temporary bruising, swelling, or lumps may occur but settle within a few days. Avoid touching or irritating the treated area for about one week, and avoid saunas and strenuous exercise during that time.
Does RADIESSE stay in the body?
No. The calcium particles break down into calcium and phosphate ions through the body's normal metabolic processes.
How is the price of RADIESSE treatment determined?
The price depends on the area treated, the amount used, and whether the product is used to restore volume or diluted for a broader skin booster treatment. Your doctor will explain the price along with a treatment plan for your face after examining you.
Can RADIESSE be used outside the face?
It can also be used for neck lines and on the décolletage, backs of the hands, and knees.
Can I return to my usual routine right away?
Yes, you can return to your usual activities immediately. Avoid saunas and strenuous exercise for one week.
