Radiesse: Is It the Same as Hyaluronic Acid?

Half of the patients who come for Radiesse think it's the same as hyaluronic acid

As we enter the changing season, my clinic

is starting to get busy again with patients saying

"My cheeks seem to have sunken dramatically."

"I want to get filler,

but I don't want it to look obvious

and I want something long-lasting"

I hear this from so many patients.

That's why Radiesse inquiries have increased significantly lately,

but when I actually consult with them,

surprisingly few people properly understand

what kind of filler this is.

Today, I'd like to explain this in detail.

They may look similar, but the key difference is important

Radiesse is an injectable filler made from

a mineral component called calcium hydroxyapatite (CaHA).

Unlike commonly known hyaluronic acid fillers

like Restylane and Juvederm,

Radiesse's main component is

calcium-based minerals that are also found

in our bones and teeth.

So the way it works

and the way it dissolves are different.

Understanding this difference makes choosing easier

Key Point of This Article

Radiesse, with its calcium hydroxyapatite component, provides immediate volume while stimulating collagen production.

It's a product that combines the benefits of both filler and skin booster.

The real appeal of Radiesse is that

it performs the roles of both

"filler" and "skin booster" at once.

When calcium hydroxyapatite particles

are injected, they immediately provide volume,

while surrounding tissues recognize these particles

and start producing new collagen.

In other words, on the day of injection

you'll immediately feel the sunken areas filling up,

and after 2-3 months, the skin itself

becomes firmer with improved elasticity—

it's a dual-action structure.

Last month, a 47-year-old woman came to me saying,

"I've had hyaluronic acid filler

in my cheeks four times at another clinic,

but it goes back to normal after just 6 months."

Upon examining her skin, rather than volume loss,

the skin itself had become thinner and sagged.

For patients like this, I recommend Radiesse,

usually diluted 1:1 or 1:2

using the hyperdilute technique

to spread it widely like applying cream.

After about 3 sessions like this,

quite a few patients tell me

"It feels like my skin went back 10 years."

Hyaluronic acid draws in moisture

to "fill" volume,

while Radiesse is closer to

"rebuilding" the skin.

In terms of duration,

while hyaluronic acid fillers last an average of 9-12 months,

Radiesse maintains its effects for about 12-18 months.

Dr. Wi Young-jin's Key Summary


Radiesse should be approached not as


"a filler to fill sunken areas" but as


"a procedure to rebuild the skin."



Immediate volume + long-term collagen regeneration—


this is the first option I suggest to patients


who want both benefits simultaneously.

This is how I categorize cases in my clinic

The approach for Radiesse varies quite a bit

depending on each case.

For some patients, I inject the concentrate deeply,

for others, I dilute it and spread it widely.

Not understanding this distinction leads to significantly different results.

But this isn't always a good thing.

Due to Radiesse's particle characteristics,

once injected, unlike hyaluronic acid,

it cannot be reversed with

a dissolving agent (hyaluronidase).

That's why we don't use it in

thin and sensitive areas like lips or under-eyes,

and if the injection layer and amount are misjudged,

nodules (lumps) can form.

However, when a practitioner

accurately understands anatomy and

selects appropriate indications,

it can create changes in skin quality itself

that cannot be achieved with hyaluronic acid.

The three most common questions in my clinic

Q1. Is Radiesse immediately noticeable? I really hate obvious results.

A. If we inject the concentrate into deep layers,

you may look slightly swollen on the day of treatment,

but it becomes natural within 2-3 days.

The diluted, widely-spread technique

is barely noticeable from day one.

The change is more like

"I don't know what you did, but your face looks brighter."

Q2. How many sessions do I need, and how long does it last?

A. For volume purposes,

one session is often sufficient,

and the average duration is 12-18 months.

For skin quality improvement (hyperdilute) purposes,

we proceed with 2-3 sessions at 4-6 week intervals,

and in this case, the collagen production effects

can last over 2 years for some patients.

Q3. What are the side effects? I heard nodules can form.

A. The main concern is

the nodules you mentioned.

Injecting into thin skin, highly mobile areas,

or too close to the epidermis

can create palpable lumps.

That's why maintaining anatomically safe layers

is important,

and for about a week after treatment,

it's best to avoid vigorous facial massage

or sleeping face-down.

Rarely, vascular complications have been reported,

so I recommend receiving treatment

from practitioners skilled in anatomy.
