Cellerdium vs. Rejuran,

They answer sunken faces differently

Let me start with the conclusion.

Cellerdium and Rejuran are

grouped under the same skin booster,

but one replenishes collagen

and the other stimulates regeneration.

They are completely different types of treatment.

I’ll explain why in this article.

Similar only in name,

they actually belong to different categories

Cellerdium is a skin booster in the

'collagen filler' category that directly injects human-derived collagen.

Rejuran contains salmon DNA fragments to

stimulate the skin’s own

regeneration.

Cellerdium is the one that 'directly fills in the material,' and

Rejuran is the one that

'kicks the skin into making it itself.'

Why do results differ

even though they are the same skin booster?

"If your face feels hollow because you’ve lost facial volume, Cellerdium is better.

If improving skin texture and elasticity is the priority,

Rejuran is the better choice.

See whether you lack material

or lack signals."

— Dr. Wi Young-jin (Beautystone Clinic, Hongdae)

Rejuran’s PN component stimulates fibroblasts

and sends signals to make new collagen.

In the end, the result is created by 'your own skin.'

By contrast, Cellerdium

directly lays down purified collagen.

By filling the empty space with material,

volume rises immediately.

A 41-year-old woman recently came in for a consultation,

saying the area below her cheekbones had sunk in deeply,

and she was considering four Rejuran sessions.

For someone like this,

Cellerdium gives the answer in one treatment rather than Rejuran.

If the direction is off,

even four sessions won’t feel satisfying.

Cellerdium vs. Rejuran,

See which one applies to you

If you already have enough facial volume but

your skin is rough and your pores have become lax,

Rejuran is much better than Cellerdium.

Conversely, if you’re concerned about both hollowness and elasticity,

people also combine the two for a synergistic effect.

The three questions we hear most often in the consultation room

Q1. Can I have both treatments?

Won’t the effects overlap?

No, the two treatments complement each other.

Filling volume with Cellerdium

and boosting regeneration with Rejuran

creates much higher satisfaction than doing only one.

Q2. Between cost and number of sessions,

which side is more burdensome?

Cellerdium tends to show immediate changes in 1–2 sessions,

so total cost is relatively easy to predict.

Rejuran is usually planned with four sessions,

so cumulative cost can be higher.

Q3. I have sensitive skin— which is safer?

If you have severe redness and are easily irritated,

Cellerdium is less irritating.

As PN settles in, Rejuran may cause

temporary redness or

embossing that can last for a few days, so

be sure to check your condition.

If you take away just one thing today,

— first figure out whether your face has 'run out of material'

or whether the 'signals have stopped'

and distinguish that first.

In the next article,

I’ll explain 'how to plan the interval for the Cellerdium and Rejuran combo.'

This was Dr. Wi Young-jin.

Frequently asked questions

Q. Can I have both treatments? Won’t their effects overlap?

A. No, the two procedures complement each other. Satisfaction is much higher than when only one is performed.

Q. Which is more of a burden, the cost or the number of sessions?

A. Cellredium tends to show noticeable changes after just 1–2 sessions, so the total cost is relatively easy to estimate. Rejuran is usually planned as a 4-session treatment, so the cumulative cost can be higher.

Q. I have sensitive skin— which option is safer?

A. If you have severe redness and are sensitive to irritation, Celdyem is gentler.

Q. Is there a difference in how long it takes to see the effects of Cellederm versus Rejuran?

A. Yes, they are different! CelluDiem directly replenishes collagen, so you can see immediate changes right after the procedure up to two weeks. Rejuran, on the other hand, stimulates your skin to regenerate itself, so you will gradually feel the difference usually around the third session.
