It's Not AI. [CellRedM vs Re2O], Which Product Is Right for Me? (Usage, Price Comparison)
Hello, I am Dr. Wi Yong-jin, a specialist at Seoul National University.
I'll start by talking about L&C Bio, the company that makes Re2O.
These days, many people are really interested in stocks, right?
The KOSPI fluctuated between 6000 and 5000, haha.
I'm not good with stocks by nature,
so I haven't traded stocks for quite a while,

By the way, lately I’ve been receiving a lot of questions due to these very hot items.
“Doctor, between CellRedM and Re2O, which one is better?”
Human ADM (Human Acellular Dermal Matrix) skin boosters have recently
started to get serious attention, moving beyond the question of “Is it a good treatment?” to
the stage of differentiating between products.
Just like the stock price of L&C Bio, it truly shows how much interest has grown.
When it was first launched in May 2025,
I was cautiously in the position of wanting to “wait and see more clinical data.”
About three months later,
as inquiries increased, we had no choice but to
conduct demonstration treatments and long-term follow-ups directly at our Beauty Stone clinic, and it is now being applied to actual patients.
Today, based on that experience, I will honestly compare three products,
with a focus on CellRedM and Re2O.
First, let's start with what Human ADM is
'Acellular Dermal Matrix' is
a tissue that removes cells from human skin, leaving only structural proteins like collagen, elastin, and glycosaminoglycans (GAGs).
These three components are the extracellular matrix (ECM) that primarily contributes to the skin's elasticity, hydration, and structure.
In a word, it is dermis from another person.
Is this a new category in dermatology?
However, this category is not new.
In plastic surgery, allogeneic dermis (like Megaderm) has been used for decades during burn reconstruction and nose/breast surgeries
to prevent tissue transparency.
Skin boosters have expanded the application of that to 'skin regeneration and elasticity improvement'.
Decisively Different from Existing Skin Boosters
Juvederm·Sculptra·Radiesse >
Inducing inflammation to stimulate collagen production
The efficacy has been proven, but it is true that the inflammation process is involved.
Human ADM has a different approach.
Rather than stimulation, it is a concept of directly supplementing the collagen structure,
resulting in little to no inflammation response and very natural results.
No nodules are formed.
It is dermis itself.
Expected changes include:
Overall improvement in skin texture and tone
Recovery of elasticity
Reduction of pores and fine lines
Relief of inner dryness
Reduction of redness
Supplementation of natural volume
Comparison of the Top Three: Re2O vs CellRedM vs Juvederm
Particle Size | ECM Content | |
|---|---|---|
CellRedM (CellREDM) | 75µm | 160mg |
Re2O (Re2O) | 100µm | 150mg |
Elabie Re2O is manufactured by L&C Bio and sold by Humedics.
It has the most accumulated clinical cases as an original product.
CellRedM is manufactured by Hans Biomed, the first in Korea to be certified by AATB (American Association of Tissue Banks).
With a particle size of about 75µm, it is the finest and has the highest ECM content at 160mg.
The small particles enhance collagen production efficiency,
and smaller needles can be used, reducing pain.
CellRedM vs Re2O, What Are the Criteria for Choosing?
If you're hesitant between the two products, you can consider it based on the volumizing effect.
If you're looking to supplement the volume of sunken areas like the temples,
CellRedM wins with its higher ECM content!
Honest About the Drawbacks
Like all treatments, Human ADM also has its downsides.
Psychological Barrier. Some people feel a sense of rejection because it is 'tissue from another person.' Some mention ethical concerns, but all tissues are strictly managed through a legitimate donation system.
Temporary Embossing. If injected too superficially, a bumpy appearance can occur right after the treatment. However, since it is not an inflammatory nodule, it naturally resolves within a few weeks.
Volume Limitations. It is a different concept from actively increasing volume like hyaluronic acid fillers or Sculptra. If the goal is volume increase, there are more suitable options than ADM.
Price. Typically ranges from 600,000 to 800,000 won, making it a procedure with a barrier to entry.
Conclusion: Who Is It Suitable For?
It is the best procedure for those who want their skin to improve without looking like they’ve had work done.
Since it is a concept of structural supplementation rather than stimulation, it is a good alternative for those who want natural skin improvement after the treatment but are concerned about inflammation responses or nodules.
Of course, there is no treatment that is the answer for all skin types. It is most important to consult fully with the physician regarding your current skin condition, goals, and previous treatment history before making a decision.
