I. What are Hyaluronic Acid injections? A quick overview of their three main categories
The term “hyaluronic acid injections” is well-known in Taiwan, but in fact this name encompasses a variety of different injection formulas and mechanisms of action. Simply put, the skin-enhancing injections currently available on the market can be divided into two main categories:
- PN (Polynucleotides) category: Represented by Rejuran, these products indirectly induce collagen production by stimulating the body’s own fibroblast cells.
- ECM (Extracellular Matrix) category: Represented by RE20 and CellREDM, these products directly replenish the structural components such as collagen, elastin, and glycosaminoglycans that are lost in the dermis.
These two approaches differ in their mechanisms and are suitable for different skin conditions. Next, we will introduce these three products in more detail.
Below are the price ranges for these three products according to the BeautsGO platform

II. Detailed introduction to RE20 (Elravie Re2O)
What is RE20?
RE20, officially named Elravie Re2O, was developed by the Korean company L&C Bio. It is the world’s first clinically approved hADM (Human Acellular Dermal Matrix) hyaluronic acid injection. It can be considered the “pioneer” in the field of ECM hyaluronic acid injections and is widely used in plastic and cosmetic clinics in the Gangnam area of Seoul, South Korea.

Composition and mechanism of action of RE20
The core component of RE20 is collagen ECM derived from human skin. This material undergoes a precise cell-decellularization process, removing cellular components that may trigger immune reactions (such as cells and fat) while retaining only the pure extracellular matrix structure. Its composition closely resembles the natural dermal structure of the human body. The main active ingredients include:
- Collagen: Provides structural support for the skin and enhances firmness
- Elastin: Restores the skin’s elasticity and tensile strength
- Hyaluronic Acid: Provides deep hydration and maintains the water content of the dermis
This “direct supplementation” mechanism is different from the superficial hydration provided by traditional hyaluronic acid injections. RE20 actually delivers these essential components directly into the dermis, allowing the skin to rebuild its structure from within.
The clinical effects of RE20
According to clinical data, the benefits brought by the RE20 treatment are quite diverse:
- Pores shrink by 26.9%
- Fine lines and wrinkles are significantly improved
- Irregularities and dullness of the skin are reduced
- Skin elasticity and firmness are enhanced
- Deep hydration is improved, and the skin’s barrier function is strengthened
It is particularly noteworthy that the effects of RE20 last for a relatively long time; the benefits from a single treatment can last for more than 6 months, especially in terms of reducing enlarged pores and restoring skin elasticity.
Particle size: 100 micrometers
RE20’s hADM particles have a size of approximately 100 micrometers, which is in line with industry standards. There is a slight resistance during application, but overall, the treatment is well-tolerated.

III. Detailed Introduction to CellREDM
What is CellREDM?
CellREDM is manufactured by the Korean company Hans Biome and, like RE20, belongs to the hADM-derived ECM hyaluronic acid injections category. While its core concepts are very similar to those of RE20, CellREDM has been further optimized and upgraded in terms of its formula and administration experience. Currently, CellREDM is considered a “strong competitor” to RE20 at top clinics in Seoul’s Gangnam district; some doctors even refer to it as “the next generation of ECM hyaluronic acid injections.”

Ingredients and Features of CellREDM
Like RE20, CellREDM also uses human dermal matrix derived from adipose tissue. Its main ingredients include:
- Collagen: Supports the structural proteins of the dermis and enhances skin density.
- Elastin: Improves the skin’s elasticity and firmness.
- Glycosaminoglycans (GAGs): Enhance the dermis’ water-retaining capacity and improve skin texture.
Hans Biome possesses over 20 years of expertise in human tissue processing technology. It was the first organization in South Korea to be approved by the MFDS and holds dual certifications from the AATB and the US FDA, ensuring its high credibility in terms of raw material safety and quality control.
The biggest highlight of CellREDM: ultra-fine 75-micron particles
Compared to RE20’s 100-micron particles, CellREDM uses finer 75-micron particles, and this difference brings several significant advantages:
- Less resistance during injection: The smaller particles reduce the resistance encountered when injected into the dermis, making the process smoother.
- More even distribution: These fine particles can be more evenly distributed across various layers of the dermis, resulting in a better covering effect.
- Less discomfort: The overall experience during injection is less uncomfortable, making it particularly suitable for those who are sensitive to pain.
- Less post-injection swelling: The finer particles cause less immediate disturbance to the tissue, leading to faster recovery from any redness or bumps after the procedure.
In terms of its main benefits, CellREDM focuses on improving skin texture and increasing skin density, providing a noticeable “tightening effect from within” after use.
IV. Detailed Introduction to Rejuran
What is Rejuran?
Rejuran, also known as PDRN hyaluronic acid injection or PN hyaluronic acid injection, was developed by the Korean company Pharmaresearch. It is currently one of the most well-known skin-enhancing injections worldwide and enjoys high brand recognition in the Taiwanese and Southeast Asian markets.

Composition and Mechanism of Action of Rejuran
The core component of Rejuran is a polynucleotide extracted from salmon DNA. This DNA fragment is highly compatible with the human body and is purified before being injected into the dermis. Its mechanism of action is fundamentally different from that of ECM-based products:
- Rejuran does not directly supplement collagen; instead, it activates fibroblasts through the polynucleotide, indirectly inducing the production of natural collagen.
- It enhances the skin’s balance of moisture and oil, improving skin instability caused by excessive sebum production or dryness.
- It provides deep hydration, increasing the skin’s water content at the cellular level.
Key Effects of Rejuran
- It reduces fine lines and improves the overall texture of the skin.
- It restores the skin’s moisture and oil balance.
- It lightens mild acne scars and uneven skin tone.
- It promotes overall skin repair and enhances the skin’s ability to renew itself.

Features and Limitations of Rejuran
Rejuran is a relatively viscous injectable, and patients usually experience a noticeable swelling and pain during administration. The time it takes for the papules at the injection site to subside is also slightly longer compared to ECM-based products. Additionally, the effects of Rejuran are gradual and cumulative; it generally takes 2 to 4 weeks to see significant changes, which is different from the more immediate improvements in texture observed after treatments with RE20 or CellREDM.

VI. Guidance on Choosing Based on Skin Type Issues
Situations Where RE20 Is the Right Choice
If you are experiencing any of the following issues, RE20 may be your top priority:
- Significantly coarser pores: RE20 has the strongest clinical data supporting its pore-minimizing effects
- Notable decrease in skin elasticity, feeling that the skin cannot be “lifted”
- Desiring to quickly see improvements in texture and lasting results
- Those familiar with ECM-based treatments or clinics with extensive experience administering RE20
Situations Where CellREDM Is the Right Choice
CellREDM should be considered in the following situations:
- Those who are more sensitive to pain and prefer a more comfortable treatment process
- For rough skin with low density, seeking an “inner-tightening” effect
- Desiring even distribution across the entire face for more refined ECM coverage
- Wishing for a quick recovery period after treatment to minimize disruption to daily life
Reasons for choosing Rejuran
Rejuran is particularly suitable for:
- Those with severely dehydrated skin and extreme imbalance in oil and moisture (dry or combination skin types)
- Those with mild acne scars or uneven skin tone, aiming for gradual overall skin improvement
- Younger individuals who prefer preventive maintenance rather than structural repair
- Those who have previously undergone ECM treatments and wish to alternate with different techniques
Doctors remind: Regardless of the treatment chosen, the most critical factor lies not in the product itself but in the skills and experience of the injector. Precise injection depth, even distribution, and personalized adjustments based on individual skin conditions are the key determinants of effectiveness. Be sure to seek consultation at a reputable medical aesthetics clinic and avoid opting for unqualified practitioners to save costs.
