What Is Lizne: An Evolved Rejuran Generic
Lizne is one of the latest skin-regeneration skin booster formulations drawing attention in the field of aesthetic medicine. This product isa generic product developed following the patent expiration of the well-known Rejuranand is positioned as an evolved version of Rejuran—inheriting its excellent effects while improving on its shortcomings.
Origin of the name
The name "Lizne" carries a deeper meaning.
- LIZ: from "Leeds" (peak/prime), representing the time when your skin was at its most beautiful.
- NE: from "Rene" (rebirth), symbolizing skin regeneration and rejuvenation.
In other words, "Lizne" was named with the wish to be "reborn to youthful skin." The name concisely captures the product's purpose and effect.
Relationship with Rejuran
Lizne is a generic version of Rejuran, but it is not simply a copy.Building on Rejuran's excellent effects, it was developed as a safer and more effective product by incorporating the latest technology and research. In particular, it focuses on the pain and redness that had been drawbacks of Rejuran, greatly improving both.
Features of Lizne: 5 Points of Evolution from Rejuran
Lizne inherits Rejuran's strengths while evolving significantly in the following five ways.
(1) High-purity polynucleotides (PDRN)
While Lizne is primarily composed of polynucleotides (PN) extracted from the DNA of salmonid fish,its purity has been raised to as high as 99%.This higher purity simultaneously improves efficacy and reduces the risk of side effects.
(2) Significantly reduced pain
Lizne is"Pain-free Rejuran"so much so that the pain during injection is reduced to the point that it is also called this. This is thanks to the removal of impurities through high-purity PN extraction and refinement technology and the pH adjustment of the solution. Clinical trials have also confirmed significantly less pain compared with Rejuran.
(3) Reduced post-treatment redness
Lizne isRedness after treatment is also significantly reducedas well. Because it is reduced compared with Rejuran, this should be a welcome evolution for those who have been receiving Rejuran.
(4) Optimal pH adjustment
In Lizne, the pH of the solution is adjusted to the ideal level for the skin. This reduces irritation during injection, easing not only pain but also the burden on the skin after treatment.
(5) Suitability for a wide range of areas
Lizne can be used on a wide range of areas, including the entire face, neck, and décolleté. A key feature is that it can be used safely even on areas that were difficult to treat with conventional products, such as around the eyes and mouth.
Thanks to these advances, Lizne offers a more comfortable and effective treatment for patients. Reducing pain and redness lowers the hurdle to receiving treatment, making it easier for more people to receive it.
*In addition, these excellent features of Lizne have been carried over to its successor, "VITARAN" as well. Vitaran is manufactured by BR PHARM—the same company as Lizne—to the same quality standards, and it is an evolved version that also incorporates pure vitamins.
Main Benefits of Lizne: Firmer, More Radiant Skin and Overall Rejuvenation
Lizne improves skin quality, and in particularit has a strong "firmness and radiance" effect.
Lizne is also an injectable formulation based on polynucleotides (PN). PN has the following properties:
- Cell-activating effect
- Promotes tissue repair and regeneration
- anti-inflammatory action
- antioxidant action
Thanks to these properties of PN, Lizne is designed to support comprehensive skin rejuvenation, including improved firmness and radiance and better overall skin quality.
The main benefits of Lizne are as follows:
(1) Improved skin firmness and radiance
The high-purity PN in Lizne activates fibroblasts in the dermal layer and promotes the production of collagen and elastin. This helps improve the skin's firmness and elasticity, while enhancing how light reflects off the skin's surface, leading to more radiant skin.
(2) Improvement of wrinkles
Through PN's cell-activating effect, wrinkles such as fine lines and nasolabial folds may be improved. It is particularly effective for fine wrinkles around the eyes and mouth.
(3) Overall improvement of skin quality
Moisturizing effect: PN has strong water-retention properties and enhances the skin's ability to hold moisture.
Reduced skin problems: Its anti-inflammatory action helps improve acne scars and other scarring.
Pore tightening: As overall skin firmness improves, enlarged pores become less noticeable.
Improved skin tone: Its antioxidant action helps suppress melanin production, supporting brighter, clearer skin without dullness.
Common hyaluronic acid products (cross-linked) work by "filling in" the loss of bone and fat volume that comes with aging, helping to refine facial contours and improve wrinkles and nasolabial folds. The injected hyaluronic acid stays in the treatment area and produces a localized effect.
Lizne, on the other hand, spreads widely after injection and acts on the skin as a whole. In other words, rather than adding volume, it aims to deliver overall rejuvenation by improving the skin quality itself and activating cells.
How Long Lizne's Effects Last
Overseas clinical studies have reported that more than 90% of patients treated with high-purity PN formulations like Lizne felt the effects lasting even three months later. This suggests that Lizne promotes regeneration from deep within the skin, not merely superficial improvement.
In this way, Lizne is a treatment that improves the skin's firmness and radiance while offering comprehensive rejuvenation. In particular, it can aim for the kind of natural improvement in skin quality that conventional hyaluronic acid products could not achieve.
How Lizne Works
Lizne's effects come from the combined action of its main component, polynucleotides (PN). Specifically, three main mechanisms are at work:
(1) Activation of fibroblasts
PN directly stimulates and activates the fibroblasts in the dermal layer. Activated fibroblasts promote the production of collagen, elastin, and hyaluronic acid. These components play an important role in supporting the skin's structure and giving it firmness and elasticity. As a result, wrinkles may improve and sagging may be reduced.
(2) Angiogenesis (new blood vessel formation)
PN helps promote the formation of new blood vessels. New capillaries improve the supply of nutrients and oxygen to the skin. This activates the skin's metabolism, promoting the removal of old dead skin cells and the production of new cells. As a result, the skin gains healthier color and looks brighter and more vital.
(iii) Anti-inflammatory action
PN has a powerful anti-inflammatory action. Chronic inflammation is one of the factors that accelerate skin aging, and PN helps suppress it. It is also effective in improving inflammatory skin problems such as acne and redness. In addition, it helps protect the skin from inflammation caused by external stimuli such as UV rays.
Through the combined action of these mechanisms, Lizne delivers comprehensive improvement in skin quality. Particularly noteworthy is that these effects reach across a wide range, from the deeper layers of the skin to the surface.
Furthermore, the latest research suggests that polynucleotides (PN) may help promote DNA repair. Considering that the accumulation of DNA damage from UV rays and other factors contributes to skin aging, this is a welcome effect.
In this way, rather than making only superficial improvements, Lizne works comprehensively from the cellular level of the skin, delivering lasting, natural improvement in skin quality.

A Detailed Comparison of Lizne and Rejuran
Lizne was developed as a generic version of Rejuran, but it is not simply a copy—it is an evolved formulation. A comparison is shown below.
Component
- Rejuran: primarily composed of polynucleotides (PN).
- Lizne: also primarily composed of PN, but with a high purity of 99%.
Effect
- Rejuran: offers effects such as skin regeneration, wrinkle improvement, and enhanced firmness and elasticity.
- Lizne: essentially offers the same effects as Rejuran.
Pain
- Rejuran: known for relatively strong pain during injection.
- Lizne: pain is greatly reduced thanks to high-purity PN extraction and refinement technology and pH adjustment.
Downtime
- Rejuran: involves redness and swelling after treatment.
- Lizne: redness and swelling are reduced compared with Rejuran, and downtime is slightly shorter.
Duration
- Rejuran: the duration of effect varies from person to person but generally lasts about 3 to 6 months.
- Lizne: with its high-purity polynucleotides (PN), the effects last longer than with Rejuran.
Number of Treatments
- Rejuran: typically, 3 to 4 treatments spaced 2 to 4 weeks apart are recommended.
- Lizne: same as Rejuran.
Pricing
- Rejuran: relatively expensive, as it was the first polynucleotide (PN) product brought to market (and patented at that time).
- Lizne: as a generic product, it can often be offered at a lower price than Rejuran.
Clinical Track Record
- Rejuran: has a long track record of use, with a large body of accumulated clinical data.
- Lizne: a relatively new product, but clinical data have been accumulating. Fundamentally, it is a polynucleotide (PN) formulation similar to Rejuran, so Rejuran's data also apply.
In this way,Lizne is an evolved polynucleotide (PN) formulation that inherits Rejuran's strengths while improving in various ways, including reduced pain, reduced redness, and lower pricingis the result. In particular, the reduced "pain" that had been a problem with Rejuran should be a major benefit for those who want to receive Rejuran.
Which layer is it injected into?

Injectable preparations differ in both their ingredients and their purpose.
For this reason, the layer suited to each preparation"layer"and"amount"is very important for drawing out the effect correctly.
In the case of Lizne, the primary injection layer is the "superficial dermis."
The skin has a layered structure—from the surface: the epidermis, the dermis (superficial, middle, and deep layers), the subcutaneous fat layer, and the muscle layer—each playing a different role. The superficial dermis lies just beneath the epidermis and is the layer responsible for the skin's "visible texture," such as smoothness, firmness, and moisture.
The superficial dermis is the layer where Lizne's ingredients and intended effects are most effectively delivered, and this is the medical rationale behind our clinic's practice of injecting this formulation into that layer.
Recommended Number & Frequency of Treatments
3 to 4 times, spaced about 3 to 4 weeks apart. After that, maintenance once every six months to a year.
Downtime
This section explains the downtime period, symptoms, and recovery process for Water Light Injection.
Downtime Period
Downtime for Water Light Injection is about 2 to 3 days.
Downtime Symptoms
Downtime symptoms include redness, swelling, pain, edema, bruising, and temporary bumps at the injection site.
As for the raised bumps from the Water Light Injection solution, they resolve within 48 hours in most cases. If bruising occurs, it gradually fades over 10 to 14 days.
After 48 hours, it can generally be covered with makeup, but if you have important plans, please schedule accordingly.
Swelling and redness
With Water Light Injection, the needle is inserted while the skin is suctioned. The suction pressure and needle punctures may cause redness or swelling at the treatment site.
These symptoms subside in about 1 to 5 days, depending on the depth of injection.
Needle marks
The needle punctures may remain slightly red immediately after injection. This can be covered with makeup such as foundation.
These symptoms subside within a few days.
Bruising
If the needle damages a blood vessel running through the skin during injection, bruising may occur. Bruising is more likely in areas with thin skin, so extra care is needed around the eyes and neck, but it can generally be covered with makeup such as concealer.
These symptoms subside in a few days to about 10 days.
If you would like to see the detailed recovery process in photos, please read the following article.
Aftercare
For the first several days from the day of treatment, please keep the following points in mind. Proper aftercare is important to bring out the full effect of Lizne and maintain it over the long term. Appropriate daily skincare and healthy lifestyle habits also help sustain the results.
Keeping the skin clean:
- On the day of treatment, refrain from bathing and just rinse lightly in the shower. You may gently wash your face from the next day.
- Avoid high-temperature environments such as hot springs and saunas for 3 days after treatment.
UV protection:
- Avoid direct sunlight for one week after treatment, and be diligent about sunscreen when going out.
- Using sunscreen with strong UV protection is recommended.
Skincare:
- Refrain from using harsh cosmetics (retinol-containing products, peeling agents, etc.) for 3 days after treatment.
- Focus on skincare that emphasizes moisturizing.
Makeup:
- Makeup can be applied from the day after treatment, but be sure to apply it gently.
- Using products that are gentle on the skin is recommended.
Lifestyle:
- Avoid alcohol and strenuous exercise on the day of treatment.
- Try to get enough sleep and stay well hydrated.
Safety
Lizne is a formulation with a high level of safety, from the following perspectives.
Biocompatibility:
- Polynucleotides (PN), the main component of Lizne, have a structure similar to human DNA, making them highly biocompatible.
- As a result, the risk of allergic reactions and rejection is extremely low.
High purity:
- Lizne uses PN with a high purity of 99%.
- With fewer impurities, the risk of side effects is reduced.
pH adjustment:
- Because the pH of the solution is adjusted to the ideal level for the skin, there is less irritation.
Non-permanent:
- Because PN is gradually broken down within the body, any problems that may arise are temporary.
Large-scale overseas clinical trials have highly rated the safety of high-purity PN formulations like Lizne. One study reported zero serious side effects across more than 1,000 procedures.
However, the risks vary depending on your individual constitution and health condition. When considering treatment, it is important to always have a detailed consultation beforehand to confirm whether it is suitable for you.

Frequently Asked Questions (Q&A)
- Can I make a new reservation for Lizne?
-
Lizne is currently not accepting new reservations due to the discontinuation of the formulation's supply. We now offer the successor product produced by the same manufacturer (BR PHARM), "VITARAN." Please note that patients who have already begun (or are continuing) treatment with Lizne can still book Lizne treatments as long as stock is available.
- Is it okay to switch from Lizne to Vitaran?
-
Yes, there is no problem. Vitaran is manufactured by BR PHARM—the same company as Lizne—to the same quality standards, and it is listed under the same license-number designation on the Korean MFDS manufacturing license. The ingredient specifications are also nearly identical, with the addition of pure vitamins. Patients currently undergoing treatment with Lizne can transition smoothly.
- When can I start to feel the effects of Lizne?
-
Results vary from person to person, but many people feel improved firmness and elasticity immediately after treatment. The overall improvement in skin quality tends to appear gradually from about 2 to 3 weeks and often peaks over 2 to 3 months.
- How long do the effects of Lizne last?
-
The duration of effect varies from person to person but averages about 4 to 8 months.
- What is the difference between it and Rejuran?
-
Lizne is a generic version of Rejuran, but it uses more highly purified polynucleotides and has an adjusted pH, so it tends to cause less pain and less redness. It is also effective for a wider range of concerns.
- How much does it hurt?
-
Lizne causes so little pain that it is called "pain-free Rejuran." Many people report feeling only mild irritation. That said, the perception of pain varies from person to person.
- Is there a risk of side effects?
-
Lizne is a very safe formulation, but temporary side effects such as mild redness, swelling, and bruising may occur. Serious side effects are extremely rare.
- How many treatments should I have?
-
We recommend 3 to 4 treatments spaced 3 to 4 weeks apart.
- Can I receive it if I have a fish allergy?
-
Because Lizne uses salmon-derived DNA, those with an allergy to fish or fish roe cannot undergo the treatment.
