What is Water Light Injection (Vital Injector)?
Water Light Injection is a skin-quality treatment in which a drug selected to match your concerns is injected directly into the dermis, a relatively shallow layer of the skin. The effects vary widely depending on the drug selected. We choose the drug best suited to you according to your concerns and wishes.
In addition to the drug's effect, the Water Light Injection machine itself inserts fine needles, so through the body's own "wound healing" process it also has skin-regenerating and collagen-boosting effects.
Characteristics of Water Light Injection
You can choose your preferred drug
You can choose, according to your preference, from agents that are also popular in Korea—such as Juvelook (shown in the case photos above) and Rejuran.
A physician can examine you and recommend the drug best suited to you
Even if you feel "I'm not sure what to do...," a physician will examine you and suggest several of the drugs best suited to you.
Short treatment time
With whole-area injection by a physician, each spot must be injected one at a time, but Water Light Injection has nine needles and can inject nine points in a single shot, making the procedure quick.
Can work deep within the skin
Because active ingredients can be injected directly into the "dermis" deep within the skin, the drug takes effect from within the skin.
Reduces pain through a mechanism that injects while applying suction
Water Light Injection applies suction at the moment the needle is inserted. This suction mechanism has been shown to reduce pain compared with simply inserting the needle.
Effects of Water Light Injection
The effects obtained vary depending on the drug injected with Water Light Injection. Below is a list of effects commonly obtained with many of the drugs.
- Skin hydration
- Improved firmness and radiance
- Improvement of fine lines
- Improvement of enlarged pores and dark spots
- Improvement of dullness and brightening of tone
- Improvement of skin quality
- Improvement of acne and acne scars
List of Drugs for Water Light Injection at Smart Skin Clinic
We keep a wide variety of drugs on hand so that we can meet a broad range of concerns and wishes. You are welcome to tell us the drug you would like, and if you are unsure, we can propose the optimal treatment based on a skin-analysis device and a physician's examination.
Juvelook
A hugely popular formulation in Korea, approved by the U.S. FDA and Korea's KFDA. *The FDA and KFDA are the equivalents of Japan's Ministry of Health, Labour and Welfare.
In fact, it won the Korea Consumer Award for two consecutive years, in 2022 and 2023. In addition, more than 400,000 people in Korea have already received it. (As of December 2023.)
Its ingredients include non-cross-linked hyaluronic acid and poly-DL-lactic acid (PDLLA). After injection, they are slowly absorbed by the body over one to two years, during which they stimulate fibroblasts to naturally increase collagen and elastin, so a lasting effect can be expected.
If you would like to learn more about Juvelook, please see below.
Rejuran
Its ingredients include polydeoxynucleotide (PDRN) extracted from salmon DNA. Because it uses ingredients derived from salmon, it is sometimes called a "salmon injection."
Rejuran also contains an ingredient called astaxanthin, which has a strong antioxidant effect said to be roughly 1,000 times that of vitamin E.
Sunekos
Made in Italy and holding CE Mark Class IIIApproved as compliant with European safety standardsand, in Europe, it is an injectable that has been approved as a medical device.
Its main ingredients are non-cross-linked hyaluronic acid and six types of amino acids. The blend ratio of this hyaluronic acid and amino acids is an internationally patented special formulation. This ratio has been proven to be an efficient ratio for collagen and elastin production.
If you would like to learn more about Sunekos, please also see below.
Exosome
Smart Skin Clinic uses Exosomes with a purity of 99%.
JALUPRO (Classic)
It has been in use since 2005 and has a track record of more than 1 million cases. Because its production plant is in Milan, Italy, it is also called the "Milan injection."
Its main ingredients include low-molecular-weight non-cross-linked hyaluronic acid plus four types of amino acids.
If you would like to learn more about Jalupro, please also see below.
Background to the Development of Water Light Injection (Mechanical Injection)
Water Light Injection is a machine that came into use in Japan around the 2010s.
The background to its development was" to solve the 'challenges' of manual injection performed by physicians "It seems the manufacturer that developed it had this objective.
So, let us introduce what the challenges of "manual physician injection" are.
*Please note that this is not a challenge that applies to all physicians, as there are differences in their technical skill.
1. Difficult to maintain consistency
You can imagine that with manual injection it is difficult to keep the injection depth and dosage constant. As a result, it has been said that quality could vary from one facial area to another and from one treatment to the next.
2. Highly dependent on skill / individual practitioner
As for point (1), conversely, it is not a problem if the physician's skill is high. On the other hand, not all physicians are highly skilled, so there was a situation where the outcome depended on the skill of the individual physician.
3. Time efficiency
Manual treatment can be time-consuming, which created the challenge of making it difficult to treat many clients.
4. Loss of accuracy due to fatigue
With manual injection, concentration is required for depth and dosage, so examining and treating a variety of clients in a single day could lead to a loss of accuracy due to fatigue.
5. Higher price because only a physician can perform it
Even with a good injectable formulation, injection procedures could only be performed by a physician. Because there is a wide range of tasks that only a physician can do, having a physician perform the procedure makes the price higher.
Because of these five challenges, the "injection machine = Water Light Injection" was developed to solve them.
In other words, we hope you will understand a Water Light Injection as a machine with the performance to solve the problems described above.
Writing it this way might make it seem that "Water Light Injection is superior to manual physician injection," but that is not necessarily the case. Next, we will explain the good points and bad points (limitations) of each.
Which is better, Water Light Injection or manual physician injection?
From what we have said so far, you might come to perceive that "Water Light Injection is superior to manual physician injection" or that "Water Light Injection is an all-round upgrade over manual physician injection."
To state the conclusion first, the optimal, superior treatment method changes depending on your situation and objectives.
Each treatment method has its good points and bad points (limitations), and there is also unique value that only a physician's injection can provide.
We will explain the good points and bad points (limitations) from the client's point of view.
Good points about Water Light Injection
- Because differences in skill are less likely to arise, it is easier to receive treatment with peace of mind regardless of the clinic.
- You can receive the formulation you want at a lower price than with manual physician injection.
Bad points (limitations) of Water Light Injection
- Not 100% of the injectable formulation can be delivered into the skin, and a small percentage may leak out. With manual physician injection, essentially 100% can be injected. For that reason, it can be wasteful in the case of expensive injectable formulations.
- Because the injection depth and dosage cannot be finely customized, for a full-face treatment where concerns differ from area to area, it is not possible to inject at a depth and dosage optimized for each area.
Good points about manual physician injection
- The injection depth and dosage can be customized according to each client's skin condition, concerns, and wishes for each area.
- The injectable formulation can be delivered into the skin at nearly 100% with almost no leakage.
- Depending on the physician's proficiency, the procedure can sometimes be faster and less painful than Water Light Injection.
Bad points (limitations) of manual physician injection
- Skill differs from one physician to another. It is highly dependent on the individual practitioner.
- Because there are other tasks that only a physician can perform, the price is higher than for Water Light Injection.
Please review the good points and bad points (limitations) above and try to choose the method that best suits you.
Those who are not eligible for the treatment
Those who are pregnant or breastfeeding
Those with abnormal immune function or a history of it, and those undergoing immunosuppressive therapy
Those prone to keloid formation, hypertrophic scarring, or pigmentation disorders
Those with a bleeding tendency, or those taking non-steroidal anti-inflammatory drugs such as aspirin or anticoagulants such as warfarin
- Those who have excessive sunburn, eczema, dermatitis, severely inflamed acne, or scabs at the Water Light Injection site
Risks and Side Effects・Downtime
Risks, side effects, and downtime may mean roughly the same thing to you, so we will explain them together.
With Water Light Injection, the drug is injected using something like a stamp fitted with nine needles. As a result, reactions such as the following occur.
Redness, swelling (puffiness), and pain may occur at the injection site.
The above reactionsIn most cases it returns to normal within two to three days.
Here are two examples of the condition immediately after treatment. As you can see, even when the treatment is performed under the same conditions, individual differences arise depending on skin type and constitution.


Another point I always make sure to mention is the possibility of “bruising”. Since there are sometimes misunderstandings about this, I’d like to explain it carefully.
First, please take a look at the following.
Due to the nature of the treatment, bruising may—though not always—occur at the needle puncture site. If bruising does occur, it gradually fades over the course of one to two weeks.
As noted here, bruising occurs at a certain frequency (about 3–10%).
Bruising happens when the needle strikes a "blood vessel (a vein)" beneath the skin, causing a small tear so that blood leaks out and clots.
In other words, to prevent this, it would be enough "not to hit a blood vessel," but these blood vessels (veins) are very fine and run differently (are located differently) from person to person. For that reason, it cannot be prevented 100%.
At Smart Skin Clinic, we make every effort to reduce the risk of bruising as much as possible. We would appreciate your understanding of this point when you visit us.
Downtime
Redness and raised bumps may occur at the injection site, but in most cases they return to normal in about 24 hours.
Due to the nature of the treatment, subcutaneous bleeding may occur at the needle puncture site, though not always. If bruising occurs, it gradually fades over 10 to 14 days.
Details
| Treatment Time | About 30 to 40 minutes (not including counseling) |
| Recommended Number & Frequency of Treatments | Although it varies by drug, we recommend about three to four sessions at intervals of roughly two to four weeks. |
| Downtime | About 2 to 3 days |
| Treatment on the day of counseling | Available |
| Makeup | Possible from about 24 hours later |
| Skincare | Possible right after the treatment |
| Shower | Possible from the same day |
| Pain | A slight pricking sensation when the needle is inserted. |

For those worried that "cheap prices mean it's diluted or fake"
In conclusion, at Smart Skin Clinic we provideGenuine agents (such as Juvelook), at the proper concentration and via the proper administration methodWe provide it as follows.
However, we understand that some people may feel uneasy, thinking, "If it's too cheap, that's actually scary...," "Could it be watered down...?," or "Could they be using a counterfeit...?"
To ease these concerns, we will explain our clinic's approach and the characteristics of the drug Juvelook.
Example: Juvelook is a “powder” product
Unlike drugs such as Profhilo and Sunekos, Juvelook comes in a box as a "powder" rather than a liquid. (See the image below.)

Because it is a powder, the following points are essential.
- It must be mixed with saline solution to dissolve it (there is a proper reconstitution method specified by the Juvelook manufacturer).
- After dissolving, it must be "stirred" (mixed thoroughly). If it is not mixed thoroughly, the effect may be uneven, or the ingredients may become unevenly distributed, creating a risk of lumps.
"Stirring" is the key point
At our clinic, we use a genuine Juvelook (JUVELOOK) mixer to stir the formulation thoroughly, as shown below.
The reason for our prices is "waste reduction and greater efficiency."
The reason our clinic is able to keep prices low is not because “we’re diluting the contents” nor because “we’re using counterfeit products”.
It is because, guided by our management and operational philosophy of “Making aesthetic medicine more accessible and smarter,” we thoroughly eliminate waste and maximize operational efficiency.
We maintain rigorous quality control over all processes related to our formulations.
Why we can deliver both "high quality" and "some of the lowest prices in the nation"The reasons we can achieve this
In fact, more than 90% of aesthetic clinics carry too many unnecessary costs to offer their patients the best possible price.
Guided by this awareness of the problem, we created an aesthetic clinic completely unlike the conventional norm.
(1) Areas with low rent
(2) Cutting back on lavish interiors
(3) Cutting back on excess staffing
(4) Cutting back on excessive advertising spend
This is how we deliver something other clinics can't match: the "High-quality Water Light Injection offered at one of the lowest price levels in Japan" we're able to achieve.
Some patients are also concerned about whether a formulation is genuine, given the low price.
To ease such concerns,we open a brand-new formulation on the spot and show it to you,which gives our patients peace of mind.

Smart Skin Clinic consistently earns high ratings in reviews on Google, Hot Pepper, KireiPass, and more.

FAQ
- Is one session effective?
-
It is of course effective even with a single session. Depending on the drug, some are more effective when repeated in sets of three or four sessions.
- How is it different from ordinary hyaluronic acid injections?
-
Conventional hyaluronic acid injections created volume by "physically" placing hyaluronic acid beneath the skin. The non-cross-linked hyaluronic acid used in Water Light Injection penetrates almost like a lotion, stimulating the skin's fibroblasts and naturally producing collagen and so on, thereby creating volume.
- Can I wear makeup after the procedure?
-
Because tiny holes are left all over the skin, we recommend avoiding makeup for about 24 hours.
- Why is it called "Water Light Injection"?
-
The watery, glowing, beautiful skin of Korean actresses came to be described as "water-glow skin." Because this "injection" aims to achieve such "water-glow skin," it was named the "Water Light Injection."
