A Thorough Comparison of Juvgen and Hyaluronic Acid Injection: Which Should You Choose?

To understand the characteristics of both treatments, let us first look at their basic mechanisms and features. Understanding the differences will make it easier to determine which treatment best matches your goals.

Juvgen (JUVGEN) is an autologous dermal regeneration treatment developed in South Korea. It refers to a procedure in which carbon dioxide gas and hyaluronic acid are injected alternately into the dermal layer using an ultra-fine needle and a dedicated device.

Because the treatment is performed from inside the skin rather than on its surface, the risk of side effects is reduced, and it has attracted attention as a highly safe treatment. Another highly regarded feature is that, unlike laser treatment, it does not require repeated sessions. For more information about Juvgen, please also refer here.

The effects of Juvgen are elicited through three types of stimulation: physical, chemical, and biological.

The process begins with the alternate injection of 0.001 cc each of carbon dioxide gas and hyaluronic acid to activate fibroblasts. The injected carbon dioxide gas reacts with water in the skin tissue to produce carbonic acid, promoting vasodilation. This delivers abundant oxygen and nutrients to the dermal layer and improves the cellular metabolism necessary for collagen production.

The activated fibroblasts produce new collagen and elastin, and this newly formed collagen fiber tissue pushes up the dermal layer from within. As a result, wrinkles and depressions can be improved.

The greatest feature of Juvgen is that it promotes the regeneration of the patient’s own tissue. Once formed, collagen tissue becomes established as the patient’s own tissue, so it can basically be maintained semi-permanently. In addition, unlike Hyaluronic Acid Injection, it does not require regular additional treatment, and there is a possibility of experiencing effects over the long term.

The effects gradually appear over 2 to 3 months after treatment, with the final result reached in 3 to 6 months. Although effects can be achieved with a single treatment, 1 to 3 sessions are recommended depending on the severity of the symptoms.

Hyaluronic Acid Injection is one of the most widely used treatments in aesthetic medicine. Hyaluronic acid is a substance that naturally exists in the body and has an excellent ability to retain water. It is effective for superficial volume enhancement and is characterized by its immediate effects. On the other hand, it is important to note that the desired effects may not be achieved in terms of duration or deep depressions.

With Hyaluronic Acid Injection, the product itself functions as a physical filler. The injected hyaluronic acid directly lifts depressed areas of the skin, making wrinkles and grooves less noticeable immediately.

There are various types of products, which also differ in firmness and particle size. A softer product may be used for shallow wrinkles, while a firmer product may be used for deep grooves or areas requiring volume. The appropriate product may be selected according to the treatment area and symptoms. Many products, such as the Juvederm series, are approved by Japan’s Ministry of Health, Labour and Welfare, which is another feature associated with high safety.

The greatest advantage of Hyaluronic Acid Injection is its immediate effect. You can feel the effects immediately after treatment and see a visible change right away. Another appealing feature is the relatively short downtime and limited impact on daily life.

However, hyaluronic acid is gradually absorbed by the body over time. Although this varies depending on the product and injection site, effects generally diminish after approximately 6 months to 2 years, making ongoing maintenance necessary. In addition, even if you are dissatisfied with the result, it can be reversed with a dissolving agent, providing reassurance.

Although both treatments share the goal of improving wrinkles and depressions, they differ significantly in many respects. Specifically, there are the following five differences.

Here, we take a detailed look at the five important differences that can help you make your decision.

The greatest difference is the duration of effects. With Juvgen, the newly generated collagen tissue becomes established as the patient’s own tissue, so effects can basically be expected to last semi-permanently. Because long-term improvement may be achieved with a single treatment, it may be possible to reduce the frequency of clinic visits and maintenance costs.

Hyaluronic Acid Injection is absorbed by the body over approximately 6 months to 2 years, depending on the product. The Juvederm series, which is approved by Japan’s Ministry of Health, Labour and Welfare, has been reported to last 18 to 24 months; even so, regular additional injections are necessary.

Although results vary from person to person, Juvgen may be preferable if you are seeking longer-lasting effects.

There is also a clear difference between the two treatments in terms of immediate effects. With Hyaluronic Acid Injection, you can feel the effects immediately after treatment. Because volume is physically replenished, depressions improve soon after injection, making it possible to see a visible change immediately.

By contrast, Juvgen takes time for its effects to appear. Changes gradually emerge over 2 to 3 months, and the result approaches completion at around 6 months. Juvgen may provide some immediate effect in certain cases, but basically does not act as quickly as hyaluronic acid. There are individual differences, and because it is a treatment that promotes the production of your own collagen, tissue regeneration requires a certain amount of time.

If you want immediate results, choose Hyaluronic Acid Injection; if gradual improvement is acceptable even without an immediate effect, Juvgen may be the better choice.

There are also differences in the indications. Hyaluronic Acid Injection can address a wide range of concerns, from shallow to moderately deep wrinkles. It can be applied to various areas, including nasolabial folds, marionette lines, and forehead wrinkles. It is excellent for superficial volume enhancement and is suitable when you want to improve your appearance immediately.

Juvgen is particularly effective for deep wrinkles and severe depressions. One of its major features is that it can address deep nasolabial folds, crater-like acne scars, and other scars that were difficult to improve with conventional hyaluronic acid. Fundamental regeneration from the dermal layer may enable improvement from deeper within the skin.

The two treatments also differ in terms of safety and risks, so caution is necessary. With Hyaluronic Acid Injection, there is a rare risk of an allergic reaction or impaired blood flow due to vascular occlusion. If the product is accidentally injected into a blood vessel, it may cause serious complications such as skin necrosis or blindness. However, it is reassuring that when treatment is performed by a physician with appropriate skills, any problems that arise can be addressed with a dissolving agent (hyaluronidase).

Because Juvgen also uses an extremely small amount of hyaluronic acid, the risk of impaired blood flow cannot theoretically be said to be completely zero. The risk is considered lower than with standard Hyaluronic Acid Injection because the product is injected in small amounts, but it cannot be completely eliminated. In addition, because the treatment involves regeneration of the patient’s own tissue, it is difficult to dissolve collagen once it has formed.

The number of treatments and total cost also need to be considered.

Hyaluronic Acid Injection produces an immediate effect with one treatment, but regular additional injections are necessary to maintain the results. Because clinic visits continue at a rate of once or twice a year, costs accumulate over the long term.

With Juvgen, 1 to 3 sessions are recommended depending on the severity of the symptoms. Although the cost per treatment is relatively high, long-term effects may be expected, so the total cost may be reduced over time. However, natural age-related changes cannot be avoided, and some people wish to undergo additional treatment for maintenance purposes several years later.

For easier visual understanding, we have summarized the key differences between the two treatments in a table. Use this table to understand the characteristics of each treatment and choose the one that is right for you.

As shown in this comparison table, each treatment has distinct characteristics. It is important to consider factors such as whether you want an immediate effect or a long-term effect, and the depth of the symptoms you wish to improve.

Juvgen is suitable for those seeking fundamental improvement in skin quality, while Hyaluronic Acid Injection is suitable for those who want to see an immediate change. Combining the two treatments may also make it possible to take advantage of the strengths of each. Through a consultation with a physician, develop a treatment plan suited to your individual symptoms and preferences.

To choose the treatment that is right for you, it is important to clarify the symptoms you wish to improve and the results you hope to achieve. We explain the options using specific examples.

Hyaluronic Acid Injection may be suitable for people who:

The greatest feature of hyaluronic acid is its immediate effect, and the treatment is not particularly difficult to undergo. For this reason, it may also be recommended for people receiving aesthetic medical treatment for the first time. It is also suitable for improving mild wrinkles and depressions.

On the other hand, Juvgen may be suitable for people who:

Compared with hyaluronic acid, which may provide temporary effects, Juvgen is a treatment intended to fundamentally improve skin quality. Although it takes time for the effects to appear, choose Juvgen if you are seeking long-term effects or a natural-looking result.

In actual clinical practice, an approach combining both treatments may also be used. For example, Juvgen may be used for deep depressions, while Hyaluronic Acid Injection may be used for shallow areas or areas where an immediate effect is needed.

The reason for combining them is that taking advantage of the strengths of each treatment may make it possible to achieve a more satisfactory result. Combination treatment offers the benefit of pursuing fundamental improvement with Juvgen while experiencing an immediate visible change with hyaluronic acid.

The specific treatment plan is determined through consultation with a physician, taking into account the individual’s symptoms, preferences, and budget. Please feel free to discuss your options.

Whichever treatment you choose, confirming details in advance is essential for achieving a safe and satisfactory result. In particular, whether the treatment is successful depends greatly on the physician’s skill and experience.

Juvgen is a relatively new treatment, making treatment by a physician with the appropriate skills and knowledge essential. Confirm whether the physician has undergone training in South Korea, where the treatment was developed, and whether they have sufficient case experience.

Hyaluronic Acid Injection also requires advanced skills for selecting the product and adjusting the injection depth and volume. It is important to choose a physician with extensive knowledge of vascular anatomy who can respond appropriately to complications should they occur.

During the consultation before treatment, it is important to receive a frank explanation of the expected effects and limitations. Do not have excessive expectations; instead, understand the realistic potential for improvement before deciding to undergo treatment. Ask for a detailed explanation of the risks and side effects, fully understand the possible risks—including rare complications—and undergo treatment only after you are satisfied with the information.

Both Juvgen and Hyaluronic Acid Injection are treatments that can effectively improve wrinkles and depressions, but they differ significantly in their mechanisms of action, duration, and suitable indications. Hyaluronic Acid Injection is suitable for those seeking an immediate effect and who do not find regular maintenance burdensome. Juvgen is recommended for those seeking long-term effects and fundamental improvement in skin quality.

The most important thing is to choose a treatment that suits your symptoms, preferences, and lifestyle. Receive a thorough consultation at a trusted clinic and develop the most suitable treatment plan in consultation with your physician.
