What Is Hiro Wave? A Complete Guide, from How It Differs from Fillers to How Long It Lasts
💉 We’ve organized the mechanism and selection tips for biostimulators in an easy-to-understand way
🌸 What Is HiroWave?
HiroWave is a biostimulator treatment featuring a “dual HA structure” that combines high-molecular-weight and low-molecular-weight hyaluronic acid.
Unlike standard fillers, it is designed to provide both immediate volume enhancement and the stimulation of collagen production.
It occupies a position that is somewhat different from both fillers and collagen boosters based on PLA or PDO.
Let’s take a step-by-step look at its structure and features.
It occupies an intermediate position, aiming to promote collagen synthesis while creating volume.
🔬 How the Dual HA Structure Works
HiroWave contains a combination of high-molecular-weight and low-molecular-weight hyaluronic acid.
.High-molecular-weight HA remains in the skin to create volume, while low-molecular-weight HA is designed to penetrate the tissues with the aim of promoting collagen and fat cell proliferation.
In other words, it is designed to provide both “immediate improvement” and “gradual enhancement” in a single treatment.
✅ Structural Differences from Conventional Fillers
Conventional fillers maintain their shape by stabilizing HA with a cross-linking agent called BDDE. Hiro Wave has a lower degree of cross-linking,and is said to have intermediate properties, aiming to promote collagen production while creating a natural-looking volume. It is a formulation that places greater emphasis on nurturing the tissue rather than creating a defined shape.
⚖️ Comparison with Collagen Boosters (PLA, PDO, and CaHA-based Products)
Many people are also curious about how Hiro Wave differs from conventional collagen-stimulating products such as Sculptra and UltraCol.
According to manufacturer materials and some clinical reports, Hiro Wave is said to have a faster onset of results and a lower tendency to cause nodules (lumps) compared with these products. However, results vary depending on the individual and the treatment area.
Because the HA particles are fine, it is thought that the risk of vascular occlusion may be reduced. In addition, in the unlikely event of a problem, another unique feature not found with other biostimulators is that removal can be considered using hyaluronidase (a hyaluronic acid-dissolving agent).
For those who “cannot wait for the results to appear” or “feel anxious about the final outcome,” this reversibility may provide some reassurance.
📍 Treatment Areas: Suitable and Less Suitable Areas
Hiro Wave is particularly well suited for areas where “depressions can be filled in naturally.”
It is considered suitable for areas where a “plumper appearance” is desired rather than finely sculpted contours, such as the midface (the front of the cheeks and the anterior cheekbone area), nasolabial folds, and hollow cheeks.
Conversely, conventional fillers may be more suitable for areas that require finely detailed shaping, such as the forehead, nose, and lips.
The typical amount used per treatment area is approximately 2 cc, but this varies depending on the area and its condition.
⏳ Duration of Effects and Recommended Frequency
The effects of a single treatment generally last for approximately 6–9 months.
When three treatments are received at three-month intervals, some cases have reported effects lasting up to approximately 18 months, although results vary by individual. However, this may vary depending on your constitution and the treatment area.
Since the collagen production-promoting effects are expected to build up with multiple treatments, many people consider treatment plans involving several sessions.
※ Results vary by individual. The above figures are for reference only and do not guarantee results.
💉 Treatment Day and Expected Downtime
Since a cannula (a tube with a rounded tip) is used during the procedure, many people reportedly feel little to no pain. Results vary by individual.
If there is no bruising or significant swelling, it may be possible to return to your normal routine on the day of the treatment.
✅ Post-Treatment Precautions (Guideline)
It is generally recommended to avoid alcohol, saunas, and strenuous exercise for approximately one week. The extent of bruising and swelling varies by individual. If concerning symptoms persist, consult the clinic where you received the treatment.
💰 Estimated Pricing (For Reference)
The following are general guidelines for Korean clinics. Prices vary depending on the clinic and treatment plan.
| Volume | Price (in KRW, excluding tax) |
|---|---|
| 2 cc | 600,000 KRW |
| 4 cc | 1,000,000 KRW |
| 6 cc | 1,400,000 KRW |
※ Prices are listed in Korean won. The equivalent amount in Japanese yen will fluctuate depending on the exchange rate. Please confirm the exact price with the clinic during your consultation. An additional discount may be available for a three-session treatment plan.
🏥 3 Points to Check When Choosing a Clinic
The outcome of a treatment depends not only on the product used but also greatly on the quality of the clinic.
Checking the following three points in advance can help you make an informed decision.
✅ What to Confirm During Your Consultation
① Whether the doctor provides the consultation directly
② Whether the doctor works with multiple products, such as fillers (BDDE-crosslinked), Sculptra (PLLA), Juvelook (CaHA), and PDO-based collagen boosters, and selects the appropriate one according to the patient's treatment area and goals
③ Whether the clinic provides before-and-after photo comparisons and has a well-established post-treatment follow-up system
Clinics that meet all three of these criteria can be considered reliable options for comprehensive volume treatment consultations, not limited to HiroWave.
✨ Summary
Things to Confirm Before Considering HiroWave
☑ Identify the areas where you want to naturally improve hollowness, such as the cheeks or nasolabial folds
☑ Tell your doctor that you are looking for both immediate results and stimulation of collagen production
☑ Discuss whether a single session or a multiple-session plan is right for you based on your goals
☑ Adjust your schedule in advance to accommodate lifestyle restrictions for one week after the procedure (alcohol consumption, saunas, and exercise)
☑ Confirm with the clinic whether you can have a direct consultation with a doctor who handles multiple products and ask about the post-procedure follow-up system
☑ Keep in mind that, in the unlikely event that you are dissatisfied with the result, dissolution with hyaluronidase may be considered
❓ Frequently Asked Questions
Q. How do you decide between HiroWave and regular fillers?
Regular fillers may be suitable for areas where you want to create precise definition, such as the nose and lips. HiroWave may be suitable when the goal is a “natural plumpness,” such as for hollow cheeks or nasolabial folds. Which option is right for you should be determined through a medical examination and consultation with a doctor. Consulting a doctor who handles multiple products is important.
Q. Can I return to work immediately after the procedure?
If there is no bruising or significant swelling, you may be able to return to your normal daily activities and work on the day of the procedure. However, the degree of swelling and bruising varies from person to person, so it is recommended that you consult with the clinic in advance before scheduling the procedure around important events or commitments.
Q. Can I notice an effect after just one treatment?
A single treatment is generally expected to last approximately 6–9 months. However, because the collagen-stimulating effect is believed to build up over multiple treatments, many people consider a multiple-treatment plan when seeking longer-term changes. Individual results may vary.
Q. What happens if I am dissatisfied with the result?
Because HiroWave is hyaluronic acid-based, removal with hyaluronidase (a dissolving agent) may be considered. This option is not available with PLA- or CaHA-based biostimulators, so it may be an advantage for those who prioritize reversibility. Please consult your doctor for details.
Q. What is the difference between Sculptra and Juvelook?
Sculptra (PLLA) and Juvelook share the goal of stimulating collagen production, but their effects may take time to appear. HiroWave is reported to offer immediate results and tend to have a relatively lower risk of nodules. The product best suited to you depends on your goals, individual characteristics, and treatment area, so consulting a doctor who handles multiple products can be helpful.
