Quantum RF Disadvantages and Precautions | What You Should Know to Avoid Regret

Quantum RF is a treatment that uses the highest-end handpiece on the Ignite RF platform developed by InMode. A thin cannula (needle) is inserted beneath the skin, and radiofrequency (RF) energy is delivered in eight directions to promote collagen contraction and regeneration, tightening sagging from within.

A useful way to understand this treatment is to view it as positioned between “energy-based device treatments” and “surgery.” Device treatments such as HIFU and photofacials deliver energy from outside the skin. While this involves less physical intrusion, there is an upper limit to the results.

A facelift (incisional lift), on the other hand, is surgery in which the skin is directly incised and lifted. Although the effects are powerful, it places a greater physical and psychological burden on the patient. Quantum RF lies between the two in that it directly approaches the subcutaneous tissue without making an incision. Its essential feature is that it can act at depths unreachable by device treatments while avoiding the level of burden associated with surgery.

In recent years, it has been introduced at many clinics as a treatment that meets the need for “a substantial treatment for sagging without incisions.”

Quantum RF has several disadvantages and risks. Understanding them correctly before treatment can contribute to more satisfactory results. Information emphasizing the benefits is often easier to find, but receiving treatment without knowing its disadvantages is more likely to lead to regret. We therefore explain them frankly here.

Because Quantum RF delivers thermal energy directly beneath the skin, burns may occur depending on the energy settings and treatment technique. If the skin-surface temperature is not properly controlled, there is also a risk that inflammation, hyperpigmentation, or scarring may remain.

It is important to understand that this risk is influenced less by the design of the device itself than by the physician’s skills and experience. More careful energy control is particularly necessary around the face and in areas where the skin is thin.

Even when the same device is used, physicians may differ in their decisions regarding the treatment pattern and output. Receiving treatment from a physician with extensive experience and experience managing complications is an important first step in reducing risk. At our clinic, physicians continuously monitor the temperature sensors built into Quantum RF to help avoid the risk of burns. Please feel free to consult us if you have any concerns.

Because this treatment directly acts on the subcutaneous tissue, unevenness or tightness may develop on the skin’s surface if the energy is delivered unevenly or excessively. In particular, when performed together with Full body liposuction, changes in the tissue occur in combination, making the final result more difficult to predict.

It is also important to remember that unevenness or tightness may become more noticeable after swelling subsides and the recovery period has ended, rather than immediately after treatment. Once it develops, improvement may take time, and corrective treatment may sometimes be necessary. During the pre-treatment consultation, it is important to review photographs of previous cases and choose a physician who will speak frankly about the post-treatment course.

At LIVELY CLINIC, we have an aftercare system in place. If you have any concerns after treatment or notice even a slight unusual change, we provide examinations free of charge. Please do not hesitate to contact us.

The final result varies from person to person depending on the original condition of the skin, age, amount of fat, and ability to regenerate collagen. When people say that the effect felt weak, this is often due to setting expectations too high or judging the results during the recovery period.

Because tissue changes continue for three to six months after treatment, the final result cannot be accurately assessed until after that time. It is difficult to dramatically improve severe sagging with a single treatment, and multiple treatments may be necessary. Choosing a physician who explains the limitations of the effects frankly during the consultation is essential to avoid feeling afterward that the result was not what you expected.

Although Quantum RF does not involve an incision, it still involves a certain degree of intrusion into the subcutaneous tissue. Contracture (a condition in which the muscles or skin around a joint harden and shorten, making it difficult to move the joint or limiting its range of motion) generally lasts around one to three months as a guideline for the recovery period. However, it may last longer depending on the intensity of the energy delivered and the treatment area. For people who cannot easily take extended time off because of work, household responsibilities, or childcare, the length of the recovery period can be a significant concern.

For a smooth recovery, you should allow plenty of time in your schedule around important events and follow post-treatment activity restrictions, such as avoiding strenuous exercise, prolonged bathing, and alcohol.

Because Quantum RF involves inserting needles beneath the skin, the use of anesthesia is required. Pain perception varies from person to person, so understanding what to expect in advance can help reduce anxiety.

Local anesthesia is generally used for the procedure. Anesthetic medication is injected into the treatment area to reduce pain during treatment. Some clinics may offer intravenous anesthesia (sleep anesthesia) for extensive procedures or for people who are particularly anxious about pain.

Some people experience slight pain from the anesthesia injection itself, but once the anesthesia takes effect, most people feel only slight pressure or warmth at the needle insertion site during treatment. The type of anesthesia used varies by clinic, so it is important to decide in consultation with the physician.

Once the anesthesia wears off, the treated area may feel warm, irritated, or dull and painful. In many cases, these sensations subside within a few days, but if severe pain persists, contact your physician immediately. Properly using the pain medication prescribed after treatment and keeping the treated area rested are important for promoting recovery.

Caution is necessary because overexerting yourself while swelling or bruising remains may delay recovery.

From a safety perspective, treatment is not recommended for people who fall into any of the following categories: those with a pacemaker or metal implants in the body; those who are pregnant or breastfeeding; those with an active infection or inflammation in the planned treatment area; those with a serious systemic illness; and those with a tendency to develop keloids.

In addition, if you have previously undergone a heat-based treatment such as HIFU or laser treatment in the same area, the physician must carefully assess the interval since treatment and the condition of your skin. Caution is advised with clinics that proceed without making these checks. Be sure to ask the physician during your consultation whether you are eligible for treatment.

Quantum RF is a relatively expensive treatment among cosmetic surgery procedures. For the entire face, the cost is in the 400,000–800,000 yen range, and it is not uncommon for the cost to exceed 1,000,000 yen when combined with Full body liposuction. The main reasons for the high cost are the introduction and maintenance costs of InMode’s highest-end device, as well as the physician’s technical and time costs required for safe and precise treatment.

The costs of detailed pre-treatment consultations and post-treatment follow-up are also reflected in the price. Choosing a clinic based solely on low cost may increase the risks associated with inadequate device maintenance or insufficient physician experience. It is important to make a comprehensive decision by assessing whether the clinic has an appropriate level of expertise, equipment, and aftercare.

At present, Quantum RF is an unapproved medical device that has not obtained approval under Japan’s Pharmaceuticals and Medical Devices Act. This does not necessarily mean that it is a “dangerous device.” Because obtaining approval under Japan’s Pharmaceuticals and Medical Devices Act requires considerable time and cost, devices that are highly regarded overseas may still have their approval in Japan delayed. InMode has obtained approval from the U.S. FDA and has accumulated clinical experience overseas.

However, the fact that it is an unapproved device is important information that patients should understand before treatment. If a side effect or complication occurs, there may be disadvantages compared with approved devices in terms of support systems and insurance coverage. Patients are expected to receive a sufficient written explanation, understand its contents, and then provide consent. Please feel free to ask about anything you are unsure of during your consultation.

Many of the risks associated with Quantum RF depend more on the physician’s skills, experience, and judgment than on the device itself. Conversely, this means that choosing a good physician can substantially reduce the risks. Please use the following points when selecting a clinic.

Quantum RF directly approaches the fatty layer beneath the skin. Without anatomical knowledge that enables the physician to accurately understand the paths of nerves, blood vessels, and lymphatic vessels, the risk of damaging important tissues during treatment increases.
We recommend confirming the following points:

Choosing a physician with extensive experience in the above areas contributes to safety. We recommend asking during the consultation how many procedures the physician has performed and which treatment areas they specialize in.

A definitive statement such as “This alone will definitely make you look younger” is a warning sign. Physicians who clearly explain individual differences in results, limitations, and risks are more deserving of trust. A physician who can say, “This treatment may not be suitable for your condition,” is also demonstrating that they prioritize the patient’s interests.

Whether actual case photographs can be viewed on the official website is an important factor in making a decision. Clinics that openly disclose photographs, including those taken during the recovery period, can be considered to have experience and confidence to support their results. Caution is advised when only before-and-after photographs are shown and the intermediate course cannot be seen.

It is essential to confirm in advance the clinic’s post-treatment follow-up procedures, its policy for responding to complications, and the approximate cost of corrective treatment. Clinics that are difficult to contact after treatment or that provide only vague explanations about additional costs should be avoided.

At LIVELY CLINIC, we believe that monitoring your progress after treatment is an important part of the treatment process.

If you have any concerns after treatment or notice even a slight unusual change, we provide examinations free of charge. Please feel free to contact us.

There is no need to hesitate and wonder, “Is it okay to ask about something this minor?” Supporting your healthy recovery and helping to resolve your concerns is also our responsibility. Please feel free to consult us about anything, no matter how small, via our official LINE account or by phone.

If you are concerned about the disadvantages of Quantum RF, comparing it with other treatments for sagging may also help you make your decision.

HIFU delivers ultrasound from outside the skin and does not require needles, making its short recovery period a key feature. Because it has little impact on daily life, it can be an accessible treatment option for busy people.

On the other hand, it is less likely to provide the same level of tightening as Quantum RF, and its ability to address severe sagging is limited. HIFU is a strong option for people with mild to moderate sagging who want to minimize the recovery period.

Thread lift involves inserting dissolvable threads beneath the skin to physically lift it, and its immediate lifting effect is often visibly apparent. However, risks such as the threads becoming visible or causing tightness have also been reported.

Because the mechanisms of action differ, this is not a matter of which treatment is superior. The choice depends on what kind of change you are seeking and how much recovery time you can accept.

LSSA (Elsa) is a treatment specialized for improving skin hardness, tightness, and unevenness after Full body liposuction.
It uses physical ultrasound to loosen the tissue, so it has a lower risk of burns than Quantum RF and is suitable for delicate tissue repair.

On the other hand, Quantum RF tends to provide stronger tightening for sagging itself. It is important to choose according to your goal: LSSA if you want to improve the appearance after Full body liposuction, and Quantum RF if you want to actively enhance the tightening effect.

We have compiled questions frequently asked by people considering treatment. Organizing your questions before the consultation can help you make more effective use of the limited time available.

The duration of the effects varies from person to person. However, because the treatment approaches the tissue from within, it is said to make tightening easier to feel as time passes and to maintain its effects for a relatively long time.
Because sagging progresses with age, many people consider undergoing another treatment once the effects begin to fade. It is important to understand before treatment that this is not a treatment whose effects last permanently after just one session.

Quantum RF can be performed on its own. However, in areas with a large amount of fat or significant skin laxity, the effects may be more limited than when it is combined with Full body liposuction. We recommend asking your physician directly during the consultation whether treatment on its own is suitable for your condition.

You need to rest on the day of treatment, and returning to daily activities from the following day is generally possible. However, noticeable swelling and bruising may last for approximately one to two weeks. If your work involves meeting people or you have important plans, schedule the treatment with plenty of time to spare. With treatment to the jawline or face, how you spend the recovery period may particularly affect the final result.

The disadvantages of Quantum RF include the risk of burns, unevenness, a lengthy recovery period, individual differences in results, and high costs. A fundamental characteristic of this treatment is that many of these risks can vary greatly depending on the physician’s skills and experience. Where you receive treatment and who performs it can affect the outcome. Understanding the disadvantages correctly and making a decision based on your condition and lifestyle is the best way to choose a treatment you can feel comfortable with.
