What Is Quantum RF? Explaining the Effects and Downtime of Fractional RF Treatment for Sagging Skin

Quantum is the name of a cosmetic medical device that uses fractional RF, as well as the treatment performed with it. By delivering high-frequency energy to the skin, it acts on the tissues that cause sagging and produces a tightening effect.
In conventional treatments for sagging skin, the mainstream approach was to make an incision in the skin with a scalpel, as in facelift surgery, and physically lift it. By contrast, Quantum is positioned as a “non-surgical lift” that does not involve an incision, and is characterized by the ability to aim for improvement of sagging while limiting downtime.

Quantum uses a mechanism that emits fractional RF (radio frequency) in eight directions from its tip. RF (Radio Frequency) refers to high-frequency energy, which can deliver thermal energy to the deeper layers of the skin.
One cause of sagging is the loosening of the FSN (Fibrous Septae Network) beneath the skin. The FSN is fibrous tissue that connects the skin and fascia. As it stretches with age, the skin begins to droop.
Quantum delivers RF energy to the FSN, causing thermal contraction and producing a tightening effect. The emitted RF energy generates heat inside the skin, promoting collagen contraction and new collagen production. In addition to an immediate tightening effect after treatment, the collagen is rebuilt over the following several months, which is considered to potentially provide a sustained lifting effect.

Quantum can be used not only on the face but also on various areas of the body. Treatment of the face may be expected to improve the following concerns.

Many people also undergo treatment to achieve a slimmer-looking face. Treatment can be delivered to detailed areas, such as sagging around the eyes and forehead wrinkles, and another appealing feature is that areas of concern can be treated precisely.
For body treatment, Quantum can also be used for slimming purposes, such as improving sagging upper arms, abdominal laxity, and tightening the thighs. It may also be combined with Full body liposuction to tighten the skin after the procedure, and is chosen by people who want to improve their body contours.

The main effects expected from Quantum treatment are the following three:

Each is explained in detail below.

The primary purposes of Quantum are improving skin sagging and providing a lifting effect. Thermal contraction of the FSN lifts the skin and may create a more defined facial contour.
Many people feel a tightening sensation immediately after treatment, and the effects gradually become apparent over the following 1–3 months. Since new collagen production takes time, many people report that they feel the final effects 2–3 months after treatment.
The duration of the effects varies from person to person, but is generally considered to be approximately 1–2 years. Since age-related changes continue, regular maintenance treatment may need to be considered if you wish to maintain the effects.

Some people feel that their face looks slimmer as the facial contour becomes tighter. The treatment may be suitable for people who are concerned about fullness from the cheeks to the chin or who want a more defined facial outline.
It may also be expected to improve a double chin and create a more attractive profile. However, since it does not reduce fat, its face-slimming effect is limited for people with a large amount of fat. If volume caused by fat is the source of the concern, combining it with other treatments such as Fat-Dissolving Injection, BNLS, or Full body liposuction may be considered.

Since RF energy promotes collagen production, in addition to improving sagging, it may also improve the skin’s firmness and elasticity. Some people also experience secondary effects such as tighter-looking pores and a more refined skin texture. Some report that their skin looks more radiant and gives a more youthful impression.
However, if improving skin texture is the primary goal, other treatments, such as fractional laser treatment or Derma Pen, may be more suitable. Quantum is primarily a treatment for sagging skin, and it is appropriate to regard skin texture improvement as an accompanying effect.

When considering cosmetic medical treatment, the length of downtime and possible side effects are important factors in making a decision. We explain them in detail below. Use this information as a reference when deciding whether to undergo treatment.

Because Quantum does not involve an incision, its downtime is considerably shorter than that of facelift surgery. Redness and swelling may occur immediately after treatment, but in many cases they subside within several hours to several days. Bruising may also occur, and when it does, it generally disappears within approximately 1–2 weeks.
Some clinics allow makeup from the day of treatment, but depending on the degree of redness and swelling, it may be safer to wait until the following day or later. If you have an important event coming up, we recommend scheduling treatment with approximately one week of flexibility.

During Quantum treatment, local anesthesia or intravenous sedation is used, so you will feel little to no pain.
Anesthesia is generally used during Quantum treatment to reduce pain. Depending on the clinic, local anesthesia, intravenous sedation, or nitrous oxide sedation may be used, with the anesthesia method selected according to the treatment details and output settings. If you are concerned about pain, discussing the type of anesthesia and available options during your consultation may help you feel more reassured.
After treatment, a dull ache or discomfort similar to muscle soreness may continue for several days. In most cases, the pain is not severe enough to interfere with daily life, but if it concerns you, take the prescribed pain medication or consult the clinic.

Quantum is considered to be a relatively safe treatment, but this does not mean that side effects and risks are nonexistent. Possible side effects include redness, swelling, bruising, puffiness, and temporary numbness or changes in sensation. These usually improve over time.
Although rare, complications such as burns, hyperpigmentation, uneven skin texture, and nerve damage may also occur. Since the risks vary depending on the practitioner’s skill and experience, it is important to choose a clinic carefully.

Quantum treatment generally proceeds as follows.

Let’s take a closer look at each stage.

First, you will have a consultation and examination with a doctor. The doctor will assess the condition of your sagging skin, your skin type, and the results you hope to achieve, and determine whether Quantum is suitable for you. You will also receive an explanation of how it compares with other treatments, its expected effects and limitations, and its risks.
If you have any questions or concerns, it is important to ask them thoroughly at this stage. Once you decide to undergo treatment, you will schedule an appointment for the procedure. Some clinics perform the treatment on the same day as the consultation, while others schedule it for another day.

On the day of treatment, you will first wash your face to remove makeup and impurities. The doctor will then examine the treatment area and mark it as necessary. This is an important step for clearly determining which areas will be treated and to what extent.
Many clinics also take photographs before treatment, creating a record for comparing changes before and after the procedure.

Once the anesthesia has taken effect, treatment begins. The Quantum device is used to deliver RF energy to the target areas. Treatment time varies depending on the area and extent of treatment, but treatment of the entire face generally takes approximately 30 minutes to 1 hour.
You may feel warmth or a prickling sensation during treatment, but anesthesia reduces these sensations. If the pain is strong, the output can be adjusted, so do not hesitate to tell the practitioner.

You will receive instructions on precautions after treatment. In general, you will be advised to avoid strenuous exercise, alcohol, saunas, and prolonged bathing on the day of treatment.
Sun protection is also important, and using sunscreen is recommended. Since the skin may be sensitive for several days after treatment, it is better to avoid using highly irritating skincare products. If you notice any concerning symptoms, contact the clinic promptly.

There are various options for treating sagging skin. Let’s review the differences between Quantum and other treatments.

HIFU (HIFU: high-intensity focused ultrasound) is a popular non-surgical lifting treatment, like Quantum. HIFU concentrates ultrasound energy in the deeper layers of the skin, specifically the SMAS fascial layer, causing thermal coagulation to produce a lifting effect.
By contrast, Quantum uses RF (radiofrequency) and acts on the FSN (fibrous septae), which is the difference between the two. HIFU is generally considered capable of targeting deeper layers, but it also tends to be somewhat more painful.
Quantum primarily acts on relatively superficial layers, and some people report that it causes less pain. Which treatment is suitable depends on the condition of the sagging and the desired effects, so it is best to decide after consulting with a doctor.

A Thread lift involves inserting medical threads beneath the skin and physically lifting the tissue to improve the facial contour. It is characterized by the fact that it does not involve an incision and is generally considered to have relatively short downtime. However, a Thread lift is mainly intended to provide “lifting,” and its ability to broadly tighten the skin itself and deeper tissues is limited.

Quantum uses radiofrequency energy to target the skin, subcutaneous tissue, and fascial layer, tightening the skin, fat, and supporting tissues from within. Therefore, in terms of fundamental improvement of sagging and contour tightening, there are many cases in which Quantum makes its effects easier to perceive than a Thread lift alone. However, because Quantum is an energy-based treatment, temporary swelling, redness, and a sensation of heat may occur as downtime after treatment.

A Thread lift is suitable for those who want a lifting effect while minimizing downtime, whereas Quantum is suitable for those who want to tighten the skin and muscle tissue and improve the quality of sagging itself. Because their characteristics differ, combining the two is considered to potentially provide synergistic effects from both lifting and tightening.

In practice, some clinics propose treatment plans that aim for a more natural and longer-lasting lifting effect by first tightening the underlying tissue with Quantum and then combining it with a Thread lift. It is important to choose the most suitable treatment according to the condition of your sagging skin and your preferences.

Facelift surgery is a surgical procedure that improves sagging by making an incision in the skin and removing excess skin. It provides the most significant effect and has the longest duration, but general anesthesia is required, and downtime is also prolonged, lasting 2–4 weeks. There is also a risk of scarring, so the psychological barrier to surgery may be considered high.
Non-surgical treatments such as Quantum do not provide as dramatic a change as facelift surgery. However, non-surgical treatment may be suitable for people who are reluctant to undergo surgery, cannot take time for downtime, or have only mild sagging.

For those considering Quantum treatment, we have summarized important points to know in advance. Please use this information as a reference.

People who fall under any of the following categories may not be able to receive Quantum treatment.

People with underlying conditions such as diabetes or heart disease, as well as those taking blood-thinning medication, also need to exercise caution. Be sure to disclose this information during your consultation, and the doctor will determine whether treatment is appropriate.

In Japan, Quantum is classified as an unapproved medical device that has not received approval under the Pharmaceuticals and Medical Devices Act. Treatment using an unapproved device is provided as private medical care and is not covered by insurance. Being unapproved does not necessarily mean that the device is dangerous, but it is important to understand that, compared with approved devices, it has not undergone domestic review concerning its safety and efficacy.
Many clinics perform treatment based on overseas use and clinical data. However, when receiving treatment, make sure you receive an explanation about the device and make your decision only after you are satisfied with the information provided.

Quantum is a treatment attracting attention as a non-surgical option for sagging skin that uses fractional RF. Through the thermal contraction of the FSN and new collagen production, lifting and face-slimming effects may be expected. Its relatively short downtime and limited impact on daily life are appealing, but it does not provide as dramatic a change as facelift surgery.
It is important to choose a treatment that suits you by considering the degree of sagging, the effects you want, and the amount of downtime you can accept. When considering treatment, we recommend consulting with several clinics and making a decision after receiving a thorough explanation of the expected effects and risks.
