🔊 South Korea’s HEV Dermatology HIFU: Is this equipment reliable?

Environmental Overview of HEV Dermatology

When it comes to HIFU (High-Intensity Focused Ultrasound), it is undoubtedly the most popular treatment in South Korea’s aesthetic medicine market. However, despite both treatments being called HIFU, the results can vary vastly – some patients feel that their faces have become smaller after the procedure, while others report experiencing “no noticeable effect at all”. The key to these differences often lies not in the equipment itself, but in the person performing the treatment.

The Sinsa branch of HEV CLINIC in South Korea has introduced the Korean version of the HIFU device, the 10trip model. This device is renowned in the South Korean market for its stable energy output and advanced probe design. However, what truly sets this clinic’s HIFU program apart is not the device itself, but rather the doctor who operates it.

According to the hospital’s records, one of the directors of the Sinsa branch of South Korea’s HEV Dermatology holds the “operation training qualification” for the HIFU Second Generation device. What does this qualification mean? It means that this director is not only capable of performing HIFU treatments on patients but also has the authority to train other physicians on the correct usage of this technology – in fact, there are only about 10 physicians in South Korea who hold this qualification.

👨‍⚕️ Why is the qualifications of HIFU operators more important than the equipment itself?

Environmental Overview of HEV Dermatology

The principle of HIFU is to use focused ultrasonic waves to generate heat in the deeper layers of the skin, thereby stimulating the contraction and regeneration of Collagen and achieving a Lifting effect. Although the principle seems simple, there are numerous variables involved in its actual application:

  • Control of energy intensity: Different skin thicknesses and different areas (Forehead, cheeks, jawline) require varying levels of energy intensity. Applying too much energy to areas with thinner bones can cause pain and side effects.
  • Selection of probes: Probes with different depths of 4.5mm, 3.0mm, and 1.5mm should be carefully chosen based on the customer’s skin condition and desired results.
  • Control of the duration of exposure: The length of time spent at each point determines the total amount of energy transferred. If the time is too short, insufficient energy will be delivered, resulting in little effect; if the time is too long, it may cause burns.
  • Design of the injection route: Experienced doctors will design the most optimal injection route based on the patient’s facial structure to prevent issues such as an “uneven distribution of the effect” or an “unattractive facial appearance”.

For such technical details, ordinary practitioners may only need to complete basic training before starting to work. However, true experts are those who are able to find the optimal balance among a client’s facial structure, age, and skin condition. The director of South Korea’s HEV Dermatology is precisely one such expert.

Environmental Overview of HEV Dermatology

The appearance of results after HIFU treatment follows a rather unique time trajectory; it’s not as simple as “getting V-shaped cheeks immediately after the procedure”.

  • 1–2 weeks after the procedure: In the initial stages, there may be mild swelling and tenderness, and some clients may feel that their face feels a bit “tight.” The changes at this stage are not very noticeable.
  • 1–3 months after the procedure: This is the peak period for Collagen regeneration. During this time, you will notice that the contours of your face gradually become clearer, and the jawline begins to tighten. This stage is truly the most rewarding part of the process.
  • 3 to 6 months after the procedure: The effects continue to improve, reaching their optimal state. The specific duration varies from person to person.
  • 6 to 12 months after the procedure: The effects begin to diminish gradually, but a certain degree of improvement is usually still maintained.
  • After 12 months: Most customers need to receive another treatment to maintain the best results.

If proper care is taken (such as adequate sun protection, avoiding excessive weight loss, and maintaining a healthy lifestyle), the effects can last longer. It is important to note that the effectiveness of HIFU is closely related to the amount of energy used, the number of treatments administered, and the treatment area. Packages with excessively low prices often mean that the number of treatments has been reduced, resulting in significantly diminished effectiveness.

😣 A genuine account of the pain experienced during HIFU treatment at a Dermatology clinic in South Korea: Is it really that painful?

Environmental Overview of HEV Dermatology

The pain associated with HIFU is a concern for many people. What is the actual level of pain when undergoing HIFU treatment at HEV Dermatology in South Korea?

According to feedback from patients who have undergone the treatment, the pain level during HIFU sessions at the Sinsa branch of South Korea’s HEV Dermatology is considered “tolerable”. The main reasons for this are as follows:

  • The HIFU treatment offered by this clinic includes the use of a pre-operative anesthetic ointment, which is applied for approximately 30 minutes and can significantly reduce discomfort at the skin surface.
  • The dean, who possesses the qualifications for instructional guidance in medical aesthetics, is able to control the intensity of the treatment more precisely. In areas where the bones are more prominent, the energy level is appropriately reduced to minimize any discomfort.
  • The Korean-made 10trip HIFU device used in this hospital has seen improvements in pain control compared to earlier versions.

The areas where the pain is most intense are usually along the jawline (where the bones protrude) and near the temples. When injections are administered in these regions, there is a noticeable sensation of soreness and mild stinging. However, this discomfort is temporary and will subside shortly after the procedure is completed.

In summary, the pain associated with the use of HIFU at South Korea’s HEV Dermatology can be considered relatively mild compared to other similar treatments. Of course, individual experiences may vary, so girls who are particularly sensitive to pain are advised to discuss this in advance with the clinic director.

📋 Precautions after HIFU treatment at South Korea’s HEV Dermatology clinic

Environmental Overview of HEV Dermatology

Post-treatment care after HIFU is of utmost importance, as it directly affects the outcome of the treatment and the duration of its effects. The following are the key precautions that the director of South Korea’s HEV Dermatology Institute particularly emphasizes:

  1. Within 24 hours after the procedure: Avoid washing your face with hot water, and do not go to places with high temperatures (saunas, steam baths, hot yoga).
  2. Within 1 week after the procedure: Avoid using skincare products containing acids such as retinol, fruit acids, or salicylic acid, and also refrain from exfoliating your skin.
  3. Within 2 weeks after the procedure: Avoid excessive facial massage and refrain from any other high-intensity treatment using electronic devices.
  4. Sun protection: It is essential to strictly avoid exposure to the sun within 1 month after the procedure. Use sunscreen with an SPF of 50+ and reapply it regularly.
  5. Moisturization: Strengthen moisturizing care to promote the regeneration of Collagen.
  6. Avoid excessive weight loss: Within 1 to 3 months after the procedure, refrain from drastic weight loss, as rapid weight loss can affect the durability of the results.
  7. Avoid smoking and excessive alcohol consumption: These habits can accelerate the loss of Collagen and shorten the duration of the effects.

❓ Frequently Asked Questions

Environmental Overview of HEV Dermatology

Q: How many HIFU treatments are required for one session at a Dermatology clinic in South Korea?

A: The standard HIFU treatment for the entire face usually involves 200 to 400 treatments. The specific number of treatments required will be determined by the director of the clinic, based on the patient’s facial structure and desired results. At the Sinsa branch of South Korea’s HEV Dermatology, the director will conduct a personalized assessment during the initial consultation to ensure that the number of treatments and the energy level used achieve the best possible results.

Q: What is the difference between HIFU and Thermage?

A: The principles of the two treatments are different. HIFU acts on the SMAS layer by focusing ultrasonic waves to generate heat energy, focusing primarily on Lifting; Thermage (radiofrequency) targets the dermis layer, promoting Collagen regeneration and tightening the skin. Depending on an individual’s specific skin concerns, the clinic director will recommend the more suitable treatment option.

Q: How long does it take to see the results after HIFU treatment?

A: The initial results begin to appear 2 to 4 weeks after the procedure, while the optimal effects are usually seen 2 to 3 months after the surgery. The duration of these effects varies from person to person, but generally ranges between 12 and 18 months.

Q: How many times can HIFU be used in a year?

A: It is recommended to wait at least 12 months between each HIFU treatment, as too frequent sessions may cause damage to the skin.

Q: Why are there only 10 physicians in South Korea who possess the qualifications to teach HIFU operation?

A: This certification requires verification by the manufacturer, and the application requirements are quite stringent. These include the duration of clinical experience, the number and quality of cases treated, as well as the level of expertise in new technologies. Obtaining this certification signifies that the physician has met the highest technical standards in the field of HIFU.
