“After receiving 300 HIFU treatments, is it really possible to see the results on the jawline?” This is the question I’ve received the most private messages about on REDnote recently 💬 To be honest, when I had my first treatment, I didn’t feel anything at all – it was just a waste of money 💸 It wasn’t until my second treatment, when I changed the clinic and the treatment method, that I finally understood how to get the best results from 300 treatments ✨
Today, I have compiled all my two years of experience using Korean ultrasound treatments in one article. This includes information on the specific application methods, energy settings, potential price traps, as well as the differences I observed during actual consultations at the Lovae clinic in Gangnam and the Seoul I clinic in Cheongdam. 📋 After reading this, you should be able to determine whether this treatment is suitable for you. If you want to save time on researching, you can also directly add WeChat friend s-sourire. She has extensive knowledge about Korean cosmetic clinics and can help you find the right treatment plan for you 👍

🔬 What exactly is HIFU ultrasound, and what are the differences between it and Thermage?
The principle of HIFU is to use focused ultrasonic waves to target the subcutaneous fat layer and the SMAS fascia layer, causing the tissues to contract and tighten. The main difference between it and Thermage lies in…
- 🧬 Different depths: The deepest penetration of HIFU reaches 13 mm, allowing it to act directly on the fat layer; Thermage mainly targets the dermal layer at a depth of 2.4–4.3 mm.
- 🎯 Suitable for different areas: HIFU is suitable for fat-related issues such as the jawline and Double Chin; Thermage is ideal for overall skin tightening.
- ⚡ Different levels of pain: HIFU causes stinging sensations near the bones, while the soft tissue areas experience less pain; Thermage generates a continuous heat sensation.
- ⏳ Duration of effect: HIFU lasts approximately 1 to 2 years, while Thermage lasts around 1 year.
- 💨 Recovery period: HIFU has virtually no recovery period at all – you can resume your normal activities on the same day as the treatment; Thermage may cause redness to appear for 1–2 days.
If you, like me, belong to the category of people who have lost weight but still have some fat on their faces, HIFU ultrasound would be more suitable for you than Thermage 👌. However, if you have significant sagging in various areas of your face, Thermage offers a wider range of treatment effects. In fact, these two treatments do not conflict with each other; many South Korean women alternate between using HIFU and Thermage every year 💡.

😖 I’m troubled by my Double Chin: Even after losing 10 kilograms, it’s still there.
Let me start by describing my situation: I am 160 cm tall and have lost weight from 68 kg to 52 kg, but my Double Chin hasn’t changed at all 🤦♀️ Whenever I take a side-profile photo, it looks like I’ve gained another 10 kg. Even when I go to get my hair cut, the Designer always asks, “Do you tend to get puffiness easily?” That’s really annoying.
After completing a lot of research, I decided to go to Seoul to have HIFU treatment. My first choice was Lovae Dermatology in Gangnam – just walk 200 meters straight out of Exit 4 of Sinsa Station on the subway, turn left after passing Starbucks, and then enter the alley; the white building is very easy to spot 📍. The second time I went was to ID Hospital in Cheongdam – exit 1 of Chongneung Station, about a 3-minute walk from there.
Both companies use officially certified Umiro versions of the Hafe device, but the treatment methods are quite different – I’ll explain the details later. If you’re not sure which treatment approach is right for you, you can first add me on WeChat at s-sourire and consult with me. Just tell me your situation and budget, and I will help you find the most suitable clinic and treatment plan for you 😊
📍 Allocation of 300 injections at Lovae Clinic: Focused primarily on the chin line.
I received my first treatment of 300 injections at Lovae, and the director allocated the number of injections as follows:
- On both sides of the jawline: 120 hairs (60 hairs on each side, arranged in two rows)
- Double Chin area: 80 hairs
- On both sides of the cheeks: 60 hairs
- The transition area from the chin to the neck: 40 hairs
The energy level is set between 1.2 and 1.5 J; during the treatment, there is a noticeable discomfort near the jawline, but it’s still tolerable 😅 The redness on my face lasted for about 2 hours before subsiding. The director said that the effects would only become apparent after a month.
A month later, when I took a photo from the side, I could indeed see that my jawline had become more defined. My friends also asked, “Have you lost weight recently?” — But actually, my weight hadn’t changed at all 🎉 However, the results weren’t as significant as I had expected, because the 300 hairs were distributed all over my face, so the focus in the jawline area wasn’t strong enough.
🏆 Cheongdam ID Hospital recommends starting with a minimum of 400 treatments: a focused strategy.
Later, when I consulted at ID Hospital, the doctors suggested starting with 400 units. The distribution method was different: more units were allocated to the jawline (150 units), while the Apple Zone was completely left untouched 💡. Their approach was: “Using 300 units across the entire face is like sprinkling pepper everywhere; it’s better to focus the treatment on the areas that need it most.”
The doctor also specifically mentioned one important point: it’s not that the more hair implants, the better. Instead, the number of implants should be adjusted according to the thickness of your fat 🔑. In areas where the fat is thicker (such as the Double Chin), multiple implants should be placed; in areas where the fat is thinner (around the jawline), just a few implants are sufficient. Too many implants, on the other hand, may cause indentations ⚠️.
| Project | Lovae (300 strands) | ID Hospital (400 treatments) |
|---|---|---|
| Reference price | 800,000 to 1,000,000 Korean won | 1.2 to 1.5 million Korean won |
| The number of hairs along the jawline | 120 shots | 150 shots |
| The amount of hair on the Double Chin | 80 shots | 100 shots |
| Energy range | 1.2-1.5J | 1.0 – 1.8J (customizable) |
| Tactics and strategies | Scattered across the entire face | Focus on the areas with the most problems |
| pain sensation | medium | Upper-middle range |
📝 Record of my in-person consultation at Lovae Dermatology: The entire process from consultation to the completion of the treatment
Upon arriving at Lovae, the receptionist will first ask you to fill out a questionnaire and then take you for a photo shoot 📷. During the in-person consultation, the director pinched my jawline and said, “Your fat thickness is approximately 1.5 centimeters; Hafei is the perfect treatment for you – there’s no need for liposuction.”
He also specifically reminded me of several things:
- ❌ Do not go to saunas or hot yoga within one week after the treatment.
- 😐 In the first three days, there may be slight swelling on the face, which is a normal reaction.
- 📅 The best results will only become apparent after 1 to 3 months.
- 💧 After the treatment, drink plenty of water and avoid spicy foods on the same day.
During the treatment, I lay on my side, and the nurse would first apply a layer of gel. The director administered the injections one by one, asking, “Does it hurt here?” Every time an injection was given near the jawbone, there was indeed a slight stinging sensation, but it wasn’t unbearable 😣 The entire process took approximately 40 minutes.
I looked in the mirror right after the treatment, but I couldn’t see any difference at all. The director said, “Don’t worry, come back in a month to check again.” 🤷♀️ And indeed, it was only after a month that I noticed a clear improvement in my jawline when I took a side-profile photo. My friends also asked, “Have you lost weight recently?” — but actually, my weight hadn’t changed at all. Friends who are considering this treatment can add me on WeChat at s-sourire for a consultation first.

Comparative illustration of the cost-effectiveness of Hi-Frequency Ultrasound treatment packages
⚠️ Hafei Ultrasound Price Traps: These three areas are where you are most likely to encounter problems.
🚨 Key point one: A package of 300 treatments at an extremely low price
Some clinics offer bargain packages like “300 HIFU treatments for just 400,000 Korean won”, which seem very attractive. However, you need to be cautious—these treatments are usually done using older models of equipment (not the Ultimate version), or the energy output is extremely low (below 0.8J) 🙅♀️. In such cases, the treatment is essentially ineffective; you spend the money but get no results. For the genuine, officially certified Ultimate HIFU equipment, 300 treatments cost at least 800,000 Korean won.
🚨 Point 2: Selling ordinary sound waves as Haifu products
There are a vast number of HIFU devices available on the South Korea market, but not all of them are called Ultherapy 🤔 Some clinics use vague names such as “ultrasonic HIFU” or “focused ultrasonic therapy,” yet charge the same price as Ultherapy. To confirm whether a device is genuine, ask if it is an “Ultherapy original equipment certified device”; only those that can provide a certificate are authentic ✅
🚨 Point 3: Misreporting the number of hair transplants performed
Some clinics claim to use “300 injections” when, in fact, they include the number of injections at each individual site. For example, if one area is injected three times, that counts as 3 injections, but the actual coverage area hardly reaches 300 individual sites 📐. The proper thing to do is to clarify whether they are referring to the “total number of injections” or the “total number of sites”.
By avoiding these three pitfalls, you’ll basically prevent wasting money 💰. If you want to save trouble, you can also arrange everything directly through WeChat by contacting s-sourire. The clinics she collaborates with have all been personally inspected by her, so you don’t have to worry about running into any problems 👍.
💡 Which treatment combinations offer the best value when combined with Hi-Frequency Ultrasound?
- ✨ Hafei + Filler for the Double Chin: Ultrasound waves are used to tighten the facial contours, while Filler is used to increase the length of the double chin. The combination of these two treatments results in better outcomes than using either alone – it is ideal for cases involving both a retracted double chin and a Double Chin. These two procedures can be performed on the same day, with ultrasound treatment coming first followed by Filler injection.
- 😤 Hafei + Botulinum Toxin for Face Slimming: Ultrasound is used to treat fat, while botulinum toxin is used to target the Masseter. These two treatments do not interfere with each other and can be performed on the same day. For those with a larger Masseter, this combination yields the most noticeable results.
- 💉 HIFU + Rejuran PN: After HIFU, apply Rejuran PN to hydrate the skin, promote Collagen production, and ensure a more comfortable recovery period. It is recommended to wait one week before using Rejuran PN again.
- 🔥 Haifu + Thermage: Use them alternately, one year for Haifu and one year for Thermage. This approach covers both the fat layer and the dermis effectively. Those with sufficient budget may consider this option.
It is recommended to discuss your treatment plan with your consulting doctor, as not everyone is suitable for undergoing two procedures on the same day. You can add me on WeChat at s-sourire to get a consultation and find out which combination is right for you 💬
❓ FAQ on Common Issues Related to Hi-Frequency Ultrasound in the Medical Aesthetics Industry
Q: How often should Hafei ultrasound treatments be performed?
A: It is recommended to have the treatment once a year to once every one and a half years. Having it too frequently is actually not beneficial; the body needs time to recover and regenerate 🔄
Q: Can I fly immediately after the treatment?
A: Yes, Hafei ultrasound treatment does not leave any scars and therefore does not affect your ability to fly ✈️. However, it is recommended to drink plenty of water on the day of the treatment and avoid environments with high temperatures.
Q: What are the side effects of Hi-Frequency Ultrasound treatments?
A: The common side effects are mild redness and stinging sensations, which usually subside within 3 to 5 days. In very rare cases, some people may experience bruising or nerve discomfort, but these symptoms generally resolve within one or two weeks 🏥
Q: At what age is it suitable to undergo this procedure?
A: People over 25 years old can consider undergoing this procedure. For those with obvious sagging or a Double Chin, the results will be more noticeable after the age of 30.
Q: Which is better, Haifu or HIFU?
A: The principles of the two are similar, but the HIFU certification is more stringent and the equipment is more precise 🔬 HIFU devices are usually cheaper, but the quality of these devices varies greatly depending on the manufacturer. If your budget allows, it is recommended to choose HIFU.
✅ People suitable for receiving HIFU ultrasound treatment VS those who are not suitable
Suitable for ✅: People with normal weight but local fat accumulation on the face (Double Chin, blurred jawline), mild skin laxity, who wish to achieve non-invasive improvements.
Not suitable ❌: Severe sagging (considering thread lifting or facelift procedures); fat layer thickness exceeding 3 centimeters (liposuction should be performed first); pregnant women or individuals with a pacemaker.
In summary, Hafu ultrasound is indeed effective for the lower jaw line and Double Chin, but this is only possible if there are enough treatment sessions, the correct amount of energy is used, and the clinic is reputable 💪. Don’t be attracted by extremely low prices, and don’t assume that 300 treatments on the entire face are sufficient. Concentrate the treatments on the problem areas to achieve noticeable results. If you have any questions, feel free to add her on WeChat at s-sourire; she responds quite quickly 👋.
