Key Summary
If you are concerned about narrow areas such as the jawline or double chin, we recommend 300 shots, and if you are concerned about wide sagging from the cheeks to the jawline or the neck, we recommend 600 shots. When calculated using the manufacturer's default values, 300 shots are a little less than the layer that supports the sagging skin under the cheeks, jawline, and chin (350 shots), and 600 shots are close to filling the elastic layer in the skin (660 shots).
- If narrow areas are a concern, we recommend 300 shots.
- If you are concerned about wide sagging or neck, we recommend 600 shots.
- If you have less facial fat and saggy cheeks, decide which areas should be excluded before deciding the shot count.
In the reviews, there was no evidence to suggest that 600 shots hurt more. The expression “it was quite painful” was used in 27% of reviews of 300 shots and 23% of reviews of 600 shots. The median review time for treatment time was 20 minutes for 300 shots and 30 minutes for 600 shots, and swelling lasted from 10 days to 2 weeks in 1 in 4 patients. There is no comparative study showing that 600 shots are several times better than 300 shots.
Who may be better suited to 300 or 600 shots of Ultherapy?
If the problem area is narrow, compare 300 shots first, and if it is wide or you want to see elasticity, compare 600 shots first. The table below shows the number of shots calculated based on the manufacturer's default values by concern.
| My concerns | Option to compare first | Reason (manufacturer default) |
|---|---|---|
| Jaw line becomes blurred and double chin appears | 300 shots | 230 shots even if both layers of the jaw line and under the chin are filled |
| Sagging from the cheeks to the jaw line and loss of elasticity | 600 shots | 660 shots to fill two layers of the same area |
| I am also concerned about neck sagging and neck wrinkles | 600 shots | 150 shots added to the neck fascia layer only |
| Wanted on the forehead and around the eyes | 600 shots or eye area only product | 100 shots for the forehead, eye area, and under-eye elastic layer only |
| There is little facial fat and the cheeks look saggy | Choose excluded areas before the shot count | A design that avoids hollow-prone areas takes priority |
Who may be better suited to 300 shots?
People with blurred jaw lines or narrow areas of concern such as a double chin are the ones to compare first. Even if the jaw line and under the chin are filled with two layers of fascial layer and elastic layer as the manufacturer's default, it is 230 shots, so it falls within 300 shots.
- People like this: My cheeks are fine, but I'm worried about my jawline and under my chin. I have less facial fat, so I'm worried about cheek depressions.
- Basis: Manufacturer's default calculations and reviews. There were 132 reviews that mentioned sagging cheeks or cheek dents, but most of them were concerned or said they were “avoided through design.”
- Limitations: Just because 300 shots is a small amount does not mean it is safe. What is more important is where it is used.
- Check first: Ask if it is designed to avoid areas you do not want to reduce, such as the cheeks.
Who may be better suited to 600 shots?
This is a composition recommended first for those who have sagging or loss of elasticity from the cheeks to the jaw line and who want to have it done up to the neck. If you fill the two layers of the cheek, jaw line, and under the chin with the manufacturer's default values, it will take 660 shots, and the neck fascia layer will require an additional 150 shots.
- People like this: My cheeks are sagging, my jawline is collapsing, and I am also concerned about neck wrinkles and neck sagging.
- Basis: Manufacturer's default calculations and research. In a study where 600 to 700 shots were administered to the face or neck, 8 out of 10 people responded that sagging had decreased after a year.
- Limitations: Distributing shots across the entire lower face and neck (default 960 shots) will only fill about 60% of the default for each area. The treatment time is also 30 minutes on average, which is longer than the 20 minutes for 300 shots.
- What to check first: Listen to the explanation of how many shots are divided into which parts of the 600 shots.
What is the difference between Ultherapy 300 shots and 600 shots?
The range that can be filled and the treatment time are different, and the level of pain and swelling were similar in the reviews. The additional 300 shots can be used to treat another skin layer in the same area or to add a new area such as the neck.
| Comparison Items | 300 shots | 600 shots |
|---|---|---|
| Range filled with manufacturer defaults | Slightly less than the fascia layer on the cheeks, jawline, and under the chin (350 shots) | Close to 660 shots to fill the elastic layer of the same area |
| Concerns about what suits you | Narrow areas such as jawline and double chin | Wide sagging from cheeks to jawline, neck |
| Procedure time (median) | 20 minutes (50 items) | 30 minutes (18 items) |
| “It was quite painful” in the review | 27% (out of 542) | 23% (out of 189) |
| Mention of sedation in the review | 22% | 23% |
| Swelling mentioned in review | 20% | 21% |
| Mention of bruises in review | 7% | 7% |
| Public price (Gangnam, VAT included) | Median price approximately 1.37 million won (average approximately 1.29 million won), minimum approximately 760,000 won ~ maximum 1.65 million won | Median price: approximately 2.41 million won (average approximately 2.52 million won), minimum approximately 1.97 million won ~ maximum 3.3 million won |
We checked 2,355 reviews, and the number of shots was divided based on the number written in the body of the review. Please note that there are only 50 and 18 reviews that describe the treatment time.
How was the pain different in the reviews between Ultherapy 300 shots and 600 shots?
The pain expressions in the 300 shot and 600 shot reviews were similar, and We could not find any reviews that said the 600 shot was more painful. We confirmed 731 reviews that reported pain (542 for 300 shots, 189 for 600 shots).
| Pain expression | 300 Shot Review | 600 Shot Review |
|---|---|---|
| It was quite painful, painful | 27% | 23% |
| It was hot and stinging, but it was bearable | 36% | 33% |
| It almost didn't hurt | 37% | 44% |
- Anesthesia: Reviews that mentioned sedation were 22% of reviews for 300 shots and 23% of reviews for 600 shots. The number of reviews saying they received it without anesthesia was 2.4% for both shots, and the anesthesia method was similar for both shots.
- Painful areas: There were 6 reviews that said the bone area was painful, and 36 reviews that it was uncomfortable, tight, or heavy.
- No comparison in the same review: There was no article directly comparing the pain between 300 shots and 600 shots in the same review.
Because reviews are self-reported, these figures should be read as patterns in reported experiences rather than clinical incidence rates.
How long can swelling and bruising last after Ultherapy?
Swelling lasted from 10 days to 2 weeks in 1 in 4 people, and bruising was mentioned in only 7% of reviews. This is what the 69 reviews about swelling had with the duration written down.
| Until the swelling subsides | Review Rate |
|---|---|
| Within 2 days | 22% |
| 3 days | 12% |
| 4-5 days | 14% |
| About 1 week | 22% |
| 10 days to 2 weeks | 27% |
| 3 weeks or more | 3% |
- Percentage of mentions of swelling and bruising: Swelling and redness were the same in 20% of reviews and bruising in 7% of reviews, which was the same for 300 and 600 shots.
- Instant daily life: There were 78 reviews of 300 shots and 31 reviews of 600 shots (about 5.7%) that said it was possible to return to daily life without downtime.
- When making an appointment: 52% of reviews said that the swelling lasted for more than a week, so it is safe to receive treatment 2 weeks in advance for important appointments.
Are 300 shots safer if I have little facial fat?
Fewer shots do not automatically make you safer. If your cheeks are saggy or you have little facial fat, you need to decide which area to remove rather than the number of shots.
There were 132 reviews (70 reviews of 300 shots, 40 reviews of 600 shots) that mentioned cheek hollowing or indentation. Most people were worried about it, avoided it because of the design, or said it didn't happen, and We could not find any reviews that said cheek hollowing occurred. There were a few comments saying that it looked like facial fat had disappeared, but it was just accepted as an effect.
The instructions warn that tilting the tip, incorrectly spacing treatment lines, or creating air bubbles in the gel can cause burns and scars. Cases reported after marketing include burns, blisters, fat loss, and sensory abnormalities, and it is difficult to determine how often they occur based on reports alone, the user manual said. In the review, there were two posts about numbness around the lips, and one of them said that they were told that Ultherapy was not used in areas where nerves pass, such as the corners of the mouth.
What should I do if more shots are recommended during the consultation?
Select the number of shots by the area of concern, and if recommended, ask which area to take more shots. Of the 103 reviews that mentioned adding shots, 43 said they added shots or received additional recommendations, and 22 said there was no additional recommendation.
- Recommended review: At first, 600 shots were recommended, but there was a review that said they took 400 shots because they were worried about pain, and another review that said they tried to take 400 shots but increased it to 600 shots.
- Review that was not recommended: I heard that 300 shots were less effective, but since it was my first time here, there was a review that said to start with 300 shots.
- Standard: The benefit of increasing the number of shots comes from filling the same area closely and in multiple layers, so the first priority is whether the increased shots are used on the area of concern.
What does 1 shot mean in Ultherapy?
The 1 shot in the price tag refers to the treatment tip passing one line over the skin, creating several small hot spots. In the user manual example, there are 17 hot spots in a 2.5cm line. 600 shots doesn't mean you shoot harder, it means you draw twice as many lines like this.
What is the difference between 1.5mm, 3.0mm, and 4.5mm tips?
The depth into the skin where heat collects varies. Ultherapy P Prime is a medical device approved as a 'focused ultrasound stimulation system' item in Korea, and the required layer is selected from three depths by changing the tip.
| Tip | Target layer | To put it simply |
|---|---|---|
| 4.5mm | Fascial layer (SMAS) | Membrane that covers facial muscles and supports sagging skin |
| 3.0mm | deep dermis | Elastic layer deep inside the skin |
| 1.5mm | shallow dermis | Elastic layer close to the skin surface |
The location of each tissue layer varies from person to person. In the 2024 trial, 9 of the 22 people identified by ultrasound screens had a thin muscle layer in the neck (the platysma muscle) at a depth of 3.0 mm instead of 4.5 mm. This is why the 2019 expert guidelines recommend determining the floor and the number of shots per layer using the ultrasound screen.
How much of the face can be filled with 300 and 600 shots?
300 shots can fill small areas, and 600 shots can fill the entire lower face or neck. Ultherapy fills in layers by changing the tip, with the 4.5mm tip targeting the fascial layer that supports sagging skin, and the 3.0mm tip targeting the elastic layer in the skin above. The equipment includes a default number of shots for each part on these two layers.
Add these values up to see how far you reach for each number of shots.
| Treatment configuration (manufacturer default) | Shots Required | 300 shots | 600 shots |
|---|---|---|---|
| Fascial layer and elastic layer on the jawline and under the chin | 230 shots | fill | After filling, 370 shots remain |
| Fascial layer of the jawline, under the chin, and neck | 260 shots | fill | After filling, 340 shots remain |
| Fascial layer on the cheeks, jawline, and under the chin | 350 shots | 50 shots short | fill |
| Fascial layer of the cheeks, jawline, under the chin, and neck | 500 shots | not enough | fill |
| Fascial and elastic layers on the cheeks, jawline, and under the chin | 660 shots | not enough | 60 shots short |
| Fascial and elastic layers of the cheeks, jawline, under the chin, and neck | 960 shots | not enough | not enough |
“Insufficient” means that the basic requirements are not met, but it does not mean that the procedure cannot be performed. The medical staff reduces or increases the number of shots for each area to suit the product, and where and how much the shots are reduced becomes the content of the procedure.
What changes did people who received Ultherapy feel?
In most studies, 8 to 9 out of 10 people reported improvement.
| Treatment range and number of shots | Changes felt by people |
|---|---|
| Lower face and neck, average 238 shots | After 90 days, 90% of people and 80% of medical staff evaluated that they had improved |
| Lower face and chin, fascia layer and elastic layer | After 90 days, 58% had improved cheek and chin sagging and jawline contour |
| Full face or neck, 600~700 shots | After 180 days, everyone evaluated their condition as improving, and after one year, sagging was reduced by 79%, wrinkles were reduced by 58%, and skin texture was improved by 47% |
| Comprehensive study of 42 studies (2024) | 89% of medical staff and 84% of people assessed their condition as improving, and 93% of them were satisfied with their face and neck |
Changes don't appear right away. According to expert consensus, new collagen is produced over about 10 weeks after the procedure, and the tissue is reorganized and tightening continues for up to a year. There are also reports that the improvement in the lower face and neck was maintained until one or two years later. It should also be taken into account that the comprehensive analysis of 42 studies was conducted with research funds from the manufacturer.
When treating the entire face and neck, the agreed upon amount is 800 to 1,200 shots. However, the guidance says not to treat this number as a universal answer, but to adjust it according to the size of the face, degree of sagging, fat distribution, and ultrasound screen.
Is the effect greater with 600 shots and how long will it last?
There is a study that shows that if you fill the same area more closely and in more layers, the lifting response may increase. However, there is no study comparing that 600 shots are several times better than 300 shots.
In a 2017 study, shots and energy were increased and three layers were applied to only one side of the wrinkles (marionette wrinkles) next to the corner of the mouth on one person's face. That side rose more and had better elasticity than the other side, both half a year later and a year later, but it hurt more. Since it is a preliminary study, it does not have much weight as evidence.
The expert consensus also follows the same direction. The results were better when the fascia layer and the elastic layer were filled together, and it was concluded that the tighter the shot for each layer, the better. It was also seen that if the shot was concentrated on only one layer, hot spots overlapped, which could lead to side effects.
So the effectiveness of 600 shots depends on where you use it. If you spread it across the entire lower face and neck (default value: 960 shots), each area will only fill in about 60% of the default value, and if you collect it in two layers on problem areas such as the cheeks and jawline, you get closer to the benefits seen in the study.
How long it lasts depends on your age rather than the number of shots. The 2021 agreement generally considers the interval between re-receipts to be 12 to 18 months, and recommends adjusting it to 24 months for those aged 30 to 45 and 12 months for those aged 50 or older. It is also explained that the older you are, the more frequently you may need to have it to maintain your results.
What do I need to know before receiving Ultherapy?
If there are any wounds, severe acne, internal electronic devices such as a pacemaker, or metal implants in the treatment area, the treatment will not be performed according to the instructions. If any of the following applies, you must inform us first before deciding on the number of shots.
| Category | If applicable |
|---|---|
| No treatment | Wounds at the treatment area, severe acne or cystic acne, internal electronic devices such as a pacemaker or defibrillator, metal implants at the treatment area |
| Avoid direct treatment over these areas | Fillers, implants, keloids |
| Areas to avoid | Thyroid gland and airways, large blood vessels and nerves, eyes and eyelids, inside the bones around the eyes |
| Effectiveness and safety not evaluated | Pregnancy and lactation, children, taking anticoagulants, bleeding disorders, skin diseases that slow wound healing, herpes, autoimmune diseases, diabetes, epilepsy, facial paralysis (Bell's palsy) |
What are some common misconceptions about Ultherapy?
The saying that “Prime is applied up to 8mm” is not true. 8mm is the depth that can be seen on the screen, and the depths that send heat are 1.5mm, 3.0mm, and 4.5mm.
The saying “the more it hurts, the better” has weak evidence. There is an opinion that it may hurt more if it hits a layer with many nerves, but the researchers themselves stated that this is an untested hypothesis.
What should I ask during a consultation?
Rather than the number of shots, you need to ask where and on what layer the shots are used. The same 300 shots are treated differently depending on whether they are used in one fascial layer or divided into two layers in a narrow area.
| What to check | Questions to Ask |
|---|---|
| Scope of treatment | Where does the face start from where does it end? Does it go into the neck too? |
| Distribution by layer | How many shots do you use for the fascial layer (4.5mm) and elastic layer (3.0mm)? |
| Distribution by part | Where do you use the most shots? |
| anesthesia | Is it sedation or numbing cream? Is the cost included? |
| Ultrasound screen | Do I choose tips by looking at my skin layer on the screen? |
| Genuine Tips | Do you show the original tip when opened and give an authenticity sticker? |
| Treatment history | Do you decide which areas to avoid based on filler, thread lifting, and surgery history? |
| Actual practitioner | Does the doctor I consult perform the procedure themselves? |
You can check whether the product is genuine on the list of hospitals and clinics participating in genuine product verification on the manufacturer's official website. However, since there are hundreds of hospitals listed across the country, differences between hospitals must be addressed by asking the questions above.
What is the basis for comparing the prices of Ultherapy 300 shots and 600 shots?
Even if the number of shots is the same, the actual price and range will vary depending on whether VAT, anesthesia, and throat are included.
| Comparison criteria | What to check |
|---|---|
| equipment | Ultherapy or Ultherapy Prime |
| range | Includes cheeks, jawline, under the chin, and neck |
| Total cost | Whether VAT, anesthesia, sedation, and follow-up care are included |
| Pricing Terms | First visit price, limited time, day of the week conditions |
| medical staff | Names and qualifications of consulting doctors and actual practitioners |
The prices in the previous comparison table are the prices of individual products (8 for 300 shots, 4 for 600 shots) released by Gangnam clinics on September 29, 2026, including VAT. Event prices are mixed and change frequently depending on the time of year. Looking at the four places that offered the two products together under the same conditions, 600 shots were 1.8 to 2 times the price of 300 shots, and the price per shot was the same or slightly lower for 600 shots. Still, The first question is whether the increased shots are used for my problem area. The amount and conditions for each clinic are organized with the source and confirmation date in the recommendation guide.
How DermaFocus compares clinics offering Ultherapy
The recommendation guide applies the same four criteria to all clinics.
| Comparison Items | Verification criteria |
|---|---|
| Treatment information | Equipment model, ultrasound screen confirmation, product authentication, post-procedure information disclosure |
| medical staff | Specialist qualifications and actual practitioners confirmed by official sources |
| cost | Confirmation date, VAT, price conditions, whether or not to include items |
| Reviews | Repeated mention of sources, writing time, consultation and explanation for each platform |
The number of reviews and specialist qualifications are not used as scores to guarantee treatment results. The role of a recommendation guide is to display confirmed facts side by side using the same standards.
How this article was checked
The DermaFocus editorial team directly read and organized the manufacturer's data, original papers, and actual reviews, and did not receive any medical supervision.
- Manufacturer's data: We checked the basic number of shots per area, unit of shots, warnings and adverse reactions in the original Ultherapy System user manual, and the treatment depth and approved items were checked in Mertz Aesthetics Korea's product information.
- Research: 2 expert consensus statements, 1 clinical trial, 1 comparative study on both sides of one face, 1 comprehensive analysis of 42 studies, and 1 narrative review listed in PubMed were read in full text or abstract. The results of individual studies cited in the consensus statement were confirmed in the text and tables of the consensus statement, and the manufacturer's research funding and the author's history of consulting with the manufacturer were listed in the source list.
- Calculation: The range by number of shots is the value added by the default value in the user manual based on both faces, and is not an individual prescription. One shot in the clinic price list was calculated based on one treatment line counting the equipment.
- Reviews: A total of 2,355 reviews, including 1,927 Gangnam Unni treatment reviews and 428 Babitalk reviews, were found in the search results for “Ultherapy 300 shots” and “Ultherapy 600 shots” on September 30, 2026. We reviewed the information regarding pain, swelling, bruising, and procedure time, and did not transfer the original review text, author, or clinic name. Because reviews are self-reported, the results may overrepresent satisfied users, and the number of shots was divided based on the number written in the text. The number of cases may vary by a few, and there may be cases where the same article is posted on both platforms.
- Price: We confirmed the official websites of 16 Gangnam clinics, Gangnam Unni, and Babitalk public prices on September 29, 2026. Excluding products that bundle other procedures and prices for the first visit, the median and average were calculated based on the lowest single product price that anyone can receive at each clinic, including VAT, and the name of the clinic was not included.
- Limitations: We could not find any studies that directly compared 300 shots and 600 shots under the same conditions, and there were no pain records comparing the two shot numbers in the same article.
Frequently Asked Questions
What is the difference between 300 and 600 shots of Ultherapy?
300 shots may cover a smaller area, while 600 shots may cover a broader area of the lower face. As the manufacturer's default value, 300 shots is slightly less than the amount (350 shots) that fills the fascial layer of the cheeks, jaw line, and under the chin, and 600 shots is close to the amount that fills the elastic layer of the same area (660 shots).
Who is Ultherapy 300 Shots and 600 Shots suitable for?
If you are concerned about narrow areas, we recommend 300 shots, and if you are concerned about wide sagging or neck areas, we recommend 600 shots. The two layers under the chin and chin are 230 shots, so it falls within 300 shots, and to fill the two layers up to the cheeks, 660 shots are needed.
Are 600 shots of Ultherapy twice as effective as 300 shots?
There is no such thing as double. However, there is a study that shows that filling the same area more densely and in multiple layers results in a higher rise, so there is an advantage when the increased shots are collected on the problem area.
Does 600 shots of Ultherapy hurt more than 300 shots?
In the review, pain expression was similar for both shot numbers. The reviews that said “it was quite painful” were 27% for the 300 shots and 23% for the 600 shots, and 22% and 23% of the reviews mentioned sedation, respectively. We found no evidence that 600 shots hurt more.
How long does Ultherapy swelling last?
Of the 69 reviews that wrote about the swelling period, 22% said it was within 2 days, 26% said it was 3 to 5 days, 22% said it was about a week or so, 27% said it was 10 days to 2 weeks, and 3% said it was more than 3 weeks. One in four people went as far as two weeks, so it is safe to receive important appointments two weeks in advance.
How much does 300 shots of Ultherapy cost?
The median price of individual products (including VAT) disclosed by eight Gangnam clinics was approximately 1.37 million won, with a minimum of approximately 760,000 won and a maximum of 1.65 million won. The median price for 600 shots is approximately 2.41 million won at 4 clinics, and event prices are mixed and change depending on the time of year.
How long does Ultherapy last and when does it take effect?
New collagen develops over about 10 weeks after the procedure, and changes continue for up to a year. The time to receive it again is usually one to one and a half years later, and the older you are, the more frequently it is recommended.
Is receiving two 300 shots the same as one 600 shot?
There is no basis to believe they are the same. This survey did not find any studies comparing the method of receiving 300 shots in two doses and the method of receiving 600 shots at once. If you plan to take it in installments every few weeks, talk about the reasons for doing so in your consultation.
Ultherapy 300 shots vs. 600 shots, how do you choose?
If you have a narrow jawline or double chin, we recommend 300 shots. If you are concerned about wide sagging from the cheeks to the jawline, or want to extend the neck, we recommend 600 shots. Once the number of shots has been decided, the next step is distribution, and if the consultation does not explain the number of shots for each area and layer, you cannot compare prices alone. In the review, the degree of pain between the two shots was similar, so check the anesthesia and pain control method in advance rather than the number of shots.
