A lifting device's "shot count" measures a different unit depending on the technology, so the same number from two devices can't be compared on price alone. Our Seocho director explains how depth, energy and pass count decide what a shot count actually means before any quote is given.
A device's "shot" is not a fixed unit. Ultrasound counts a line of tiny thermal points, radiofrequency counts a pulse over a wider area, and some machines drop the word entirely in favor of kilojoules, so the same number from two different devices can describe two different amounts of energy reaching two different depths. At our Seocho location, we diagnose where and how deep the sagging sits before we ever discuss a device, a depth, an energy setting, or a count.
I'm Kyung-soo Kim, director at UH CELL Seocho. I graduated from Seoul National University College of Medicine and hold medical licenses in both Korea and Japan. Our Seocho location is inside UH FLAT The Seocho. One of the most common questions I hear in consultation is some version of "how many shots, and how much." It's a fair question. The shot count is the only number a patient has to compare with. What I want to explain here is why I don't answer with a number first, and what I check before I do.
One "Shot" Doesn't Mean One Thing
A shot is simply the unit a device uses to describe one release of energy, but that release looks different depending on the technology.
High-intensity focused ultrasound devices concentrate sound waves into a single point, creating a tiny coagulation point, then string these points together in a line. Published research usually counts this unit as a "line," not a shot. A facial-laxity study registered with ClinicalTrials.gov (NCT06449911) treated one side of the lower face and the area under the chin with 300 lines plus 10,200 dots in the same protocol, so even a single study splits its count across two different units.
Radiofrequency devices work differently again. Monopolar radiofrequency heats a broader area wherever the tip makes contact, so there's no basis for treating one radiofrequency pulse as equivalent to one ultrasound line. Some microwave-based devices, such as Ondamed, are described in kilojoules of energy rather than shots at all. Our own Seocho KakaoTalk channel has described a body Ondamed session as "80KJ," not as a shot count.
Put a device's "300 shots" next to another device's "300 shots" and the two numbers describe different things. Even a single device's own shot-count pricing changes depending on which area and depth those shots are delivered to, which is exactly why we walk through area and depth before quoting a count.
Depth Decides What the Same Number Actually Reaches
Before a number, ultrasound lifting requires a depth decision. A pan-Asian expert consensus published in The Journal of Clinical and Aesthetic Dermatology describes micro-focused ultrasound with visualization (MFU-V) as delivering low energy at three set depths, 1.5mm, 3.0mm, and 4.5mm, reaching from the superficial skin down to the SMAS fascia layer.
Sofwave, which we introduced at our Seocho location this past May, was described by Star Daily News as a device that delivers energy to a dermal depth of roughly 1.5mm. A "200 shot" session at 4.5mm in the fascia and a "200 shot" session at 1.5mm in the dermis are aimed at different structures. The deeper layer generally targets the tissue that supports sagging; the shallower layer targets skin texture and fine lines.
A 2020 prospective study indexed in PubMed reached a similar conclusion: a single session of MFU-V was reported as safe and effective for facial laxity, on the condition that an appropriate number of energy lines reached the correct tissue layer. I treat that condition as the actual point of a shot-count conversation. The number only means something once it's matched to the layer it was delivered to.
What Published Line Counts Actually Look Like
The counts below come from published research protocols, not from any individual treatment plan; an actual count is set after diagnosis.

Population and area
Depths used
Line count
Study published in Clinical, Cosmetic and Investigational Dermatology
Upper neck, cheeks, brow area, lateral canthal area, infraorbital area
4.5mm and 3.0mm, two layers
At least 800 lines
ClinicalTrials.gov NCT06449911 (20 patients)
One side of the face: two-thirds of the lower face, submental area
4.5mm, 3.0mm
300 lines + 10,200 dots
The wider the area and the more layers involved, the larger the number gets. Different studies land on different totals because they cover different areas and layers, not because one protocol is stronger than another. A shot count is closer to an output of the plan than an input to it.
Radiofrequency Changed How It Divides Energy
The history of monopolar radiofrequency is a useful illustration of how a shot count should be read. A 2005 paper in Aesthetic Surgery Journal described the earliest protocol as delivering the maximum tolerable energy in a single pass, which produced wide variation in outcomes and significant discomfort. That same paper estimated improvement at roughly 5 to 20 percent while noting that an individual patient's result was difficult to predict, and it stressed setting realistic expectations in advance.
Practice then shifted toward lower energy delivered across more passes. A 2009 review by M. Elsaie in the Indian Journal of Dermatology summarized that early protocols used 100 to 150 pulses across the full face and neck, while later guidance moved toward 400 or more pulses for the same area, and that multiple lower-energy passes produced better outcomes with less discomfort.
A prospective study of Asian patients, archived in PMC, the National Institutes of Health's article repository, treated 30 patients with mild to moderate lower-face laxity using a single monopolar radiofrequency session. The average shot count was 412±49, delivered across 3 to 4 passes at energy levels 2 through 4, overlapping each pass by 15 to 30 percent. The prior analyses cited within that paper found that outcomes tended to improve as pulse count increased.
A shot count becomes meaningful only alongside the energy per pulse, the number of passes, and how much each pass overlaps the last. Our Seocho location's OligioX device is also radiofrequency-based; per our own treatment guide, it uses 6.78MHz energy to stimulate dermal collagen. Even within radiofrequency, a device's design sets its own basis for what a shot count means.
A Price List Doesn't Show the Design Behind It
A price list is usually written as "device name plus shot count plus amount." That single line doesn't show which area is treated, at what depth, or across how many passes. Two treatments priced identically can be addressing two different areas entirely.
At our Seocho location, every device and injectable is a genuine, unopened-in-front-of-the-patient product, and we confirm that at the start of each session. Our physicians perform lifting, skin booster, and anti-aging treatments themselves. Cost information is available in advance through the pricing guide on our Seocho website, and the final plan is set in consultation, once the area and design have been diagnosed and explained.
How a Seocho Consultation Is Structured
In the Star Daily News interview marking our Sofwave introduction this May, I said that a treatment plan needs to fully account for a patient's individual skin characteristics and pattern of aging. That's the order our consultations follow.
Identify the area of concern and the pattern of sagging. We check whether the cheeks, jawline, double chin, or under-eye area is the primary concern, and whether the sagging is structural tissue laxity or a loss of surface elasticity.
Assess skin thickness and fat volume. This determines whether treatment should reach the fascia layer or stay dermis-focused.
Review treatment history. What device was used, and when, affects spacing and whether treatments can be combined.
Confirm scheduling and recovery timing. A flight home or another commitment can change which device and intensity make sense.
Set the device, depth, energy, and shot count last. Only at this point do we decide the number, and we explain how it's divided across area and layer.
If you hear a shot count in a consultation anywhere, these are reasonable questions to ask: which area and depth is this number divided across? What energy level is being used? Can the product packaging be opened and confirmed before treatment? Who is performing the procedure? We answer each of these directly during a Seocho consultation.
FAQ
If I get the same shot count as last time, will I get the same result?
Not necessarily. Skin thickness and elasticity change over time, and the 2005 Aesthetic Surgery Journal paper on monopolar radiofrequency noted that individual outcomes are inherently difficult to predict. Bringing records of a prior treatment's device, depth, and shot count helps us compare against your current condition and adjust the plan.
Should I ask for a lower shot count if I'm worried about pain?
Adjusting the energy level is usually considered before reducing the count. The 2009 Indian Journal of Dermatology review found that dividing lower energy across more passes reduced discomfort, and it emphasized monitoring a patient's pain response throughout the session to avoid excessive heat delivery. Tell us right away if you're uncomfortable during treatment.
When can I actually judge whether a treatment worked?
A 2024 study in the journal Cosmetics explains that monopolar radiofrequency's heat contracts existing collagen immediately, with dermal remodeling and new collagen formation following over a longer recovery period. That's why studies evaluate results weeks to months out. The ultrasound study cited earlier checked outcomes at 12 and 24 weeks; the radiofrequency study in Asian patients checked at 1, 3, and 6 months. We recommend not judging a shot count by how treatment feels immediately afterward.
How do I find out which lifting devices are available at the Seocho location?
Our Seocho website's treatment menu lists the devices currently offered, including Sofwave, Ondamed, OligioX, and Vero. Which one fits your case is decided together, after diagnosis, based on the area and layer involved.
