Hello! This is Seye Clinic, embracing all the beauty in the world.
When considering a LinearZ HIFU lifting treatment in Seoul, most patients ask whether 500 shots or 1000 shots are optimal. At Seye Clinic, we adjust between these two protocols based on skin laxity and area size, ensuring a customized approach that delivers visible lifting with minimal downtimeâoften just 0â1 days.
A patient recently visited our Gangnam clinic, pointing to their lower face and quietly asking, âWhy does my jawline feel so undefined lately?â Facial laxity is a gradual loosening of the skin and support structures, leading to sagging, jowls, and loss of contour. The core cause is a decline in collagen and elastin within deeper skin layers.
LinearZ is a HIFU (high-intensity focused ultrasound) technology. It works by delivering focused ultrasound energy past the skin surface, targeting the dermis and SMAS layer (the structural layer doctors rely on for surgical lifting). By forming small thermal coagulation points, LinearZ triggers your bodyâs natural collagen regeneration without needles or surgical incisions.
The signature feature of LinearZ is its dual delivery: dot mode (targets concentrated spots for precision lifting), and linear mode (covers broader areas more efficiently), both with selectable depths from about 1.5 to 13mm using four different cartridges. This allows us to precisely treat your unique facial structure, addressing both deep laxity and finer surface tighteningâwhether your concern is along the jawline, under the chin, cheeks, or even body zones needing firming.
For many patients, visible skin saggingâespecially around the jaw or cheeksâtranslates to a less youthful look. LinearZ aims to counter this with tailored intensity measured in shots, setting it apart from other modalities.

After performing numerous LinearZ treatments, one trend we often see is patients wanting an immediate answer: âDo I need 500 shots, or should I go for 1000?â The choice is not simply about more being betterâitâs about matching the shot count to your anatomy and goals.
Hereâs a direct comparison:
LinearZ 500 Shots | LinearZ 1000 Shots | |
|---|---|---|
Target Area | Smaller face/early laxity | Full-face/moderate laxity/larger area |
Intensity | Moderate | Higher (more lifting, deeper outcome) |
Duration | ~30 minutes | Slightly longer |
Downtime | 0â1 days | 0â1 days |
Pain Level | Mild | Mild to moderate |
Clinical Standard | Often first-time/maintenance | For advanced goals, more support |
LinearZâs flexibilityâthe ability to calibrate energy depth in 0.5mm steps, with four specialized cartridgesâhelps us fine-tune shot allocation. So, these numbers are starting points, not strict rules.
Importantly, both protocols maintain minimal downtime (0â1 days), meaning most patients resume daily life almost immediately, regardless of shot count.
Other non-surgical HIFU platforms such as Ultraformer, Shurink Universe, or Ulthera may use different shot protocols, but the dual mode (dot and linear) and precise depth control are unique strengths of LinearZ.
⢠Body firming: For areas like upper arms or abdomen, shot numbers may be adjusted furtherâbut we always adhere to the 500 or 1000 shot clinical standards at Seye.
A question weâre often asked is, âIf I double the shots, do I get double the result?â In our clinical experience, more shots allow more comprehensive coverage and deeper liftingâbut the outcome depends on your starting tissue laxity, skin thickness, and personal goals.
Pain and Comfort: Most patients tolerate the procedure easily, describing only mild to moderate discomfortâoften experienced as a momentary tingling or warmth at the treatment sites.
Downtime: LinearZ is renowned for its gentle recovery; whether 500 or 1000 shots, downtime is typically 0â1 days. Temporary redness or mild swelling may occur, but these resolve quickly.
Longevity: While results vary, most patients notice firmer contours progressivelyâwe see improvements continuing for weeks as new collagen forms.
Cost: Understandably, 1000 shots typically require more resources, so costs are higher. But for those who want a more pronounced jawline, lifted mid-face, or multi-zone treatment within a single session, the result often matches the investment.
⢠Our priority at Seye Clinic is to recommend the minimum effective shot count aligned with your true needsânever over-treating or overselling.
Being in Gangnam has unique advantages for cosmetic patients. Within a 1-minute walk of Gangnam Station, Seye Clinic offers not only modern accessibility but also clinical trust:
A thoughtful detail only an experienced LinearZ practitioner can offer: We use both the dot and linear modes in a custom sequence, often targeting deeper layers (SMAS) first, then feathering out with surface passes. This layered approach, combined with selectable depths from 1.5 to 13mm (fine-tuned in 0.5mm steps), means your treatment is highly bespokeâespecially important for international patients seeking natural, not âoverdone,â results.

Seye Clinic is known for personalized protocolsâwe do not automatically âupgradeâ everyone to 1000 shots but consider your anatomy, previous treatments, and expectations. Our lead doctors frequently review real-time feedback during the procedure, making fine adjustments for safety and efficacy.
Your journey begins with a personalized consultationâour doctor listens to your concerns, examines your facial anatomy, and discusses whether 500 or 1000 shots suit your needs. We then tailor the shot allocation and depth depending on where you need lifting, your skinâs thickness, and overall goals.
During the procedure (typically ~30 minutes), we utilize both LinearZâs dot and linear modes to first anchor lifting at key structural points (SMAS and ligament zones), then evenly blend the energy for smoother contouring. The use of four cartridges allows us to adapt to specific facial zones, offering both deep and superficial tightening.
Importantly, comfort and safety are priorities: We can adjust shot density based on feedback, and cooling gel is used throughout. Because LinearZ downtime is so short (0â1 days), patients often schedule the treatment before business trips or international travel.
What truly distinguishes the Seye experience is our KOL doctorsâ commitment to precise, measurable improvementâyou will see clear, stepwise changes in the mirror across your follow-ups, not guesswork or generic plans.
Q: How do I know if 500 or 1000 LinearZ shots are right for me?
A: At Seye Clinic, we determine the appropriate 500 or 1000 shots based on your skin laxity, facial area, and desired outcomeâafter a detailed consultation and assessment of your anatomy.
Q: Is there more pain or downtime with 1000 shots compared to 500?
A: While 1000 shots deliver more energy and coverage, most patients still experience only mild discomfort and minimal downtime (0â1 days) with either protocol, thanks to LinearZ technology.
Q: Can LinearZ be used for body firming as well as the face?
A: Yes, LinearZ is designed for facial contouring as well as body firming. We adjust the shot count and depth appropriately and always adhere to the 500 or 1000 shot standard for safety and effectiveness.
Q: What sets Seye Clinic in Gangnam apart for HIFU lifting?
A: Seye Clinicâs protocols are set by KOL doctors, utilize both dot and linear modes, and are based on MFDS-approved guidelines. Our locationâjust 1-minute from Gangnam Stationâadds convenience for international clients.
