The Linear Z Program is a custom-designed lifting treatment that uses focused ultrasound energy for a gentle, non-surgical facelift. It offers 2 delivery modes — Dot Mode for point-by-point focus and Linear Mode for smooth, continuous energy lines — allowing doctors to adapt each session to your skin’s needs.1
With treatment cartridges (Linear Z Program tips) ranging from 1.5 mm to 13.0 mm, the Linear Z Program can be applied to both facial contours and body areas that benefit from firming.1-2 This flexibility helps support natural collagen remodeling while keeping results subtle, balanced, and in harmony with your features.
Clinical studies and data suggest that visible improvements typically develop gradually within 1–3 months and may last 6–12 months, depending on individual skin condition and lifestyle.2-3
At BSL Clinic, the Linear Z Program is approached as more than a device-based treatment.
Each session is thoughtfully planned based on individual skin structure, fat distribution, and treatment goals — allowing ultrasound energy to be applied in a balanced, measured way that supports natural-looking results.
This approach is reflected through 4 personalised lifting strategies, selected and combined during consultation to align with each person’s skin type, facial structure, and desired outcome.
Linear Z Program completes up to 300 shots in about 1.2 minutes, helping shorten each HIFU lifting session by around 40% while maintaining smooth, even energy delivery.
Distributes ultrasound energy precisely, reducing excess heat spread and supporting a smoother, more comfortable treatment experience.
Uses an Automatic Position Feedback Sensor to monitor energy output, helping maintain consistent energy delivery throughout each session.
The Linear Z Program integrates both Dot and Linear ultrasound modes in one handpiece, allowing precise energy control at different depths.
The Linear Z Program works gently from face to body — using precise HIFU energy to refine contours, improve firmness, and enhance natural skin balance.
Each zone receives customized ultrasound care, supporting a smoother, more defined appearance — the essence of a non-surgical face lift.
– Lifts and refreshes the upper face for a naturally awake look
– Smooths fine lines and maintains elasticity around delicate skin
– Refines jawline definition and improves cheek firmness
– Helps reduce double chin and smooth sagging around the lower face
– Firms and smooths skin along the neck and upper chest
– Supports a seamless, youthful transition from face to body
The Linear Z Program extends beyond facial lifting — offering gentle body contouring through controlled HIFU energy that supports fat balance and skin tightening across key body areas.
– Arms: Helps tighten mild laxity for a more toned look
– Abdomen: Supports firmer, smoother skin texture
– Thighs: Improves elasticity in areas prone to sagging
In summary, the Linear Z Program refines skin from every layer — helping balance fat, collagen, and elasticity for a lifted, refreshed look that feels naturally yours.
When people think about facial lifting, many imagine it means “melting fat.”
In fact, fat is one of the most important layers supporting your skin — helping maintain a youthful, naturally lifted contour.
Beneath the surface are tiny fat compartments that interact closely with collagen and elastin, the key proteins that keep your skin firm and elastic.2
Think of it as a system that rebalances your skin from within — not by removing fat, but by guiding it to behave more harmoniously.
Over time, these fat cells gradually lose activity as inflammation and aging slow down their natural renewal. When this happens, both skin firmness and facial volume decline — leading to visible sagging or hollowness.5
The Linear Z Program is designed to help rebalance this process through custom-designed HIFU lifting, harmonizing how fat, collagen, and elastin work together beneath the skin for smoother, naturally firmer results.
The Linear Z Program is built on the principle of fat balance and structural harmony.
Instead of destroying fat cells, it gently refines their behavior using precise ultrasound energy — helping balance fat, collagen, and elastin beneath the skin.
This balanced approach helps maintain the skin’s natural firmness and flexibility, resulting in a lifted, refined contour without the need for surgery.
The Linear Z Program uses a multi-depth cartridge technology to deliver energy precisely across different skin layers — from the surface to deeper fat tissue.
Each cartridge is designed for a specific zone, supporting customized lifting, fat balance, and skin tightening across the face and body.
Targets the delicate eye and upper face areas, improving elasticity and radiance.
Reaches the SMAS layer, firming the foundation for a natural V-line appearance.
Works on body areas such as arms or abdomen to enhance overall tone and firmness.
Stimulates collagen remodeling and mild lifting in thinner skin zones.
Helps refine localized fat under the jawline or cheeks for a smoother contour.

This multi-layer approach ensures the Linear Z Program adapts to your unique skin structure — achieving natural, even lifting from surface to depth.
Dot Mode works through pinpoint spots of energy beneath the skin, delivering focused warmth to the SMAS layer — where firmness and lift naturally begin.
This mode is designed to :
In addition to lifting and collagen renewal, Dot Mode helps the skin naturally maintain its volume and contour.
This gentle HIFU energy supports the fat layer — a process known as Fat Proliferation, restoring balance between fat, collagen, and elastin over time.2
The Linear Z Program delivers gentle ultrasound energy (0.2 J) to activate thinner fat layers beneath the skin.
Instead of destroying fat, it encourages a natural response called fat proliferation — helping the tissue become denser and more balanced over time.
Every face is unique — and so is the way each layer of skin responds to treatment.
At BSL Clinic, the Linear Z Program is planned with an understanding of overall skin and facial structure, allowing it to be performed with care — either on its own or alongside other treatments when appropriate.
Rather than replacing other procedures, it can be integrated in a measured way to help support balance between lifting, firmness, and skin texture from within.
When structure meets balance, the result is a more refined lift.
This pairing lets doctors tailor the approach for every contour :
Together, they work in a complementary way — lifting from the foundation while refining balance at the surface.
The outcome: a natural, multidimensional result where firmness, smoothness, and radiance coexist in harmony.
Every face tells its own story — and balance is what keeps it timeless.
While the Linear Z Program refines skin quality from within, the Dermal Filler Program restores natural structure and smooth transitions on the surface.
Together, they create a complete approach — improving both the foundation and the form of the skin.
This combination allows doctors to tailor results more precisely:
Together, they refine facial shape and surface texture, creating balanced, natural results.
The Linear Z Program is designed for those seeking a non-surgical HIFU face lift that works gently and precisely beneath the skin — helping refine facial contours while supporting natural balance from within.
With its Dual Mode Technology — combining Dot Mode for precise lifting and Linear Mode for balanced fat control — the Linear Z Program allows doctors to tailor each session to your unique skin condition, structure, and treatment goals.
Results naturally evolve over time as collagen renewal continues, with visible improvements that stay consistent for several months depending on your skin condition and care routine.
Unlike traditional HIFU, the Linear Z Program features Dual Mode Technology — Dot Mode for targeted lifting and Linear Mode for balanced fat control and skin rejuvenation.
The Linear Z Program improves skin laxity, uneven contours, and double chin while enhancing collagen and elastin activity for natural rejuvenation — helping the skin look brighter and healthier over time while maintaining natural facial volume balance
A typical session lasts around 40–60 minutes, depending on the treatment area and goals.
Most individuals can return to normal activities immediately. Temporary redness or mild tenderness may occur but typically subsides within a short time.
Most people describe the sensation as mild warmth or tingling. The energy delivery is carefully controlled to maintain comfort during treatment.
It can be applied to the face, jawline, neck, and even certain body areas like the arms or abdomen for gentle contouring and tightening.
Yes. The Linear Z Program can complement other aesthetic treatments for a balanced, naturally refreshed look.
It supports lifting, fat balance, and skin elasticity through gentle ultrasound energy — and can be paired with the Ultherapy Prime Program for deeper lift or the Dermal Filler Program for enhanced contour and radiance, all tailored to your individual goals.
Doctors adjust the mode (Dot or Linear), depth, and energy level based on the skin’s structure, fat layer, and individual treatment goals.
Yes. Because it uses ultrasound energy rather than light or laser, it can be performed on most skin tones and types.
Maintenance frequency varies. Some people repeat the treatment every 6–12 months to support ongoing collagen and fat balance renewal.
