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.
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.
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.
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.
