How long does the treatment take?

It depends on the area and number of shots, but usually about 20-40 minutes. The exact time can vary from person to person.

Is it painful? Is anesthesia required?

You may feel warmth and slight prickling, but it is generally tolerable and can be done without anesthesia. If you are sensitive to pain, numbing cream is applied. Pain levels can vary from person to person.

Is there any downtime?

Downtime is short, so you can wash your face, wear makeup, and return to daily life right after. Temporary redness or swelling may occur but usually subsides quickly, and recovery can vary from person to person.

How many sessions do I need?

About 3 sessions at roughly 1-month intervals are generally recommended, but the ideal number and interval depend on your skin condition and goals. This too can vary from person to person.

How long do the results last?

When done on the recommended schedule, results are generally reported to last from several months up to about a year, though longevity depends on lifestyle and skin condition and can vary from person to person.

What is LinearZ?

LinearZ is a focused ultrasound (HIFU) lifting device developed by Jeisys Medical. It delivers ultrasound energy precisely to selected depths, from the dermis down to the SMAS (superficial musculoaponeurotic system), creating micro-coagulation points that trigger tissue contraction and collagen regeneration. A single cartridge supports both Dot and Linear modes, and the energy penetration depth can be selected in 0.5mm increments, so treatment can be tailored to each area and skin thickness.

How it works

One of LinearZ's core technologies is the DWR (Degassed Water Replacement) system. During treatment it continuously replaces and degasses the water inside the cartridge, helping ultrasound energy transmit evenly while keeping the cartridge's internal temperature stable. This temperature stability supports consistent energy output throughout the session. Combined with the Dot and Linear modes, our medical team can design anything from dense, wide-area lifting to focused tightening at specific points.

Key benefits

Lifts sagging cheeks and a blurred jawline for a more defined contour.
Stimulates the dermis and SMAS to encourage collagen regeneration and firmer skin.
Refines a double chin and loose neckline to support a V-line impression.
Smooths the texture of areas that show both fine lines and laxity.
0.5mm depth control allows precise work on delicate areas such as brow lifting.

Recommended for

Those who want to firm sagging facial contours without surgery
