What Is the LinearFirm?
LinearFirm uses focused ultrasound energy delivered in precise linear patterns to tighten and lift the jawline, double chin, and neck area — without injections or downtime.
By targeting specific depths along carefully mapped lines, LinearFirm creates controlled thermal injury that stimulates new collagen formation exactly where it's needed for jawline definition and chin contouring.
- Focused ultrasound for precise jawline tightening
- Improves double chin and neck definition
- No needles, no downtime
- Progressive results over 8–12 weeks
What's Included in the LinearFirm?
Why Choose the LinearFirm?
LinearFirm delivers focused ultrasound in a line pattern rather than individual focal points, allowing continuous thermal zones that are particularly effective for redefining the jaw edge and softening the appearance of a double chin — areas that are difficult to address with RF or standard HIFU protocols.
- Specifically designed for jaw and chin definition
- No needles or downtime needed
- Visible jawline sharpening effect
How LinearFirm Ultrasound Works
The handpiece is moved along the jawline, submental (under-chin) area, and neck in linear passes. At each point, focused ultrasound creates a thermal coagulation zone at the precise target depth — triggering immediate collagen contraction and long-term remodeling.
The linear delivery pattern creates connected zones of collagen stimulation along the jaw edge, resulting in a tightened, defined profile as new collagen forms over the following weeks.
