LinearZ
ReDerm Clinic features HIFU (High Intensity Focused Ultrasound) with LinearZ, the next-gen painless skin firming technique that uses focused ultrasound to lift and tighten without surgery.
Unlike traditional HIFU, LinearZ delivers energy in smooth, continuous lines—allowing for more even coverage, improved comfort, and greater precision, especially in delicate areas like the jawline, under-eyes, and neck.

LinearZ is versatile and can target multiple areas for lifting, tightening, and fat reduction.
The exact number of shots depends on individual anatomy and treatment goals.
For fat reduction (e.g., double chin), higher density linear shots are typically used.
For skin tightening, lower density dot or linear shots may be applied in combination.

LinearZ delivers continuous linear ultrasound energy, ensuring uniform heating and more consistent results. Traditional HIFU uses dot-based energy delivery, which can be less uniform and may require longer treatment times.
Most patients experience no discomfort during the procedure. The linear energy delivery method tends to be more comfortable than traditional dot-based HIFU.
LinearZ is a treatment you typically do once a year - though some may want added lifting 6 months later. The frequency depends on the number of shots done on the first session or if you have had significant weight loss - you may need another session earlier than the 12 month mark.
Yes, LinearZ is suitable for all skin types and skin tones.
Initial improvements may be noticed within a few weeks, with optimal results appearing after 1–2 months as collagen production increases.
