How Sofwave Works

Sofwave delivers synchronized ultrasound energy through 7 parallel beams at a precise depth of 1.5mm in the mid-dermis, heating tissue to 60-70 degrees Celsius to trigger neo-collagenesis. The full-face procedure takes 30-45 minutes with integrated Sofcool epidermal cooling maintaining surface temperature below 40 degrees Celsius throughout treatment.
How Sofwave Works

Understanding the SUPERB Ultrasound Technology

Sofwave operates on Synchronous Ultrasound Parallel Beam (SUPERB) technology, an FDA-cleared system that generates 7 ultrasound beams simultaneously. These beams converge at a controlled depth of 1.5mm within the mid-dermis, creating thermal coagulation zones that measure approximately 0.5mm in diameter. The precise targeting distinguishes Sofwave from other ultrasound devices that penetrate to deeper layers like the SMAS at 3.0-4.5mm.

Each ultrasound pulse raises tissue temperature to 60-70 degrees Celsius for a fraction of a second. This thermal stimulus denatures existing collagen fibers and activates fibroblasts to produce new collagen and elastin over the following 12-16 weeks. The 1.5mm focal depth targets the collagen-rich reticular dermis while avoiding the deeper fat layers, nerves, and muscle tissue beneath.

Step-by-Step Sofwave Procedure Walkthrough

Pre-Treatment Preparation

The procedure begins with facial cleansing to remove all makeup, sunscreen, and oils. A thin layer of ultrasound coupling gel is applied across the treatment zones. Unlike some energy-based devices, Sofwave does not require topical anesthesia for most patients. However, practitioners may apply a numbing cream 20-30 minutes before the session for patients with heightened sensitivity, particularly when treating the periorbital or forehead regions.

During the Sofwave Session

The practitioner positions the Sofwave handpiece against the skin and delivers ultrasound energy in a systematic grid pattern across each treatment zone. Each pulse treats an area of approximately 14mm by 14mm. The handpiece is moved methodically across the forehead, temples, cheeks, jawline, and submental region. A full-face treatment requires 200-300 individual pulses delivered over 30-45 minutes. Treating the neck adds 10-15 minutes to the total session time.

Sofwave Comfort and Cooling System

The integrated Sofcool cooling mechanism is a defining feature of the Sofwave procedure. While the ultrasound energy heats the mid-dermis to 60-70 degrees Celsius, the cooling system simultaneously maintains the epidermal surface below 40 degrees Celsius. This 20-30 degree temperature differential protects the outermost skin layer from thermal injury while allowing full therapeutic heating at depth.

Patients describe the sensation during treatment as brief pulses of warmth with mild prickling. On a 10-point pain scale, the average reported discomfort level is 3-4 without anesthesia and 1-2 with topical numbing cream. The cooling system reduces discomfort substantially compared to older ultrasound platforms that lack epidermal protection. Treatment pauses between zones allow any accumulated warmth to dissipate.

Treatment Parameters and Session Planning

Energy levels during Sofwave range from 0.7 to 2.0 joules per pulse depending on the treatment area and skin thickness. The forehead and periorbital regions receive lower energy settings of 0.7-1.2 joules due to thinner tissue. The jawline and submental zones tolerate higher settings of 1.5-2.0 joules, producing stronger collagen stimulation in areas with greater skin laxity. Practitioners adjust parameters in real time based on patient feedback and tissue response.

Most patients achieve visible improvement from a single Sofwave session. Clinical data shows a 95% patient satisfaction rate at 12 weeks post-treatment. For moderate to advanced laxity, a second session may be scheduled 3-6 months after the initial treatment. Maintenance sessions every 6-12 months help sustain the collagen remodeling benefits long-term. At RE:BERRY Gangnam, Aesthetic Medicine Specialist Yoon-Gon Ryu tailors the treatment protocol to each patient's skin condition and aesthetic goals.

What Happens After the Procedure

Immediately following the Sofwave session, the coupling gel is removed and a soothing moisturizer with SPF 50+ is applied. Patients can resume daily activities including work, exercise, and social engagements without visible signs of treatment. There are no incisions, puncture marks, or bandages. The entire appointment from arrival to departure takes approximately 60-75 minutes including preparation, the 30-45 minute treatment, and a brief post-procedure skin check.

Frequently Asked Questions

What happens during a Sofwave session?
The practitioner delivers 200-300 ultrasound pulses across the face using a specialized handpiece over 30-45 minutes. Each pulse sends 7 parallel beams to a depth of 1.5mm, heating the mid-dermis to 60-70 degrees Celsius while integrated cooling protects the skin surface. No incisions or injections are involved.
How long does the procedure take?
A full-face Sofwave treatment takes 30-45 minutes of active energy delivery. Adding the neck extends the session by 10-15 minutes. Including preparation and post-treatment assessment, the total appointment lasts 60-75 minutes from arrival to departure. No recovery period is needed before leaving the clinic.
Does Sofwave hurt?
Patients rate Sofwave discomfort at 3-4 on a 10-point scale without numbing cream. With topical anesthesia applied 20-30 minutes before treatment, the score drops to 1-2. The integrated Sofcool system keeps the skin surface below 40 degrees Celsius throughout the session, significantly reducing the heat sensation felt during energy delivery.
How many sessions do I need?
A single Sofwave session produces visible tightening in 95% of patients within 12 weeks. Patients with moderate to advanced skin laxity may benefit from a second session at 3-6 months. Maintenance treatments every 6-12 months sustain collagen production long-term. Most patients require only 1-2 sessions annually to maintain results.
What technology is used?
Sofwave uses SUPERB (Synchronous Ultrasound Parallel Beam) technology, which generates 7 simultaneous ultrasound beams targeting the mid-dermis at 1.5mm depth. This FDA-cleared system includes integrated Sofcool epidermal cooling that maintains surface temperature below 40 degrees Celsius while therapeutic heating reaches 60-70 degrees at depth.
How does Sofwave differ from Ultherapy?
Sofwave targets the mid-dermis at 1.5mm depth using 7 parallel beams with integrated cooling, while Ultherapy reaches the SMAS layer at 3.0-4.5mm depth. Sofwave treats a 14mm by 14mm area per pulse compared to smaller focal points with Ultherapy. Pain scores average 3-4 for Sofwave versus 5-7 for Ultherapy without anesthesia.
Can Sofwave be combined with other treatments?
Sofwave pairs effectively with 3 or more complementary procedures. Combining with Ultherapy addresses both mid-dermal and deep SMAS layers simultaneously. Pairing with dermal fillers enhances volume restoration alongside skin tightening. Botox injections can be administered on the same day, targeting dynamic wrinkles that Sofwave does not address directly.
