From Dr. John Shieh and the team at RejuvaYou Medical, serving South Pasadena, Pasadena, San Marino, Alhambra, Arcadia, and the San Gabriel Valley
The best non-invasive skin tightening treatment available in South Pasadena is one that stimulates the skin’s own collagen, elastin, and hyaluronic acid at the tissue level, with no downtime, no surgery, and a published clinical evidence base that supports every result. That treatment is Sofwave. At RejuvaYou Medical, we recommend Sofwave because the science behind it holds up to the health and wellness standard we apply to everything in our practice.
How Sofwave Works
Sofwave uses SUPERB (Synchronous Ultrasound Parallel Beam) technology to deliver controlled heat at precisely 1.5mm below the skin surface, the mid-dermis, where collagen, elastin, and hyaluronic acid are produced. The integrated Sofcool system protects the skin surface throughout treatment while the ultrasound works in the layer below.
The biological response builds entirely on your own tissue. New collagen for lift and structure. New elastin for resilience. Hyaluronic acid for deep hydration. Nothing added from the outside, only your skin rebuilding from within.
What the Published Evidence Shows
Sofwave is the most extensively published non-invasive skin tightening technology available today:
- 68 percent average increase in collagen confirmed by biopsy (Suh et al., 2025)
- 33 percent average increase in elastin confirmed by biopsy (Suh et al., 2025)
- Documented stimulation of hyaluronic acid production in the dermis
- 40+ peer-reviewed publications
- 865,000+ treatments worldwide — no fat atrophy events reported in published data
- 7 specific FDA aesthetic clearances
- Results lasting 12 months or longer from a single session
That safety record matters specifically because facial fat compartments give the face its structural volume. Sofwave targets the dermis at 1.5mm, above the fat layer, its mechanism is collagen stimulation, not fat disruption, which is why results look naturally refreshed.

Why Sofwave Fits the RejuvaYou Philosophy
At RejuvaYou, our focus has always been on health, wellness, and longevity, not just cosmetic results. Sofwave fits that philosophy because it works with your body rather than around it. The improvement comes from within, builds over time, and reflects the kind of long-term investment in skin health that our San Gabriel Valley patients are increasingly interested in.
Results build as new collagen, elastin, and hyaluronic acid mature, most noticeable between months 3 and 6, with results lasting 12 months or longer from a single session. Most patients achieve their goals with one treatment, with annual maintenance to sustain results over time.
