Efficacy of Sofwave vs. XERF for Tech Neck and Submental Laxity?

I am currently researching non-invasive options for 'tech neck' and horizontal neck lines. I am specifically comparing Sofwave (SUPERB technology) and the newer XERF (multi-frequency RF). Given that we are now in mid-2026, I would value the perspective of plastic surgeons on a few points: • Precision vs. Depth: Sofwave targets the 1.5mm dermal layer specifically to avoid fat atrophy. Does XERF’s deeper reach provide a superior 'lift' for the neck, or does the risk to submental fat outweigh the benefit?  • Clinical Longevity: Sofwave has significant peer-reviewed data. For those who have integrated XERF over the last year, are you seeing comparable or superior long-term collagen remodeling at the 6-month mark?  • Tech Neck Specifics: Which energy modality do you find more effective for the specific 'banding' associated with tech neck? Thank you for your clinical insights!
