A pilot study on the use of a plasma skin regeneration device (Portrait® PSR3) in full facial rejuvenation procedures

Abstract

A new modality, the Portrait plasma skin regeneration (PSR³) system, allows precise and rapid treatment of photo-damaged skin, with controlled thermal injury and modification. Radio frequency (RF) energy converts nitrogen gas into plasma within the handpiece. Rapid heating of the skin occurs as the plasma rapidly gives up energy to the skin. This energy transfer is not chromophore dependent. The gold standard, carbon dioxide (CO₂) laser resurfacing, has decreased in popularity due to high morbidity and downtime. There is demand for a technology that can provide the degree of improvement obtained with resurfacing without the complications associated with its use. This study evaluated the PSR³ technology in full facial procedures. A two-site prospective study evaluated safety and efficacy for a single pass treatment of the full face using the Portrait PSR³ system. Improvement in skin texture, tone, fine lines, dyschromia, and rhytides were assessed. Two-millimeter punch biopsy specimens were taken pre- and 90 days post-treatment. Follow-up was performed at days 2, 5, 7, 30, and 90 post-treatment to monitor recovery, improvement, and any subsequent sequelae. Patients developed erythema and edema shortly after treatment, with no immediate epidermal loss or charring. Epidermal loss occurred in the subsequent 24–48 h followed by epidermal recovery in ∼7 days. Histological investigation showed regenerative epidermal and dermal architecture. The Rhytec Portrait PSR³ system provides an attractive alternative to standard lasers that is well tolerated by patients, stimulates collagen remodeling, and provides excellent clinical outcomes.
