WEDNESDAY, Feb. 21 (HealthDay News) -- Skin regeneration using a low-energy device improves the appearance of photodamaged facial skin with minimal downtime, researchers report in the February issue of the Archives of Dermatology.
Melissa A. Bogle, M.D., from SkinCare Physicians in Chestnut Hill, Mass., and colleagues treated eight volunteers with photodamaged facial skin with a U.S. Food and Drug Administration-approved low-energy plasma skin regeneration device (sold as Portrait PSR). The individuals received a total of three full-face treatments given three weeks apart. Changes in facial appearance were assessed through photographs, and skin biopsies were taken to assess skin regeneration.
Three months after the last treatment, the researchers found that there was a 37 percent reduction in facial rhytids, and the volunteers reported a 68 percent improvement in facial appearance. The skin biopsies showed that new collagen was present at the dermoepidermal junction and less dense elastin was present in the upper dermis. Re-epithelialization occurred within four days after treatment, and patients reported redness for an average of six days. There was no scarring or hypopigmentation, the authors note.
"Plasma skin regeneration using the multiple low-energy treatment technique allows significant successful treatment of photodamaged facial skin with minimal downtime," Bogle and colleagues conclude. "Results are comparable to a single high-energy treatment, but with less healing time."
