Feb. 20, 2007 -- Multiple low-energy treatments with a plasma skin
regeneration tool may be an improvement over high-energy treatments for facial
A new study shows that multiple low-energy plasma skin regeneration
treatments may have about the same wrinkle-reducing effect as one high-energy
session -- and with less healing time.
During plasma skin regeneration, energy from plasma rather than light or
radiofrequency is delivered to skin tissues. The energy stimulates new skin
growth in the targeted area and can be used to reduce the appearance of
wrinkles or superficial skin lesions.
Researchers say previous studies have focused on using the technology in
single, high-energy treatment, which can be effective but also take up to a
week or more for healing.
The study, published in the Archives of Dermatology, looked at the
effects of three full-face low-energy plasma skin regeneration treatments given
to eight participants.
Three months after treatment, the results showed that the participants had
37% fewer wrinkles, as judged by the researchers. Overall, the volunteers
reported a 68% improvement in facial appearance.
Researchers found new skin tissue had regrown over the treated area about
four days after treatment, and patients said skin redness lasted about six
days. No scarring or loss of pigment was reported.
When researchers examined the treated skin tissue under the microscope, they
found a new band of collagen, the primary protein in skin, had formed in the
inner layers of skin.
“The healing time in our study averaged approximately five days per
treatment; however, this was a patient-assessed number that included days it
took for any residual redness and peeling to completely resolve," writes
researcher Melissa A. Bogle, MD, of the Laser and Cosmetic Surgery Center of
Houston, and colleagues. "While nearly a week of healing time may not seem
to be an improvement over other minimally invasive resurfacing procedures and
micropeels, the intensity of the healing process is quite minor, which makes it
an attractive option for many patients."
