A study by investigators at New York Hospital-Cornell Medical Center
and Duke University Medical Center confirmed the EpiLight Hair Removal
System effectively destroys hair follicles.
Study participants, numbering in the thousands over a three-year
span, experienced no significant hair regrowth after 20 months,
said Neil S. Sadick, M.D., lead author of the study and a practicing
dermatologist in New York. With more than two years of follow-up,
hair removal efficiency was found to be 68 percent after an average
of three treatments per patient.
The difference with the EpiLight broad spectrum flashlamp vs.
other lasers on the market is that it has a broader spectrum of
wavelength, with penetration to deeper, thicker hairs and darker
skin types, said Dr. Sadick. The EpiLight broad spectrum flashlamp
destroys from the hair bulb to the hair bulge - the entire area.
This causes cell death, rather than a change in the programming
of the cell cycle.
According to the independent and peer-reviewed study published
in the Archives of Dermatology (1999 Jun;135(6):668-676), the objective
of the study was to examine the clinical, histological, and mechanistic
effects on skin with the EpiLight hair removal method.
The study focused on evaluating the morphologic changes occurring
at the cell or tissue level and assessing the involvement of well-known
proteins in the cell cycle, so that experts can more effectively
identify specific changes associated with effective hair removal
and achieve a better therapeutic outcome.
Study Group Numbers
The study group included 10 men and 57 women with areas of excess
body hair. Nine subjects received a single intense pulsed light
treatment and 58 received multiple treatments. No anesthesia or
postoperative care was required.
The mean hair loss in patients who received a single treatment
was 48 percent at six months or more. Subjects who received multiple
treatments experienced a mean hair loss of 64 percent at six or
more months. The treatments were well tolerated, with no serious
effects, or pigmentary or scarring complications.
Histologic findings showed no significant hair regrowth up to
20 months after treatment.
Conclusion
Researchers concluded the EpiLight Hair Removal System, manufactured
by ESC Medical Systems of Yokneam, Israel, results in: persistent
epilation for more than six months after single or multiple treatments;
no significant hair regrowth at 20 months after treatment; and optimal
selective thermal damage.
