Rosacea, Facial Erythema, Telangiectasias
By Erik L. Goldman
New York Bureau
Athens~ A series of full-faced
exposures with the PhotoDerm intense pulsed light systems is effective for
treating Rosacea, chronic facial erythema, and minor telangiectasias, with the
added benefit of a resurfacing effect, Dr. Patrick Bitter Jr. said at the 20th
Congress of the International Society for Dermatologic
Surgery. Dr. Bitter who pioneered and trademarked this
approach, terms the technique “FotoFacial.”
He has found it to be a major patient pleaser.
“The name differentiates it from laser ablation or
resurfacing, which scare some patients,” said the Campbell, California,
private practitioner. The technique
has a major advantage over laser approaches in that there is usually no visible
surface injury, minimal discomfort, and no patient
“downtime.” In evaluating the FotoFacial technique, Dr.
Bitter has had to rely on patient satisfaction and clinical examination, since
there are no clinically useful and reliable objective measures of flushing or
Rosacea severity.
He reported the results obtained
in a series of 30 patients with chronic flushing, rosacea, or telangiectasias
who underwent a full course of five treatments.
All of the patients said they had obtained some improvements in their
appearance, with 32% reporting that they were “very much improved.”
The remainder stated they were “much improved.”
Thirty-six percent said they were “extremely satisfied” with the
procedure, and none said they were dissatisfied.
Fifty-six percent of the patients with chronic erythema reported a 75% or
greater reduction in visible symptoms; the same percentage of rosacea patients
said they had a 75% or greater reduction in redness.
Forty-nine percent of the telangiectasia patients had a 75% or greater reduction
in visible vessels after treatment with PhotoDerm.
Many patients also saw a marked reduction in pore size, greater skin smoothness,
and a reduction in the depth and number of fine wrinkles.
In effect, FotoFacial is a non-laser resurfacing and rejuvenation
procedure. Histologically, the intense pulsed light
generates considerable new collagen formation.
In addition to the indication for
erythematous conditions, Dr. Bitter has also found FotoFacial useful for
“cleaning up” after laser resurfacing or dermabrasion.
FotoFacial involves five 20-minuate treatment sessions, in which the patient’s
full face is exposed to the pulsed light source.
Dr. Bitter recommends 3-week intervals between sessions.
To obtain optimal results, the
instrument settings are very precise. He
uses a 550-nm cutoff filter, with a double-pulse setting.
The first pulse I 2.4 milliseconds, followed 10 milliseconds later by a
second pulse of 2.4-4 milliseconds.
“These are very short pulses and delay time,” he said.
Total fluence is in the range of 30-36J/cm2.
“I know of no other therapy that
can improve flushing and rosacea to this degree,” he said, noting that
histologically, the pulsed light effectively obliterates both small and large
surfaces.
FotoFacial is extremely safe and well tolerated, he said.
The light exposure does cause a transient darkening of freckles or other highly
pigmented features, but usually resolves within a week.
Roughly half of all patients will
experiment some mild post exposure swelling, which resolves in 24 hours.
A small percentage of patients will have mild scabbing, that resolves in
2-4 days. He has not seen any major
adverse effects. The only significant downside is the cost,
said Dr. Bitter. The pulsed light
technology is quite expensive. A
new PhotoDerm intense pulsed light system from ESC Medical Systems in Needham,
Massachusetts, costs around $130,000.
In an interview, he said he bills
for the FotoFacial as a cosmetic procedure, even though in cases of rosacea or
telangiectasias, there is what some people would consider a medical
indication. Although it gives long-lasting results in chronic
erythematous conditions, it is not known whether or not FotoFacial will be a
permanent solution, Dr. Bitter said. The symptoms of rosacea
remain improved for at least a year after the last treatment session.
The main advantage of this
technique is that from the patient’s positions, there is very little burden in
terms of time or discomfort. The sessions seldom take more
than 30 minutes, and they do not require anesthesia. Patients can return to work right away; there is no prolonged
healing period--as there is with laser resurfacing or dermabrasion—in which
they must curtail their social activities.
Dr. Bitter has received payment for serving as a
preceptor for ESC Medical Systems.
