The Reaction, a new multi-frequency
radiofrequency (RF) system for body
contouring from Viora, Inc. (Jersey City,
N.J.), is receiving favorable response
from both physicians and patients. The
backbone of this bi-polar device is patented, Channeling Optimized Radiofrequency Energy (CORE) technology,
which embodies four distinct frequency modes to precisely control RF penetration depth in underlying tissue.
“From a scientific point of view, the
Reaction has the potential to achieve
more diffuse volumetric heating to all the
tissue layers because of its multiple frequencies,” reported Neil Sadick, M.D.,
a clinical professor of dermatology at
Weill Cornell Medical College in New
York City, N.Y. “It’s sort of like a multi-dimensional treatment for cellulite, body
contouring and skin tightening.”
Unlike monopolar RF energy that uses
a single electrode, bi-polar RF energy
incorporates two electrodes. “Monopolar
energy is dissipated down into deeper
tissue, but in a more non-controlled fashion, whereas bi-polar allows the energy
to be generated between the two electrode plates, so delivery is more controlled,” Dr. Sadick noted. “Theoretically,
bi-polar RF energy may also be safer
than monopolar RF energy because it is
more controlled.”
Similarly, the benefits of multi-frequency capability as opposed to single
frequency technology include flexibility, reduced treatment time, potentially
safer treatment and enhanced patient
comfort. “Multi-frequency provides the
ability to have the energy dissipated at
various layers of the skin,” Dr. Sadick
said. A full face takes 30 minutes with
the Reaction versus around 60 minutes
with single frequency devices, which
also translates into faster healing. Patient
comfort is achieved when treating shallower areas, such as the forehead and
THE Aesthetic Guide September/October 2010
around the mandible, when used with
the appropriate frequency.
Ideal candidates for the Reaction are
those who desire improvement in cellulite,
circumferential reduction of a limb and
tightening of skin (e.g., belly or face).
Patients seeking contouring treatments usually schedule six to eight treatment sessions, once every week. After a series,
patients can expect a 1 cm to 3 cm circumferential reduction of their thighs, for example; improved contour of cellulite; and
some tightening (abdomen, thighs and
chin). Patients seeking tightening treatments usually schedule three to five treatment sessions, two to four weeks apart.
“Patients are happy,” said Dr. Sadick,
who has been using the Reaction since
February 2010. Most people require a
single maintenance treatment, once or
twice a year.
The Reaction also combines vacuum
therapy in its body contouring treatments
to allow even deeper delivery of RF energy. In addition, vacuum has been shown
to “improve blood flow circulation, lymphatic drainage and oxygen delivery
to cells,” Dr. Sadick stated. “Although
we don’t know the exact cause of cellulite, conditions that improve the parameters of cell metabolism may play
a secondary role.”
An in vitro clinical study conducted on
the skin of domestic porcine found that
the Reaction influenced heating at a depth
from 3.9 mm to 18.6 mm. This is being
followed up by a single site, human clinical trial of 15 patients for facial skin tightening (three sessions spaced two weeks
apart). “Treatment is relatively painless,
and it appears we can effectively treat
from the mid-dermis down through the
subcutaneous layer, for customizing
treatment programs,” said Dr. Sadick,
the principal investigator. “Treatments
are uniform and safer.”
