1. What is Ultrasound
and is it audible?
- Ultrasound is a
continuous cycle of sound waves at a frequency (≥ 20KHz) which actually is, by definition, beyond the upper limits of the human
auditory sense. However, researchers have shown that the younger
age groups do have the capacity to hear some spectrums of ultrasound
waves, but that ability generally diminishes with age.
2. Is Ultrasound safe?
What are some medicinal applications of Ultrasound technology?
- Ultrasound technology is absolutely
safe when used as directed. In fact, it has a long history of use in
medicine. For example, Medical Sonography Imaging is commonly used
during pregnancy to determine the health and development of an unborn
fetus. Both Focused Ultrasound Surgery (FUS) and High Intensity
Focused Ultrasound (HIFU) have been used in the treatment of both benign and
malignant tumors. Focused ultrasound sources are also tools used
in the treatment of cataracts, dislodging of kidney stones, teeth
cleanings, physical/occupational therapies, liposuctions, tooth
and bone regenerations, elastography, etc. Ultrasound has also
been shown to have synergistic effects with antibiotics in killing
bacteria. Ultrasound has been shown to facilitate the delivery of
drugs across the skin, promote gene therapy to targeted tissues, deliver
chemotherapeutic drugs into tumors and effectively deliver thrombolytic
drugs into blood clots. Additionally, ultrasound has also been
shown to facilitate the healing of wounds and bone fractures [Ref. 1].
Many of these examples have been FDA-approved for many years now, while
others are in the later stages of Clinical Studies.
3. How do Ultrasonic Health & Beauty
Devices work in conjunction with topical compounds?
-Transdermal delivery of topical
compounds using Ultrasound has the potential to be an extremely
efficient delivery mechanism. Topical application avoids the
effects of both gastric degradation and hepatic first-pass metabolism.
The epidermis represents a large surface area for absorption, has relatively low proteolytic activity and is undoubtedly one of the most easily
accessible organs of the body [Ref. 2].
-Ultrasound energy produces a
mechanical pressure wave through soft tissue. This pressure wave may
cause microscopic bubbles in living tissues, and distortion of the cell
membrane, influencing ion fluxes and intracellular activity. When
ultrasound enters the body, it causes molecular friction and heats the
tissues slightly. This effect is very minor as normal tissue
perfusion dissipates heat. With high intensity, it can also cause
small pockets of gas in body fluids or tissues to expand and
contract/collapse in a phenomena called microcavitation [Ref.
Ultrasonic cavitation alters the structure of the lipid bi-layer of the
stratum cormeum by washing away the fats and oils holding the
skin intact and removing the dead
skin cells. The process creates
reversible micro channels (about 25-125 microns, which is smaller than
the width of a
strand of hair) through which medicines or topical nutrients can be
delivered and analytes extracted, all without the use of needles.
The skin returns to its initial state in
24 to 48 hours. The overall effect of Ultrasound energy is to
enhance the penetration of the topical compounds while exciting their
molecular compositions to drastically augment their therapeutic potency.
4. What are the effects of using
Ultrasonic Health & Beauty Devices?
-The use of
ultrasound devices in treatments have three major effects [Ref. 4]:
Mechanical effects: The mechanical effects include the very
important micro-massage of tissue, softening of scars, increased
superficial toning, and increased elasticity of the skin.
Thermal effects: The thermal effects of ultrasound create
friction and increase local heat. By increasing the metabolism of
fibroblasts and other connective tissue cells, production of collagen
and elastin increases. Increased temperature also stimulates blood
flow to the area, bringing with it more oxygen and nutrients for
healing. Another benefit of increased blood flow is an increase in
lymph flow, which aids in removing toxins and waste products.
Chemicals effects: Ultrasound helps increase
the rate of chemical reactions in cells to facilitate healing. It
also decreases the local pH and increases the permeability of skin
cells, effects that favor the penetration of active ingredients in the
5. How do I maximize these
waves do not conduct well through air. They need a medium (such as
liquid/gel) to produce an effect.
For product penetration, if the active ingredients you are using
dries quickly or produces friction between the blade and skin, you might
not get the all the benefits of the above effects due to a shortened
treatment time. The best thing to do is after applying the active
ingredients to the skin, add a bit of conductive gel to the skin surface
and proceed with the treatment. But if the product you are using
already comes in a gel-form, you do not need to use a conductive gel.
The most important thing to remember is that ultrasound waves needs a
conductive medium through which to travel through.
6. Why can't I feel your
Ultrasonic Health & Beauty Devices get hot or vibrate during usage?
-We commonly encounter the following
question at Tradeshows, "How come
our ultrasound probes are not hot and
the vibrations cannot be felt when one puts their skin against the
surface?" The answer is simple; ultrasound waves do NOT
generate heat or induce thermal changes at the surface (neither the skin
nor the probes). The principle behind Ultrasound Therapy is that
ultrasound waves penetrate the skin to warm the area underneath it to
achieve its purpose (the depth of penetration is dependent on the
intensity level of the probe).
therapeutic ultrasound waves at the correct frequencies are only
supposed to produce microcavitation/microvibration
causing deep micro-heating locally,
which is VERY rarely felt by the client/patient.
The physical effects of both microcavitation/microvibration are
not generally perceptible to touch either. Therefore,
ultrasound probes that are noticeably hot and/or vibrate are definite
signs that the energy output level is too strong and thus will not
provide beneficial results. Unfortunately, this is the case all too often
as most of the less expensive ultrasonic devices currently available in
the marketplace (commonly manufactured in China) fall into this category.
If a burning sensation
or pain occurs during or after a treatment using an ultrasound probe,
immediately stop using the device because the device has not been calibrated
correctly and is not within the FDA safety guidelines.
important when shopping for an ultrasound device, to make sure that
the distributor knows the exact specifications of their products.
7. How do I know whether my
Ultrasonic Health & Beauty Devices are functioning properly?
- To test the Skin Spatula, simply
turn on the device (to clean mode) and drop some water onto the surface
of the blade tip. As long as the water vaporizes upwards, it is
-To test our line of ultrasonic
massagers, there are two tests you may perform. The first test is similar to the Skin
Spatula test, where you place a
few drops of
on the probe and turn it on.
If the water vaporizes, then the unit is fine. The second test
is also quite simple. Place some lotion on the probe and gently
massage it onto the back of your hand in slow concentric circles for at
least two minutes. After at
least two minutes of massage, place the probe on another part of your
body (generally the upper forearm), the probe
should feel cool to the touch, but when you place it back onto the massage site,
you should feel a slightly warmer sensation.
8. Is the blade of the Skin
Spatula hand-piece supposed to be hissing during operation? Why do
I have to send the entire Skin Spatula Unit back when all I need is a
-The hissing sound from the blade is
caused by the vibration of the blade. This is normal for the
device to function in this way. Every hand piece has a different
frequency within the range of 24 KHz to 28 KHz. We adjust every
main machine to match the frequency of the hand piece. This is one
of the reasons why when your hand piece needs to be replaced, the entire
unit must be returned so that the main machine is recaliberated to match
the new hand piece.
9. How exactly do your
Ultrasonic Health & Beauty Devices generate ultrasound waves?
-Ultrasonic sound can be produced by
transducers which operate either by the piezoelectric effect or the
magnetostrictive effect. The magnetostrictive transducers can be
used to produce high intensity ultrasonic sound in the 20-40 kHz range
for ultrasonic cleaning and other mechanical applications.
skin spatula/scrubbers have a frequency of
around 25 KHz. The PZT ceramic crystals are on the blade part that
is contained in the casing. There are 3 PZT crystals on each side
of the blade which makes the blade oscillate once electricity goes
through. Due to blade oscillation, a high-pitched sound is
generated that some can hear while others cannot. We have observed
actual sound sensitivity at trade shows, when we power on the machine
for demos. Some people cannot bear to be near the device because
of the discomfort. Others do not even hear a thing. Other
ultrasound probes are usually only 1, 2, or 3 MHz with one PZT crystal
that vibrates up and down so no high-pitched sound is generated.
-If the ultrasound device only has 1 PZT
ceramic crystal, people normally do not hear anything. The
has 6 PZT ceramic crystals: 3 on each side of the stainless steel blade
(the part enclosed in the handpiece). The current used to trigger
the crystals' vibration is different in timing for each side. This
produces two different sound waves which is efficient for cleaning the
skin. With the size of the
stainless steel blade being vibrated, it will often make the high pitch
sound. The technique used to adhere the ceramic crystals to the
blade is also a factor with the production of a high pitch noise.
10. Are there
contraindications of therapeutic ultrasonic devices in general?
-As far as we know from our literature
research, there are no contraindications to operators of the ultrasonic
devices. However, certain medical conditions do exist that prevent
the usage of ultrasound as a therapeutic on clients/patients.
These conditions include
circulatory deficiency, malignancy, pregnancy (directly over
abdomen) , or acute/severe
infection. Additionally, the ultrasonic applications should never
be administered over the eyes, heart (especially for those with a pacemaker),
spinal column, growing bones, testes, growth plates of children, carotid
sinuses, cervical stellate ganglion, and vagus nerve. It is
extremely important to note that the head of the ultrasound probe must
kept in constant motion at all times during administration to prevent an
excessive buildup of focused ultrasound energy.
Do I need to use a Galvanic System with the Ultrasonic SkinSpatula?
What is the difference between Ultrasonic and Galvanic Penetration?
-The quick and simple answer is "No." A Galvanic System is not
necessary (though it can be used if desired) when an Ultrasonic System
is in use because the two Systems utilize two completely different laws
-The purpose behind the use of a Galvanic System is to utilize the flow
of ions (in this case electrons) to draw some formulation of the skin
care product into the skin by simulating the creation of a closed
circuit loop. This System works because essentially all chemical
compounds dissociate into their ionic derivatives when in solution (in
both liquid and gel mediums). Therefore, an electrical charge from
a circuit would literally pull/attract ions of the opposite charge
toward it (or deeper into the dermis), while repelling ions with similar
charge (out of the body). For example, visualize this electrical
charge-to-ion interaction as magnets that either repel or attract each
-On the otherhand, none of these
charge-to-ion interaction matter at all when an Ultrasonic System is
used. Ultrasound utilizes sound energy in the form of sound waves
to disrupt the assembly of the dermis/epidermis cells to create channels
in the skin to BOTH draw out cellular debris and dead skin cells AND to
penetrate the skin care product.
