Ultrasound has been used on the
field of medicine, while it began
on beautification only 15 years
ago. Surprisingly, the following
three wonderful efficacy of ultrasound
bring the ones who care about
beauty skin a brand new world:
Heat efficacy
Cavitation
Highly speed vibration (machinery
affect)
1.
The heat efficacy
The
heat is produced by vigorous friction
of the modules in speed vibration.
It is basically important to human
body. To healthy cells, heat supplies
energy and speeds metabolism, while
to unhealthy ones such as cancer cells,
heat weakens them and has them killed
easily. Cancer cells can not survive
at 43? and the lymphatic system works
well at this temperature. That is
why we usually kill cancer cells by
heat therapy. However, for protecting
healthy cells, almost all medical
and beauty ultrasonic devices equipped
the maximum output temperature and
the timer setting for auto switch-off.
The design is to rejuvenate our healthy
cells and hurt no body tissues.
According to the researches, massaging
with 1MHz of vibration for ten minutes,
the temperature of the skin texture
4-5cm deep into the surface would
go up 0.5-1 degree centigrade, and
with 1W/cm2 of continuous ultrasound,
0.007 degree centigrade up every second.
What does the heat do? It is not difficult
to consider that heat helps dissolve
the fat, that heat accelerates the
blood circulation, and also that heat
promotes sweat drainage. All these
are immediately concerned to our health.
2.
The cavitation
Stirring
the water in a fish jar with a chopstick,
we supply oxygen to the fish. The
speeder we stir, the more bubbles
we have. Now just image how many bubbles
would be produced by one million stirs
per second. That's right, countless
and invisible. But, each bubble still
does its best to do what a bubble
should do. They wrap all oil, stain
them up tightly, and remove them away
even from the pores of the face. You
do not have to worry about the composition
of the facial cleansers again, or,
if your face is cleaned well or not.
Ultrasound is deemed to take the place
of soap.
No doubt, skin cleaning is the most
important thing, especially for the
one whose skin is oily. Most of people
have tried and tried to find a perfect
facial cleanser but seem to get no
reward. Now, the cleaning method has
to be changed to make a breakthrough.
All we have to do is do a simple cleaning.
As to the oozed oil, bacteria, etc.
just leave to the ultrasound instead
of variety of soaps
3.
Highly speed vibration (machinery
affect)
The
first efficacy of ultrasound is the
highly speed vibration. Except in
vacuity, same frequency of ultrasound
would display various waveforms via
different transmissions. Their action
on the tissue is just like massage.
We usually call this machinery affect
as micro-massage. All other efficacy
is extended from this one, for example,
the heat efficacy and the bubbling
action.
The ultrasound applied in therapy
is usually ranged from 1MHz to 1000MHz.
Even the least vibration of 1MHz would
be as keen as a sharp knife to cut
off steels, if we reinforce its amplitude.
However, the output of the ultrasound
used in treating people must be decreased
substantially. The wave produced for
therapy and beautification is only
few micrometers high. One would feel
nothing but a little warm. It is better
for our tender textures. Appropriate
micro-massage plays a modulating.
