Part I
Introduction
At present, a laser fat-dissolving machine is the most popular equipment for weight
loss and body slimming. It can effectively replace weight reduction programs in a
beauty salon, and can be operated easily, conveniently, and swiftly, and solves body
problems for people pursuing beauty. And this equipment works safely and effectively
and requires no injection, no medication, and no operation. It has no side effects and
is operated externally throughout and has an instant effect. Laser is of strong
penetrating power which can effectively activate or repair fat cells, penetrate fat layer,
and dissolve subcutaneous fat by heating. The treatment method is safe, painless, and
has no side effects.
Advantages
1. Laser strongly dissolves the fat and has an evident effect.
2. It asks for no operation and anesthesia.
3. It’s comfortable and painless during treatment. And it requires no convalescence
and will not affect work after the treatment.
4. No consumption, low cost, but with a quick return.
5. Unevenness, bleeding, and swelling will not occur.
6. Laser lipolysis, which is safe and painless, dissolves fat evenly, makes skin smooth
and flat, and leaves no marks.
7. The laser wavelength can penetrate the fat layer, and dissolve subcutaneous fat
by heating which then will be absorbed and discharged through natural body
metabolism.
Working Principle
It uses a red laser, a visible spectrum with a wavelength of 635nm-650nm. The
wavelength of the laser is of strong penetrating power which effectively activates and
repairs fat cells, penetrates the fat layer, and dissolves subcutaneous fat by heating.
The treatment method is safe, painless, and has no side effects.
It sends the low-level chemical signals of laser energy to fat cells and decomposes
triglycerides stored in the fat layer into free fatty acids and glycerol that are released
through the channel of cytomembrane. Fatty acids and glycerol are transported to
body tissue that produces metabolic energy. The release of fatty acids is a natural
response when the body needs the stored energy reserves, thus no unnatural
reaction will occur inside the body, nor does it affect or damage surrounding
structures like skin, blood vessels, and peripheral nerves. After some time of exercise
therapy, the free fatty acids inside the body will be eliminated through intact

metabolism.
Biological Effect: LED laser uses a laser of a wavelength of 635nm to 650nm which
heats fat cells in the targeted zone to decomposes them. And fat deposits are
absorbed and discharged via the body's natural metabolism in a short period. During
the process, the laser seals small blood vessels, reduces bruises, leads the heat to the
treatment area, and stimulates the production of collagen, thus flatness, smoothness,
tightening, and body shaping.
Low-energy laser(biological stimulation) directly reaches deep fat. It stimulates
biological cells and induces or strengthens a series of physiological reactions by
providing a proper amount of energy, including promoting local blood circulation,
regulating cell functions, enhancing immune function, and facilitating cell metabolism.
It can tighten skin, remove wrinkles, reduce fat, and shape the body simultaneously.
Laser is of strong penetrating power which can effectively activate or repair fat cells,
penetrate fat layer, and dissolve subcutaneous fat by heating. The treatment method
is safe, painless, and has no side effects.
