The photothermal effect is the main mode of action of current
clinical laser applications. When heat energy acts on the surface
of a tissue, it will directly heat the tissue within an absorption
length. The heat is also conducted to the surrounding tissue
through thermal relaxation and is not conducted to adjacent
tissues. The heat vaporizes or removes tissue near the surface. The
rate of tissue removal depends on the concentration of laser energy
in the tissue. The higher the laser power, the faster the water
vaporizes and the tissue is removed, and the minimal heat damage
removes the tissue faster than the surrounding tissue underneath
the heat conduction, which ensures that the coagulation effect is
limited to the absorption length of the laser.
Generally speaking, after the first laser irradiation, the skin
surface will appear white bubbles. This change indicates that the
water in the cells has vaporized, leaving dry protein debris. When
these debris are washed away with salt water, obvious skin
shrinkage will occur. The skin has a yellowish appearance, and
these features are more obvious in thicker skin such as around the
mouth. There is significant shrinkage in thinner skin areas such as
the upper eyelids without obvious yellowing of the tissue. After
three or more irradiations, some yellow-brown dehydrated protein
denatured substances can be seen. These substances represent the
denatured collagen of the dermal reticular layer, and will appear
further thereafter. Carbonization and heat dispersion lead to
tissue necrosis.
Features:
Treatment principle and scope 1) Treatment principle: The thermal relaxation time of human skin
tissue is about 1-2 milliseconds. In order to effectively reduce
the scope and degree of thermal damage to surrounding tissue, the
laser pulse width must be compressed to less than 2 milliseconds,
and the pulse gap should be large. Greater than 2 milliseconds, it
is hoped that the surrounding tissue will be cooled during the gap
time after the pulse. The carbon dioxide laser therapy device is
developed according to such requirements. Because the pulse width
of less than 2 milliseconds is ultra-short compared to the pulse
width of several tens of milliseconds of ordinary therapeutic
devices, this pulsed carbon dioxide laser therapy machine that can
output ultra-short pulse width is referred to as a carbon dioxide
laser therapy device. The CO2 laser output beam is output through a focusing mirror. The
high temperature generated by the focusing point is absorbed by the
water in the cells and vaporizes the target tissue, thereby
achieving the purpose of treatment.
2) Treatment scope: Plastic surgery: laser skin resurfacing (rough skin, enlarged
pores, dull complexion, photodamage, etc.); laser wrinkle removal
(crow's feet, forehead wrinkles, Sichuan folds, nasolabial folds);
pigmented nevus, epidermal pigment spots (freckles, etc.), Cutting
of epidermal tags (all kinds of warts); scar repair (acne scars,
hypertrophic scars, linear scars, stretch marks, burn scars,
depressed scars, etc.); other applications (xanthoma, syringoma,
seborrheic Keratinization, etc.) Dermatology: removal of excess material and treatment of moles and
body odor Gynecology: cervical erosion Otology: Removal of nasal polyps Urology: circumcision, genital warts Anorectal: Hemorrhoidectomy Physiotherapy Department: Skin numbness, periarthritis of the neck,
periarthritis of the shoulder, arthritis, using beam expander
Carbon dioxide (CO2) 10600 nanometer laser machines have many
features in the field of skin beauty, including: 1. **Efficiently remove wrinkles and scars:** CO2 laser can
penetrate deep into the skin, stimulate collagen regeneration, and
effectively remove wrinkles and scars. 2. **Improve skin texture:** CO2 laser can promote the exfoliation
and regeneration of skin epidermis, improve skin texture, and make
skin smoother and more delicate. 3. **Wide range of treatments:** CO2 laser is suitable for treating
a variety of skin problems, including acne scars, pigmentation,
crow's feet, etc. 4. **Quick Recovery:** Although the skin needs a certain amount of
time to recover after CO2 laser treatment, the recovery time is
shorter compared to traditional surgery. 5. **High safety:** Under the operation of professional doctors,
CO2 laser treatment is safe and effective. Treatment parameters can
be adjusted according to individual conditions to minimize side
effects. 6. **Long-lasting effects:** CO2 laser treatment can usually
achieve longer-lasting effects, keeping the skin young and smooth
for a period of time. Overall, the CO2 laser 10600 nanometer machine is an effective skin
beauty device that can help people improve skin problems and
restore young, healthy skin.
After surgery: Ice compress: Reduce postoperative skin reaction. According to the
immediate reaction of the skin after different laser treatments,
apply cold wet compress or wrap ice cubes in gauze to ice the skin
after laser treatment. If the skin color turns white after
treatment, the ice compress time is about 30 minutes. If it is only
congestion, redness and swelling, the ice compress time is about 30
minutes. Wet compress time is 15 minutes, avoid rubbing the skin
during this process.
Replenish skin nutrients: Laser treatment will stimulate the
movement of cells and the release of nutrients, but it cannot
provide nutrients. In the traditional treatment method, only 0.9%
normal saline is used for cold and wet compresses to improve
inflammation, edema, burning, and tightness. There is discomfort
such as stretch, but the effect is often not ideal. This is because
our sebum film is different from the tissue fluid in the body, and
the skin needs more professional care products, such as growth
factors.
Sun protection: After using laser treatment and beauty technology,
the new skin in the treated area will become very sensitive to
sunlight. At this time, melanocytes are easily stimulated by light
to produce melanin and form pigmentation spots. In addition, new
skin is prone to photoaging after exposure to sunlight. Therefore,
after laser beauty treatment, sun protection is the key issue. Wear
a sunhat, cotton long-sleeved tops and trousers when going out, and
use a parasol. It is best to use an anti-UV umbrella, etc.; avoid
prolonged exposure to the sun during the strongest hours of the day
(10:00 to 16:00). You can also use sunscreen in moderation.
Diet: The role of diet in skin repair cannot be ignored. Protein,
fat and sugar are all necessary nutrients for the skin. Vitamins
and trace elements can affect the normal metabolism and
physiological functions of the skin. For example, B vitamins and
folic acid can increase pigment; vitamin C and vitamin A can
decrease pigment; Certain trace elements, such as copper, can
promote the production of melanin. Therefore, after laser surgery,
you should avoid eating foods containing copper and B vitamins, eat
less spicy foods, and eat more foods rich in vitamin C and vitamin
A. For example, eat more fruits, vegetables, and foods rich in
trace elements such as iron and zinc, such as lean meat, fish,
beans, Chinese cabbage, radishes, etc., and pay attention to
drinking more water. to promote skin repair.
