980nm diode laser is the best absorption spectrum of porphyrin vascular cells. The vascular cells absorb high-energy laser light with a wavelength of 980nm, coagulate, and finally dissipate. The laser can stimulate the growth of collagen in the dermis while treating blood vessels, increase the thickness and density of the epidermis, so that small blood vessels are no longer exposed, and the elasticity and resistance of the skin are also significantly enhanced. Laser system based on laser thermal action. Percutaneous irradiation (1 to 2 mm through the tissue) causes the tissue to be selectively absorbed by hemoglobin (hemoglobin is the main target of the laser).
Advantage:
1. Small side effects: no burning, swelling, scars;
2. Less treatment course: only one or two treatment courses;
3. Portable and dexterous design, convenient for treatment;
4. Better effect: the energy is well concentrated on the 0.5-3mm spot;
5. The size of the spot is adjustable: 0.5-3mm in diameter, which is convenient for the operator to treat.
The working principle
Based on the thermal effect of the laser, the 980nm semiconductor laser system is divided into four stages:
Laser light is converted into heat energy.
Heat is transferred to the walls of the container.
Thermochemical action on the tissue components of blood vessel walls.
The container wall is damaged.
Mainly used for vascular treatment:
1. Pigmented lesions: age spots, sunburn, pigmentation.
2. Treatment of vascular disease.
3. Spider vein/facial vein.
4. Remove red blood: various telangiectasias, cherry-shaped hemangioma, etc.
5. Skin protrusions: skin problems such as warts, moles, flat warts, compound moles, junctional moles, and fat granules.
