Erbium YAG Laser 2940nm (scar removal beauty apparatus)

D. When the Erbium laser and organizational role, there are three obvious heating and organizations related to the degree of organizational changes:
D-1. Stripping of vaporization: the role of the Organization of the laser, will enable the water in cells and organizations vaporization charring removal
D-2. Solidified layer: laser direct role in the organization of the Below are the irreversible degeneration of the solidification, a tissue necrosis.
D-3. Heating layer: the bottom is non-reversible bad heating layer, the dermis layer of the heating temperature reached   55-62, It can cause collagen contraction, regeneration and reconstruction. In order to achieve a satisfactory clinical results should be stripping vaporization to the dermis layer of shallow (no more than mesh layer, otherwise they will be left scars) solidification of the more narrow as possible, while heating the dermis layer must reach a certain temperature.

C-1 It can be used epidermis and dermis organizations to give priority to absorb the laser wavelength, cuticle skin thickness of about 15-20 microns, the water content of 30%; cuticle layers below the skin thickness of about 100 microns, 70% moisture content, Dermis layer thickness of about 1,000-2,000 micron, 70% moisture content. Epidermis and dermis contains a lot of water into the erbium laser target tissue.
C-2 Laser irradiation time must be less than the skin of the relaxation time of 1 ms.
C-3 The need to transfer sufficient energy from the epidermis and dermis shallow vaporization stripping.

C. Laser grinding to achieve safe, effective and must meet the selective effect of light and heat:

b. Dermal collagen remodeling, laser generated heat on the role of leather that will produce a contraction of the skin so that the relaxation was tighten the skin fold, which is due to thermal effects caused by the contraction of collagen results, I collagen Fiber in 55-62 at the rapid contraction, length can be reduced 60 percent. This will allow the healing of wounds in the process of new collagen to shorten the collagen fibers for the configuration, a new organizational structure to bear to-aging skin and wrinkles repair purposes.

3. therapy of Er:YAG Treatment  

Er:YAG laser can produce good water absorption of infrared 2940nm, using less than 250us pulse duration, Er: YAG laser each with more exposure to the organization, Er: YAG laser emission wavelength of 2940nm and the main water absorption Match the peak, the water absorption of carbon dioxide laser to 10 times, Er:YAG laser can let skin organization become thinner than CO2 laser, It can only penetrate the skin moist a few microns in depth, their skin in a time of relaxation 1-5ms, the extent of the damage stranded heat also very light, not vaporization of the Organization of the solidification of a thin layer, bleeding only needle size.

b. Erbium:YAG Laser

Generally speaking, the first laser, the skin was white bubbly, this kind of change that cells within the vaporization of water, leaving dry protein debris, salt to the dry debris, the apparent shrinkage of the skin, The skin was pale yellow, these features such as mouth-thick skin more obvious. Upper eyelid skin thinner and other parts have not significantly shrink the Organization more than three times the apparent turn yellow radiation, visible to those with a tawny degeneration of dehydration protein substances, these substances on behalf of the dermis layer mesh degeneration of collagen protein, after further Will now charring and thermal diffusion, leading to necrosis.

Thermal effect is the clinical application of the laser means a major role in the organization when the thermal effects on the surface, it will absorb a length in the direct heating, heat conduction through the heat relaxation to the surrounding tissue, was not conductive to the neighbouring organizations Near the surface can heat of vaporization or remove organizations. Removal organizations depend on the rate of laser energy in the organization of the aggregation. The higher the laser power, water vaporization and organizations removal faster, and minimize damage to the thermal cured net organizations than the speed of heat conduction below the surrounding tissue faster, which ensure that solidified the role confined to the laser absorption within the length.

2. Characteristic

It is superposition about the wavelength of 2940nm Er:YAG laser and the line of the water absorb. It is very famous be using in the surgical operation field. It is the known the best absorbed water (>3000cm) in the laser field. It is a good assistant of the doctor.
