The photothermal effect means (laser generated) temperature (heat) has a series of influence on the organization, above a certain temperature by skin cell death induced by injury. Selective photothermolysis simply is greater than the tissue around the target area, the absorption of red laser contrast, bigger and better.
In the Department of Dermatology, the skin is the main target of chromophore melanin, hemoglobin and water, they are in a different wavelength of red laser have different absorption capacity, higher call absorption peak, because of the different peaks, convenient for doctors to selectively use different wave length of laser, both against the enemy again, don’t hurt people.
Have the basic knowledge of the above, is not difficult to understand why the red laser can be the treatment of vascular diseases, why can treat pigment disease, why can the laser to tattoo, laser hair removal can be why, these are selective photothermolysis + appropriate wavelength of laser light to.
Effect of wide spectrum red laser is very significant to eliminate inflammation, so some are progressive inflammatory acne can be considered to try this, those who leave acne subsided after the acne, or we say pigmentation, can also solve the light.4-5 a course with strong pulse interval of 3 weeks, 1 months.
