Laser freckle removal generally uses the principle of selective photothermal action. Pigment particles in pigment-containing cells in skin lesions selectively absorb laser heat in a very short time, so that pigment cells and particles explode and disintegrate, and then slowly remove and metabolize human phagocytes. The whole process takes about 2~3 months.
Laser can solve different kinds of diseases, but different kinds of lasers are needed. This is because the laser is monochromatic, and one wavelength of the laser is particularly sensitive to a certain color, so it can be removed. If properly treated, laser freckle removal can achieve very good results.
Extended data:
Different pigment spots have different reactions to laser, some are suitable for laser treatment, and some have poor reactions to laser. Before choosing laser freckle, patients should go to a dermatologist to confirm the type of pigmented spots, the number of times they need treatment and the effect after treatment, and then decide whether to use laser freckle.
Laser freckle removal has an excellent effect on nevus OTA (black face), freckle, zygomatic spot (zygomatic brown-blue nevus), senile plaque and senile wart, and also has a good therapeutic effect on chloasma, coffee spot, pigmented nevus and spotted nevus.
However, pigmentation, melanosis and Becker's nevus have great individual differences in response to laser treatment, and the number of times they need treatment is not necessarily the same. You can do local trial laser treatment first.
