2, the principle of laser freckle.
The principle of laser speckle removal is that laser instruments produce high-intensity beams, and different types of lasers can produce different colors of light. Color is the key to treatment. Different colors of laser are absorbed by different colors of skin, and dye particles are decomposed and vaporized by laser energy, sealing blood vessels, and then the dye particles are absorbed by the body and excreted, and the pigment disappears. Because the laser of a certain wavelength is only absorbed by the pigment of the corresponding color. Only diseased cells can absorb specific laser, while normal skin tissue will not be damaged, so it will not leave scars. Advanced laser technology can also control the depth of laser reaching the skin, and adjustable pulse can minimize skin damage.

4. Side effects of laser whitening
(1) pigmentation
Pigmentation, also known as post-inflammatory pigmentation, is one of the common sequelae after laser whitening treatment, which is usually caused by careless sun protection, ultraviolet rays stimulating melanin secretion, or untimely anti-inflammatory and wound infection.
(2) Blister
Laser whitening is to promote pigment decomposition through photothermal effect, so as to achieve the purpose of whitening. If the instrument and energy are not properly selected, the light absorption of non-target tissue is too high, and the temperature of skin tissue is too high, forming scalding blisters. Small blisters can fade without leaving scars under the care of light energy conditioning cream and scald cream, but larger blisters will leave scars.
(3) Depigmentation
Depigmentation usually occurs in beauty projects such as laser freckle removal and laser Dot mole. During whitening treatment, due to excessive use of laser, melanin explodes excessively, pigment is too little, and the skin appears abnormal gray.
(4) Persistent erythema
Persistent erythema is also a common side effect. After laser whitening treatment, the skin will appear transient redness, but if it is not properly cared, the epidermis will be seriously damaged, and then persistent erythema will appear.
(5) Redness and pain
When using laser whitening treatment, there will be some pain, such as elastic skin, and people who are sensitive to pain need to apply anesthetic ointment. And because there will be a certain degree of redness and swelling after the operation, a few people's skin will be damaged and oozing blood.
