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.

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.
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.
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.
The whitening effect is not permanent.
Through laser treatment, good whitening effect can be achieved in most cases, but it can only last for about 3 years. With the passage of time, skin aging, pigment accumulation, skin will still have the problem of pigment deposition.
