1, and the best wavelength is adopted for treatment: the laser can be selectively and fully absorbed by melanin, and the laser can effectively penetrate the skin to reach the hair follicle position. The role of laser is effectively reflected in the heat generated by melanin in hair follicles for hair removal.

2, the best hair removal effect, the required laser pulse time is related to the thickness of hair, the thicker the hair, the longer the required laser action time, and the ideal effect can be obtained without damaging the skin.

3. Laser hair removal treatment will not produce pigment precipitation on the skin surface after hair removal like traditional hair removal methods, because the skin absorbs less laser during laser hair removal treatment.

4. The use of cooling system can effectively protect the skin from laser burns during the whole process.

1. Hair can be divided into three periods, namely, growth period, regression period and static period. The energy emitted by the laser instrument can only destroy the hair follicle in the growing period, and has no obvious effect on the hair in the fading period and the rest period. Only when these hairs turn into growth period can laser play a role, so laser hair removal needs many treatments to achieve obvious results.

2. If the proportion of hair in a certain part is small, the number of treatments will increase. On the contrary, the number of treatments can be reduced.

3. Different hair growth cycles based on different parts have different treatment intervals. If the rest period of hair is relatively short, the interval can be as short as l months; The hair rest period of trunk and limbs is relatively long, so the treatment interval should be about 2 months, so you can easily enjoy the confidence brought by Lido silky skin.

4. If the hair follicle density in a certain part is too high, the laser energy should be appropriately reduced during treatment. algesthesia

Laser hair removal is a less painful hair removal method among all hair removal methods. Before laser hair removal, there will be a stage of "irradiation test" to determine the degree of pain of the patient. The results of many clinical trials show that most patients only feel "bounced by a rubber band". Laser hair removal can also cool the skin. There are many methods and principles of skin cooling, but all of them are at a temperature of about 4 degrees Celsius. Many plastic surgery hospitals promote freezing point hair removal to make you feel no longer painful. In fact, it is still far from 0, because under the action of laser heat, a few degrees of contact will make people feel iced.
