Laser hair removal is based on the principle of selective photothermal dynamics. By reasonably adjusting the laser wavelength and energy pulse width, the laser can pass through the surface of the skin to the root hair follicle of the hair. The light energy is absorbed and transformed into heat energy that destroys the hair follicle tissue, so as to make the hair lose the regeneration ability without damaging the surrounding tissue and slight pain.
1、 Top five laser hair removal problems
- Does laser hair removal affect perspiration?
Some netizens will ask, laser hair removal is done by destroying hair follicles, so will laser hair removal affect perspiration? Experts explained: sweat is not discharged from hair follicles. It exudes from the skin surface through sweat glands, which has no direct relationship with hair follicles. Therefore, beauty seekers do not have to worry about whether laser hair removal will affect perspiration.
- Does laser depilation have radiation?
Laser, when we first hear the word, always associate it with radiation. Does laser depilation have radiation? Experts said that the laser is not a radiation substance. It belongs to a laser light source. It destroys hair follicles through the action of light and heat to achieve the purpose of hair removal. Radiation generally comes from some kind of material or electromagnetic wave. Electromagnetic wave and laser are not the same thing. Those seeking beauty should not go into misunderstanding.
- Can laser depilation burn the skin?
Since the laser is a kind of thermal light source, improper operation or unqualified laser instrument may burn the skin. If you choose a large plastic surgery hospital for laser hair removal, this situation can be avoided. First of all, large plastic surgery hospitals have an authoritative team of doctors who are skilled in laser hair removal. Thirdly, large plastic surgery hospitals have relatively high-end hair removal instruments, such as lecher, freezing point hair removal, etc. these hair removal instruments have advanced cold light source technology. During the treatment process, they will not burn the skin, but also intelligently control the laser temperature, so that beauty seekers can carry out laser hair removal in a comfortable and painless condition.
- Laser hair removal season?
Laser hair removal is seasonal, because it has no wound and does not need recovery period, so it can be treated in spring, summer, autumn and winter. However, depilation experts suggest that you choose the spring and autumn season for laser depilation, because laser depilation needs to be carried out 3 ~ 5 times to achieve the effect of permanent depilation. If you choose the spring and autumn season for depilation, you can wear suspender skirts without fear in summer.
- How painful is laser depilation?
Laser hair removal is a hair removal method with less pain among all hair removal methods. The results of many clinical trials show that most patients only feel “bounced by a rubber band”. Laser depilation will cool the skin at the same time. There are many ways and principles of cooling, but they are all at a temperature of about 4 degrees Celsius. The freezing point depilation publicized by many plastic surgery hospitals makes you no longer feel pain. In fact, they are far away from 0 degrees, because under the action of laser heat, several degrees of contact makes people feel ice compress. In addition, because everyone’s physical condition is different, they feel different about pain. Before laser hair removal, there will be a “irradiation test” stage to determine the patient’s pain.
