What is laser hair removal? Laser hair removal is based on the principle of selective photothermodynamics, through reasonable adjustment of laser wavelength energy pulse width, the laser can cross the skin surface to reach the root of the hair follicle, the light energy is absorbed and converted into heat energy to destroy the hair follicle tissue, thus making the hair lose the ability to regenerate while possibly damaging the surrounding tissue, the stinging sensation is slight technology. Laser hair removal is a safe, fast and long-lasting hair removal technique. What do I need to know before laser hair removal? Laser hair removal is not perfect as it is best suited for people with light skin tones and dark hair, the treatment is targeted at “dark pigments”, if you have dark skin tones the laser will destroy the skin pigments together and cause white or dark spots, which often take months to recover gradually.

In most clinical cases, the average energy density used is just 10-20J/cm2 to remove hair efficiently, thus avoiding possible medical risks such as burns from occurring. Influencing factors: 1, different equipment laser hair removal effect is also different from the equipment, different treatment equipment in terms of the effect is a certain difference, the laser light source on the laser hair removal effect is a great influence, that is, some laser light source intensity is relatively large instrument, its treatment effect will be better than those light source intensity of small instruments. 2, physical differences also affect the effect of laser hair removal Everyone’s physique is different, and the thickness of hair, growth capacity is also different, the effect of hair removal is also different, so different individuals adopt the same hair removal method, some sensitive people, they may be able to remove all at once, while some other non-sensitive people, may have to take off a number of times to achieve the point effect. 3, skin and hair color differences lead to different laser hair removal effect Different skin color and hair color, treatment will also have some differences, because the laser treatment is extraordinarily selective, it is based on the pigmentation of the skin to determine the situation, that is, different parts of the hair follicle about the laser hair removal response is different, in the same individual, different parts of the hair removal effect is also different. As the pigmentation in different parts is also different. 4.The doctor’s experience determines the effect of laser hair removal The doctor’s experience is also crucial here, because an experienced doctor can correctly grasp the direction of your hair removal, as well as the indications or contraindications of hair removal, and can adjust the treatment plan in time to solve some conditions that occur suddenly during the treatment process.
