Laser hair removal is based on the principle of selective photothermal action. By reasonably adjusting the wavelength, energy and pulse width of the laser, the laser can pass through the skin surface and reach the hair follicle at the hair root. Melanin in hair follicle and hair shaft selectively absorbs light energy, and the resulting thermal effect causes hair follicle necrosis, thus making hair lose its regeneration ability without damaging surrounding tissues, with slight pain. Because the process of hair follicle endothermic necrosis is irreversible, laser hair removal can achieve the effect of permanent hair removal. The cost of laser hair removal is about1000-2,000 yuan each time, and it takes about 3-5 treatments with an interval of 20-45 days.

MM who wants to do laser hair removal had better do it before the arrival of summer, or in autumn and winter, because laser hair removal usually takes three to five times, and it can't be done once, and it will grow after taking off once. Although it is not as thick as before, its hair is soft and its color is very light, it will still have a little impact. Do it once and do it again a month later. When you do it later, the treatment time will be much shorter, because a large part of your hair has been stripped!
