Is it time to take off the “hair pants” in winter? If you want to show perfect skin in summer, now you need to remove hair!
What is laser hair removal?
The laser is a single-wavelength, continuous beam of light with extremely small divergence and high energy. Laser hair removal is based on the theory of selective photothermal action. Through reasonable adjustment of light wavelength, energy, pulse width, etc., it acts on the melanin of hair follicles. The light energy is absorbed by melanin and converted into heat energy that destroys the hair follicle tissue, thereby causing the hair to lose regeneration. Ability to achieve the purpose of permanent hair removal without damaging surrounding tissues and having a slight sympathy.
Lasers commonly used for hair removal are:
Diode laser-wavelength 810nm
Ruby Laser-Wavelength 694nm
Alexandrite Laser-Wavelength 755nm
Garnet laser-wavelength 1064nm YAG
Strong pulsed light-wavelength 590nm-12nm
Diode laser is the first choice for laser hair removal
Diode laser hair removal is currently a very ideal laser hair removal method. Its wavelength is 810 nanometers, which is in the near-infrared region of the spectrum. It has good absorption of melanin, and it can penetrate into the deep layer of the dermis and subcutaneous fat tissue, acting on different parts and depths of hair follicles, causing the hair follicles to be heated and coagulated and necrotic, thereby effectively removing Hair of any part and depth of the human body can truly achieve the effect once and for all.
The advantages of diode hair removal: permanent hair removal, no skin damage, the most advanced, good curative effect, safety, large spot, large area hair removal, high efficiency, fast speed, no pain, etc.
Why does hair removal need multiple treatments?
1. Hair growth is cyclical, that is, it continuously circulates from the growth period to the regression period to the resting period and then to the growth period. This change in the growth cycle is a continuous process;
2. Hair in the growth period, the roots and bulbs of the hair contain a lot of melanin. After the melanin absorbs the energy of the laser, it can effectively destroy the hair follicles to achieve the purpose of hair removal;
3. In the telogen and anagen phase, there is little or no melanin in the roots and bulbs of the hair, and the laser cannot use the hair follicles, so the treatment at this time is ineffective for the hair. The degenerative period of hair is generally 2-4 weeks, and the resting period is generally 3-4 months.
Generally speaking, the laser only affects the hair in the growth period, that is to say, it only affects the part of the hair currently visible on the body surface. It has no effect on the hair in the resting period. There is an interval of 1 after each treatment. -1 and a half months, wait for the hair to grow out in the resting period, and then perform the second hair removal. Therefore, one treatment cannot solve the problem. Generally, 3-5 times of hair removal can reduce the hair by more than 90%, so it usually requires multiple treatments.
