Laser hair removal device and photon hair removal device which is better
June 17,2022
Laser hair removal is to use a hair removal instrument to emit a strong pulse beam, which acts on the root of the hair follicle, and uses its instantaneous blasting thermal energy to destroy the activity of the hair follicle so that the hair will no longer grow and achieve a permanent hair removal effect. Because the laser has strong photothermal selectivity, the laser of a specific wavelength can only be absorbed by the corresponding pigment cells, so there is no damage to the surrounding normal skin, which is a safe and fast method.
The effect of laser hair removal is good, but there is pain, which is unacceptable to many people, so how to choose a hair removal device that suits you?
Hair removal devices are divided into laser hair removal devices and photon hair removal devices. No matter which hair removal device, users care about:
1. Is the effect good?
2. Does it hurt when using it?
3. Is it safe to use Ann?
4. Is the price within your ability?
1. Hair removal effect
The hair removal device uses the energy generated by light and heat to destroy the hair follicle to achieve the hair removal effect. Therefore, the key to the hair removal effect is the light heat energy. The greater the energy, the greater the damage to the hair follicle, and the better the hair removal effect.
2. Pain
The energy of laser hair removal devices is above 20J, and the energy of photon hair removal devices is about 3J to 10J. Compared with laser, the energy is higher to photons. The higher the energy, the more pain.
3. Security
The hair removal device uses photothermal hair removal, and the importance of light is self-evident. The wavelength of light is divided into lengths (also called wavelengths). Too short light cannot reach the hair follicle, and the light and heat energy will be absorbed by the melanin on the surface of the skin, causing damage to the skin. Therefore, the safety of the hair removal device depends on the wavelength.
A summary of the filter colors and corresponding wavelengths on the market, you can refer to (applicable to most brands).
No color filter (440nm)
The green color filter (490nm)
The yellow color filter (540nm)
The orange color filter (570nm)
The red color filter (590nm)
The crimson color filter (650nm)
Because wavelengths above 550nm are safe, photon hair removal devices with a yellow color filter or above are recommended.
4. Price
Laser hair removal is generally a large-scale instrument in beauty salons. It is charged according to the part, and it costs thousands of yuan each time. Photon hair removal instruments are generally used for home use, suitable for the whole body, and the price is 200-2000 yuan. It is purchased once and used for life.
