The principle of laser hair removal is that light penetrates the skin and reaches the hair follicles, releasing energy to destroy the hair follicles. If the hair follicles are destroyed, the hair cannot grow, so laser hair removal is useful. The laser passes through the surface layer of the skin and reaches the hair follicle at the root of the hair. The melanin in our hair follicles and hair shafts selectively absorbs light energy. Under the circumstances, achieve the effect of hair removal.ipl hair removal at-home

 

  1. Advantages of laser hair removal

 

  1. Fast, the effect of freezing point laser hair removal is very fast, and the effect of hair removal can be achieved in a very short time, which will not affect the normal work and study of beauty lovers.

 

  1. Safety. Freezing point laser hair removal uses the selective photothermal principle of laser to act on hair follicles. Freezing point laser hair removal is very safe and does not damage the normal skin of beauty lovers.

 

  1. Skin rejuvenation, freezing point laser hair removal can also effectively promote the regeneration of collagen, making the parts of beauty lovers more firm, smooth and elastic after hair removal.

 

  1. The effect is good, the effect of freezing point laser hair removal is better and more effective than the traditional hair removal effect, and can achieve the effect of sexual hair removal.

 

How to choose a hair removal device that suits you? Although there are laser hair removal devices advertised on the market, in fact there are two types of hair removal devices: laser and photon.

 Laser hair removal

Laser (also known as Laser), photon (also known as IPL, colored light, intense pulsed light), no matter what kind of hair removal device, we need to know these three points:

 

  1. Is the hair removal effect good?

 

  1. How about the safety of hair removal?

 

  1. Is it convenient to use?

 

The hair removal device uses the energy generated by light and heat to destroy the hair follicles to achieve the hair removal effect, so the key to the hair removal effect is the light and heat energy. The greater the energy, the greater the damage to the hair follicles, and the better the hair removal effect. The energy of the laser hair removal device is above 20J, and the energy of the photon hair removal device is about 3J to 10J. The greater the energy, the stronger the pain. We need to choose the hair removal device according to our own conditions.

 

The hair removal device uses light and heat to remove hair. The wavelength of light is divided into lengths (also called wavelengths). Too short light cannot reach the hair follicles, and the light and heat energy will be absorbed by the melanin and hemoglobin on the surface of the skin, causing damage to the skin, so hair removal The key to the safety of the instrument is the wavelength. The laser hair removal instrument does not need to consider the wavelength, because it releases monochromatic and directional pure light, and the wavelength is fixed at 810nm. Studies have shown that wavelengths above 550nm are safe. The photon hair removal device needs to consider the wavelength, because it releases a broad-spectrum band of light, not a specific length, but a range, which is between 400nm and 1200nm. For this reason, the photon hair removal device will be equipped with a filter, which can cut off unnecessary wavelengths and only emit a certain wavelength in the band. The actual wavelength emitted by the hair removal device will be different if the color of the filter is different. Wavelengths above 550nm are safe, so photon hair removal devices with yellow filters or above are generally recommended.

The convenience of the hair removal device is closely related to the area of the lamp head and the flash frequency. The larger the area of the head lamp, the larger the skin area that can be covered, and the larger the range of hair removal in a single session; the light frequency refers to how often the light is emitted, and the speed of the light is fast. You don't have to wait half a day to light up every time you run out. Pay attention when purchasing: the lamp head area of laser hair removal instruments is generally small, less than 1cm, and the light output frequency is about 2s-2.5s. The lamp head area of the photon hair removal instrument is generally large, the area is about 2cm-5cm, and the light output frequency is about 1s-5s. Z is finally sharing two TIPS.

 

The hair removal device should consider whether to use it with a plug-in cable or charging. I recommend buying a plug-in model, because there will be a problem of power interruption when charging. The service life of the hair removal device does not require excessive attention. Because the life of the hair removal device refers to the number of flashes, it is generally impossible to use that number of times. The service life of the photon hair removal instrument is about 100,000 to 400,000 times. The service life of the laser hair removal instrument is 30 million to 50 million times. The main points of choosing a hair removal device are not complicated. To sum up: laser hair removal device: high safety, good hair removal effect, but very painful; in addition, the lamp head area is small, which belongs to point-to-point hair removal, which takes a long time. Photon hair removal device: the safety is inferior to that of laser, you should choose a model with a wavelength of 550nm or more; the energy density is low, it only damages the hair follicles, the hair removal effect is not as good as laser, but the pain is mild; the lamp head area is large, and the hair removal time is short.
