How to choose a hair removal device? What does the number of flashes mean?

Nowadays, more and more people like to use hair removal devices to remove hair at home. There are many easy-to-use home hair removal devices on the market. When buying, try to choose a hair removal device from a big brand with a good reputation.

1. Choose a hair removal device that meets the appearance and craftsmanship standards

Precision appearance mold design is the primary factor in testing safety. Some hair removal devices will have large cracks when pinched by hand, and cannot pass the drop test, resulting in high-voltage leakage and light leakage hazards during use. It is recommended that girls should not use hair removal devices with safety hazards.

2. Choose a hair removal device with high energy density

Energy density (the amount of energy per square centimeter) is an important indicator of hair removal effectiveness. The higher the energy density, the more effective the hair removal and the longer the effect. However, high energy is more destructive to hair follicles, more likely to cause adverse skin reactions, and more painful.

3. Choose a hair removal device with a higher wavelength

Generally speaking, the higher the minimum wavelength of a home-use photon hair removal device, the safer it is, especially for dark skin. To ensure safety, the first thing to do is to avoid photon energy with shorter wavelengths. Too short wavelengths have insufficient penetration and cannot reach the hair bulge or hair bulb for treatment.

4. Choose a hair removal device with a lamp head area of ​​more than 3cm

The larger the lamp head area, the more convenient and faster it is to use. However, the larger the lamp head of a general IPL hair removal device, the lower the energy density, so you can't just look at the light area, be careful of low energy density. If you buy an IPL, it is recommended to buy one that is more than 3cm, which should be quite fast to use. For example, Silk'nSensepil has a large light outlet, but a very low energy density. The laser has a small light outlet, but a high energy density.

5. Choose a hair removal device with more lamp heads

The number of times the lamp head is used is related to the energy level used. The higher the energy level, the fewer times the lamp head is used, and the lower the energy level, the more times the lamp head is used. Because the lamp tube and capacitor configuration have a certain tolerance limit, the loss of high-energy lamps is greater than that of low-energy lamps, and the number of times is less. For personal use, if the lamp head is more than 3cm, buy a 10w lamp and it can be used for more than 3 years, which is probably enough for you to remove hair for many years.

6. Choose a hair removal device with a higher light frequency

Many hair removal devices now have the function of continuous light emission. The light emission frequency is the time interval between two light emission. The shorter the time, the faster the treatment. However, you cannot just look at the frequency. Generally, if the total energy released by the device in a single shot is higher, the light emission will be slower. And the higher the selected energy level, the slower the light emission will be.

7. Choose a hair removal device that is FDA certified

Hair removal devices are not cheap. It is not recommended for girls to buy detachable hair removal devices, because detachable hair removal devices are prone to poor contact, high voltage leakage, light leakage, and damage to the skin. It is best to use FDA-certified hair removal devices, because the US FDA is an international medical review authority, authorized by the US Congress, and the highest law enforcement agency specializing in food and drug management. Home hair removal devices certified by it are more guaranteed in quality, so when selling hair removal devices on Taobao, FDA-certified hair removal devices should be preferred. For example, TriaLaser, Smooth skin, and Panasonic ES-WH93 hair removal devices are all FDA-certified, which will make people feel more at ease when using them.

The number of flashes of a hair removal device actually refers to the service life of the hair removal device. Hair removal devices mainly rely on the instantaneous emission energy of lasers and photons to affect hair follicles to work, so hair removal devices that cannot flash cannot be used. Therefore, the number of flashes of a hair removal device directly indicates the life of the hair removal device.

The hair removal devices with the highest number of flashes are Silk pro (50 million times), Silk'n AS102275A (400,000 times), Silk'n Infinity (400,000 times), and Silk'n Jewel (400,000 times). In addition, the British version of Iluminage Touch hair removal device has also reached 300,000 flashes, and it also has a replacement head with 300,000 flashes. It can be said that it is also a commonly used hair removal device with a particularly impressive number of flashes and a relatively long life.

Step 1: Shave the surface hair 1-2 days before use. Ladies should use a razor to remove the surface hair 1-2 days before using silk'ninfinity. Because after 2-3 days, a little stubble will grow, usually around 0.1mm, which is the best time to use it. It is also best not to apply any products on the skin before using the silk'n hair removal device, and keep the skin dry. Otherwise, it is easy to damage the skin color sensor lamp.

Step 2: Assemble the plug and connect the power cord. Since the power plug of the silk'n hair removal device is separate from the hair removal device, girls need to assemble the power plug and connect the power cord before using it, and then turn on the switch.

Step 3: Press the power button to adjust the gear. Then girls can choose the appropriate gear to operate. It is recommended for novice girls to start from the first gear.

Step 4: Aim at the hair-bearing area for hair removal. After adjusting silk'n to the appropriate gear, girls can aim at the hair-bearing area for hair removal. It should be noted that the light outlet should be close to the hair-bearing area when girls use it, otherwise the light may not come out.
