The device should not be used on tanned or dark skin. If you try it nevertheless, the skin color sensor prevents the function. Tattooed skin should not be treated because it can cause burns here.
The light pulse window to be placed directly on the skin, otherwise it emits no light pulse. It is recessed to prevent it has not direct contact with the skin, but you should not look directly at the flash of light in the application.
Between the first 4 treatments 2 weeks each should be, between the 5th-7th and optionally thereafter every 4 weeks.
Now to the application:
The hair must be shaved and not been treated with wax, the skin dry and without deodorant.
After switching on the device, it makes a noise like a quieter hairdryer.
There are 5 power levels with plus and minus adjusted, depending on body part should be tested, what level you need. If you feel nothing is testing to the next level.
When the light pulse window rests properly light up the left and right green lamps. Then you press the light pulse button and the device checks the skin color. Man a short warm feeling. The areas that you want to treat should be treated only once and do not overlap where possible. Therefore you push the unit best firmly so that it leaves an imprint.
Depending on the body part you take the big or small light impulse cartridge. The small is ideal for the facial area, where I tried it today. It is not painful and is going well. Now I have to wait, let's see if hair regrowth 2 weeks.
After treatment, the light pulse window must be cleaned with screen cleaner for example.
So far I can only say positive. The application is easy and leaves no trace.
