I rather call this device a hair epilator a reducer: indeed, before using on the body (all areas outside face), it is necessary to shave or pluck. It does not remove hair in reality, it simply slows regrowth. Knowing that the results are visible only after 4 weeks and after 10 to 12 treatments of skin, I can not judge its effectiveness in hair reduction. So I'll add a comment to further few weeks. There are many indications cons concerning the use of this product: recent chemotherapy or radiation therapy, tan or very dark skin (black people), epilepsy, pregnancy or breastfeeding, major skin problem that required medical treatment. As for your pigmentation, it is the device itself evaluates and adapts automatically. All precautions and usage tips are very well detailed in the manual which has a component in French. But for all those who are able to use it, it is a great comfort of use: when the pulses, it feels only very slight stinging, even on maximum power, and a small clearance heat, but nothing painful. If you are too far away the gun of your skin, the pulse is not triggered because the device is designed not to be triggered in a vacuum, so as not to risk a flash towards the eyes. Moreover, it is not noisy at all: it emits only a slight hum that looks like the blast of a hair dryer, but much less strong! Side use one word: extremely simple! With a very comfortable grip, it presents very few and simple commands. It does not heat up in the hands during use.
