First good news when you unpack the Lumea, everything is very simple. I expected 30 pages of instructions, it is not. Two clear pages, small drawings and color guide skin / hair to choose its intensity. Only negative point, a small pouch would still be significant.
A small test on the shoulder and then after 24 hours to see if there are no bad reaction, one can attack.
Another disadvantage light, it can be used as power is on but it is not essential to be in the bathroom as hair removal is done after shaving.
It is indeed essential to be impeccably shaved because when going on a badly cut hair, it gives off a slight odor of grilled rather unpleasant hair. However on the shaved skin, nothing, at most a small feeling hot but not any pain, even at maximum intensity.
All this takes a little time, it's a bit irritating because after each flash you need to move the device and the treated area is really not great. Between each flash there are two three seconds before recharging it. So I put a good twenty minutes to do the whole area (both arms above shoulders +). Then it takes several days to see if there is a result.
A priori, it works. But be aware that the hairs are not all in the same state at the time of the flash and the pulsed light is only effective on hair that are at some stage. Other hair, even clean-shaven, are not affected and therefore repel normally. 15 days later so you have to start all over again but after each one there is really obvious decrease in the number of hairs that grow back (after two passes, there were already small areas totally hairless).
According to the manual, it takes two months for all the hairs are destroyed. I'm on my third set (1 month and a half so) and I do not have much hair that grows back. This seems to work well.
