OK - I'm probably going to get blasted for asking about this machine... but I'm asking anyway!
Has anyone purchased this or is it brand new to market?
Claims to be a diode laser using a 808nm wavelength... similar to the Rio I think?
Would this wavelength of diode laser have any chance of permanently reducing hair in ideal circumstances (light skin, dark coarse hair)?
Just asking....

The problem with your question is that effectiveness is not determined simply by the wavelength. Diodes have 810nm wavelength, but they're not all the same. Tria is a home diode and LightSheer is a professional diode. Tria won't give you permanent results due to the high pulse width of 600ms vs LightSheer pulse of 10-50ms (used on average).

They won't make a home machine as powerful as a professional machine. It's not safe.

Just curious: Why is it that longer pulse would be less efficient that shorter one? I guess Tria has lower energy output and thus has to use longer pulse to be able to deliver enough energy to the target. But how does it make it less effective?

I got this for my boyfriend, who is extremely hairy and would't go to a salon for that kind of laser removal. He's Italian so he has an olive type skin tone (not dark) and dark brown hair. We've had xemos for 3 months and its worked out really well. Because hes so hairy each treatment took a while. Now the hair is almost gone and im just going over bits that we missed on previous treatments. - weve done a total of 7 treatment so far..And the hair that was removed has not come back, or not that i can tell, i havent been counting lol.--I dont think it hurts him much but the laser does burn the hair. its really cool to watch it. it seriously works. I would recommend it. and i would use it but im virtually hairless and the hair that i do have it very light blonde. have fun removing your hair!!

Why is it hard to find a phone number to contact the maker of this Xemos? Why is there No Company Address listed either? Why do they seem to expect you to request service or returns via email?

Why does michaelrip have only one post and is her post so blatantly positive? Nice try though.

Yes, that's a blatant self-promotion.

Pertti, please read the FAQs at the link below. To answer your question, there are 3 variables that matter when setting the settings - joules, pulse, and spot size. All of these have to align just perfectly to kill the hair permanently. So even on professional machines, it can be hard to achieve these results if this is not done right.

Pulse width is VERY important. It's been obvious now through 10+ years of treatments. A certain amount of energy with a certain speed needs to be delivered to kill the hair permanently. And high pulse doesn't allow for that.

My friend picked one up a few weeks ago. She just started, but thinks it's working pretty good. I'll keep you posted of her results

You can't know whether it's working if you just started. You need to give it 9-12 months of use and then stop for at least 4-6 months. If you don't do that, shaving would seem permanent too.

I guess I'll let you know in a year then. hehe
