Hi, has anyone heard of this new home laser device?

http://www.tria.co.uk

there are a ton of these devices. they're not really new. there are always plenty of desperate consumers willing to spend a few hundreds dollars to "cure" their problem. unfortunately, it's not that easy.

currently no home devices that are powerful enough to produce any permanent hair reduction. we would all be using one if there was. this site doesn't provide any specs on this unit and the reason is probably very simple - it emits very little power to cause any permanent damage to the follicle. this should also be obvious because there is a reason that the professional machines cost $50K and up and are not sold to consumers. they're not safe to operate or own without proper training and equipment. anything that is would have to be very "safe", i.e. ineffective. the "studies" the provide are meaningless. 60% removal 3 weeks post treatment? technically, you're supposed to see 100% removal 3 weeks after first treatment, except calling it "removal" is misleading in the first place. these studies were only conducted to test "safety" for home use, not effectiveness.

Andre, Andre, Andre! Please keep in mind that the power of heat in the right amount is needed to destroy all the necessary structures of the sturdy hair follicle below the skin. You have asked about several products for home use and none of them emit the energy/power that is needed to permanently destroy a hair. Go get real laser treatments from a qualified technician.

Removing hair permanently is not zip-zap easy or quick and all the bare naked ladies in these slick glossy's try to deceive good,hopeful people like yourself.

whats the min energy required to do damage to the hairs?

the spec is on here http://www.tria.co.uk/technicalspecifications.htm

Poster's sslhr or lagirl will have to answer this question as there are differences among each kind of laser that have been CLEARED by the FDA for hair removal.

Several wavelengths of laser energy are involved for effective hair removal. Pulsewidth is an important consideration. Spot size affects treatment. Repetition rate for heating an area matters. It takes more than joules/fluence to evaluate what laser may be effective on your skin and hair type.

It would be great if sslhr could get more technical with you after he reads the specifications of this particular product. I hope he will check in. I'm thinking 250 pulses is all you get for one charging and that is well below what you can get professionally speaking. I'm thinking that cleared home devices are all about safety more than effectiveness because you don't know who (child or an adult idiot)could get their hands on this gadget and do serious harm. Another clue is, no eye protection is needed. How powerful can this thing be with the an obnoxious sturdy structure like a hair?

10mm spot size even at max 24 joules on a diode is very low and will not kill your hair, especially at a pulse of 125-600. sorry. to give you something to compare, LightSheer diode that is actually effective is only effective at settings of at LEAST 25 joules and up, 12mm spot size, and has pulse range of 5-100ms (the lower the pulse, the more effective).

But do you think this would cause any reduction at all, doesnt really matter if its permanent?

If you would like to be the pioneer and go forward and buy this product, then you can tell us how well it works. It may be just what you are looking for.

I don't have the time, the money, or the desire to buy every gimmick out there (there are literally hundreds) and try it out on myself. It might cause some shedding, it might not. Who knows. I would definitely read your report if you decide to try it though. Then, we can post it for others who come looking for an easy but not permanent solution. If you're not looking for a permanent solution, I don't see why it's worth it to pay money for this instead of a wax or a good razor.

This is a diode laser. The best way to understand a diode (the same laser in a laser pointer) is to think of having thousands of laser pointers bundled together all pointing at the same direction. When you turn them on they are on and pumping out photons and when you turn them off, they are all off.

Now each manufacturer limits the number of diodes in the bundle due to cost and design issues. So the way to make up for this design limitation is to leave them on longer so they pump out more photons. This is different from the other type of laser called a pump chamber laser. Now this laser, which is pretty low powered in the sense that it doesn't have many diodes in the array (that bundle of laser pointers) only reaches 24 joules. It could actually reach higher joules by leaving it on longer.

To compare this laser to the LightSheer, another diode that is used for hair removal, This laser pumps out 1 joule of energy every 20 or so milliseconds, while the Lightsheer pumps out 1 joule every 2 ms. So basically this laser is 1/10th the power of the Lightsheer before we even begin to discuss the spot size difference.

Now can this system eliminate hair? No, it is not powerful enough.

Could it temporarily put hair into a dormant state so that it doesn't grow? It might and I am sure that in some it does. The energy necessary to put a hair into a temporary dormant state is much less than the energy necessary to kill that hair.
