Hi, has anyone heard of this new home laser device?
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.
You said this laser cant eliminate hair, i thought all lasers never permanently remove hair just reduce it?? On a tanned/brown skin patient what would the settings be at if they were to go to a laser clinic? would it not be around 24-30 joules?
And also what difference does the spot size make? is it that the bigger it is the more faster larger areas can be treated?
Lasers can permanently remove hair if the circumstances are right.
-
your assumption is wrong. i don’t know where you go that. lasers CAN permanenly destroy hair. professional powerful machines that is, not this device. and on the right skin and hair type and at correct settings.
-
how fast an area can be treated is only a side benefit. larger spot size puts out more energy and reaches deeper into the follicle.

if you’re asking about joules on this little machine, it’s a useless question. if you read sslhr’s post carefully, he outlines how you would need at least 10 times as many joules on this machine to produce the effect that a professional diode like LightSheer would produce (so 25 joules on LightSheer which is needed at minimum for effectiveness would mean 250 on this thing), and that’s not taking into account the pulse and spot size issues. if you’re asking about joules on a professional machine, it’s more complicated than that especially for brown skin. You would need a Yag laser and settings are not equivalent among machines. It would depend on the machine used.
Guys… Why don´t you just shut up and let someone who has tried it give their opinion… If you don´t want to buy it… don´t! Anywayz… why are you so interested in talking terribly about a device you haven´t even tried ?!? Hmm… Geeee I wonder why…
And by the way Miss lagirl… a razor makes your hair come back “thicker” and in less than 2 days you gotta shave again…there´s a BIG difference…Have you ever shaved your legs?
Maybe its not permanent, but even if it´s long lasting and it put hair ( as sslhr says ) in a dormant state…it works for me!
Miss lagirl let me ask you something… why do they call it permanent hair removal? Why don´t they just call it…definitive? and also…why is it called now permanent hair REDUCTION?..As you are so instructed on lasers…maybe you can explain this to me and the guys!
considering the rudeness in your posts, i won’t repeat what has been stated on this forum for more than 5 years now in various threads AND in detail right above in this very thread (did you ignore everything stated above with the REASONS explained as to why it doesn’t work?). use the search feature at the top right and you’ll find the answers to your questions in other threads too.
while you’re at it, also search “shaving” (and do this elsewhere if you’d like as well) so you can learn why shaving DOESN’T make the hair any different. It’s an old wive’s tale.
I just thought I’d bump this thread back up to the top to see if anyone has gotten this yet. It’s my understanding that it’s been available in Japan since 2005, so hopefully by now it’s known whether or not it actually does anything. If anyone here can read Japanese, it’d be cool if you could summarize what’s being said. 
Darker skin types need YAG lasers, as mentioned above. However, the skin must not be tanned, when I say tanned I don’t mean natural colouring, I’m talking about sun tan. When the skin is exposed to UV light, the melanin particles become “excited”, thus making even light skin more prone to burning.
Hence why for the past year I haven’t ventured out into the sun. Even when I went to Lanserote I just stayed in the shade and crammed for my exams because my skin tans way to easily if I was out having fun in the sun, even with SPF30 or 40.

I’ve decided to take the plunge and try Tria when it comes out. I’ll let y’all know what happens. I gather from reading reviews of it that it does something(feels like a rubber band snapping and causes shedding). It’ll be interesting to see if the results are long term.
I was discussing this with my husband the other night and he made an interesting point when I said “how could something that costs $1000 work as well as something that normally costs $50,000.” He pointed out that professional equipment is always much more than the home version. Professional equipment has to withstand several hours a day, everyday usage. Granted, that doesn’t mean the Tria will actually work, though. We’ll see.
I wonder what kind of chrystal they are planning on using in this machine.
