It seems that the more I talk and research about lasers the more I get confused…
I have a question…
I heard there are two different lasers, the one with the red light and another one with a green light… is this true? What is the difference?
-Man this is confussing!!!
Thanks! </blockquote><font size=“2” face=“Verdana, Helvetica, sans-serif”>Valerie,
Before you buy a laser (or get treatments yourself), you should spend some serious time researching LHR (including the history of laser hair removal . . . it’s actually not as “tested” a technology as laser manufacturers might want you to believe, although new clinical studies on LHR are going on as we speak!).
There are many different kinds of lasers . . . ruby, diode, IPL (not techincally a laser), and many others. And different implementations of each kind of laser (these are the different manfacturers and models).
I don’t know what the red and green you’re talking about . . . but I’m sure that different lasers might have different visible colors (i.e. maybe the lasers at the lower end of the frequency spectrum are closer to red because they have longer wavelengths, while lasers at the higher end of the frequency spectrum appear closer to green or blue because they have shorter wavelengths, but that’s just a guess on my part). So that’s probably what you have heard about. If someone knows more about this they should correct me. I am not a physicist.
But it all comes down to clinical performance of different machines (there are clinical studies done on this, and manufacturer/model DOES matter), practitioner skill (it’s not a simple point and shoot thing, a laser in the wrong hands can quite easily cause someone to go blind or worse), and consumer experiences (which are usually are a result of the combination of the machine and the practitioner).
Before you go buy a machine I would advise doing some SERIOUS RESEARCH.
I’m just a consumer, but I’ve spent more than 100 hours so far researching laser hair removal. I’ve had 3 treatments using the LightSheer XC on my face (I’m a type IV on the Fitzpatrick scale, and my practitioner has been fairly agressive with the fluences considering how dark my skin is). You can read my experiences by doing a search for my user name or member number.
There are a LOT of scams and shams out there . . . Lots of unscrupulous people that prey on those that don’t do their research.
This forum (and Andrea’s other site, hairfacts.com) are a great place to start.
Be careful out there. Cut once, measure twice.
