Hiya Jason N,
Well in answer to your question on the Lyra-i it’s a Nd:YAG Model, with a maximum of 10mm spot size and minimum pulse of 20 ms. This laser is typically used for vein removal, shaving bumps, facial wrinkles and then hair removal. (Taking into consideration that the GentleLASE has a set pulse of 3 ms [the lower the pulse the more power] and maximum spotsize of 18mm).
A direct quote from a manufacturer is “The flat beam profile consistently delivers energy in the therapeutic range to all targeted structures”. Therapeutic meaning not high power, compared to models such as the GentleLASE, Lightsheer, diode etc.
There have been studies showing that Lasers and IPL’s with 12mm spotsizes or below may actually not wield enough power to permanently remove hair, especially such tough ones as facial hairs. In conlusion this is not a particurally good model for hair removal, it is more designed for treating skin problems as those listed above.
In regards to your facial hair, be very careful with doing laser on your face, make sure you find someone with a lot of experience, preferably someone who specialises/has doen a lot of hair removal on male faces. If you run a search you can find a lot of posts from men who have done this and have had results that range from patchy to grid like. This is due to poor tecnique and not “overlapping” enough when using the laser.
The best lasers for you depend on your skin type, types I and II are usually the most ideal for GentleLASE although type III can do as well, but the practitioner will have to be careful with the level of power used.
Skin type IV and above should search for Nd:YAG’s (preferable ones with a bigger spot size than 12mm’s), for example the GentleYAG etc.
When preparing for laser hair removal, you should always shave the area so that the laser energy is not wasted on the hair above the skin, but it’s always useful to have a little stubble above the skin so that the laser and the technician can see the hair. Depending on your hair regrowth, shave your face the night before or however long you need to wait to get the equivalent of a 5 o clock shadow. Lasering a freshly shaved face will be more painful and can lead to post laser irritation.
Hope this has helped,
Benji
