The Diolaze is a Diode laser made by Invasix (International) aka Inmode (USA). The Diolaze is one of the larger spot sizes for diode laser which makes treatments with it fairly quick and efficient. The Diolaze has the advantage of having a large spot size (this means your treatments will be relatively quicker).
In addition, it offers cooling before, during and after the laser treatment, which dramatically reduces the amount of heat created during the procedure. Heat does not make the laser more effective (fluence and the wavelength directed toward the area do) but can make the procedure much more uncomfortable.
The science behind this is that unmyelinated fibers (type C) pain fibers transmit the heat sensation as pain. Cooling the area can prevent those fibers from discharging. By pre cooling the nerve fibers, the nerve fibers are less likely to fire making the procedure much more comfortable. Cooling during the laser as well as after helps prevent the pain fibers from discharging.
One limitation of some laser systems is that patients will experience pain during the procedure forcing the laser to be used at lower energy (fluences) which can lead to less effective laser hair removal. By making the laser hair removal procedure much more comfortable, patients will be able to tolerate higher fluences and have a more effective end result.
Can the Diolaze be used on all skin types?
The Diolaze has the same limitations as any other Diode laser which means it is effective for most skin types including Fitzpatrick 1-5. The Alexandrite laser is effective for skin types 1-3 while the Nd:YAG is best for skin types 4-6.
How does the Diolaze make its treatments more comfortable?
3 seconds of superior cooling – comfort and safety- Post parallel and pre cooling. Highest pulse repetition rate at all settings improves speed.
Does the Diolaze laser hurt?
Every patient’s definition of pain varies from patient to patient. In the lasers our office tested, we found it to be the most comfortable laser due to its cooling system incorporated.
How does the Diolaze compare to other Diode lasers?
Diode lasers are dependent on delivering enough energy to the hair without creating enough heat to make the procedure both effective and safe. Two competitors on the market and the
Two largest current spot sizes are the Vectus and the Duet from Lightsheer. One issue with the larger spot sizes is that the fluence from both of these lasers is limited to 20 J/cm2 on the Vectus and 15 J/cm2 on the Duet from Lightsheer. This means that the first few treatments patients may note some effectiveness. However, as the hairs become finer, the larger spot size will not be as effective. The reason for this is that finer hairs require larger fluences. The optics on the larger laser spot sizes changes the physics of laser hair removal and may require less fluence. Many times offices are then forced to use the smaller spot size on each laser for final treatments (often times treatment 4-6). The smaller spot size on both the Vectus and Duet do have higher fluences, however it will take longer for this procedure to be performed since the spot is quite small. The Diolaze has a slightly smaller spot size than the large handpiece on the Vectus and the Duet, however, it has a higher fluence. This means that the Diolaze will be slightly slower on treatments 1-3, however on subsequent treatments the Diolaze has the theoretic advantage of higher fluences (up to 60 J/cm2) versus either the Vectus and Lightsheer large handpieces. If comparing the Diolaze versus the Duet or Vectus smaller spot size, the Diolaze will be much faster. The main advantage, other than efficacy, of the Diolaze is comfort. The Vectus does not use a cooling plate but does used a sapphire contact cooling making the procedure tolerable. The Duet smaller handpiece also has a cooling contact tip. The Diolaze uses a 2 degree centigrade chiller plate plus the cooling contact. This allows for pre cooling, cooling, and post laser cooling. In our experience with our patients the have found this to be the most comfortable laser we tested.
