When you’re at the stage of considering a particular treatment center or clinic, be sure to ask questions about which type of laser hair removal equipment they have and which machines you will actually be treated with.
Obviously the more state of the art the better. If their equipment is 20 years old, run a mile because equipment is constantly improving and if a clinic is not reinvesting in new technology then you are not getting the best results that could be achieved for your time and money. While these machines cost tens of thousands of dollars and clinics can’t constantly change them, that is not your problem and you do want to find a clinic which uses the latest and best.
Also remember that different types of equipment are suitable for different skin and hair types. When you go for your initial consultation ask why they recommend a particular piece of equipment for you over others that they may have. If they have only one type of laser equipment ask why they chose it and whether it is the best one for you.
The different types of laser equipment which you might encounter at clinics are:-
- The Ruby Laser is a 694 nm wavelength machine. (Also see brand names Epilaser, Rubystar and Palomar E2000). This was the first laser hair removal system used commercially and has been extensively tested. The light waves are very selectively absorbed by melanin (the pigment in the hair and skin). It causes selective damage to hair follicles, minimising injury to the skin. There is a 2 second period between each laser pulse designed to allow the skin to cool down and cause less injury and pain. This type of laser also only works on light skin colors
- The Alexandrite Laser Machine – This machine has a 755nm wavelength and works in a similar way to the Ruby laser. It is also only suitable for treating very white skin. It appears under the brand names of GentleLASE, Apogee and EpiTouchPlus.
- The Nd: Yag (1064 nm wavelength) laser which appears also under brand names CoolGlide, Medilite IV, Varia, Athos, Lyra and Image is meant to be capable of treating all skin colors however the evidence is still lacking about whether long term hair removal can be achieved for everyone. It was not designed specifically for hair removal and is more often used for removing tattoos. It must be used with a carbon lotion to effect hair removal and there is the difficulty of getting the lotion to penetrate to the follicles. If it doesn’t skin damage can occur according to the British Association of Cosmetic Doctors. It appears this is not the safest option
- The Diode laser (800 nm or 810 nm wavelength). There are lots of brand names for this type of laser including SLP 1000, FI Diode, Light Sheer, MeDioStar, LaserLite, Epistar and Apex 800. This kind of laser penetrates further into the skin than Ruby and Alexandrite lasers and may be used to treat darker skin although tests are still ongoing as to how effective they are at long term hair removal.
- Intense Pulsed Light (IPL) laser also appears under brand names Ultimate Light, EpilLight, PhotoDerm, Quantum, AcuLight or Vasculight. These type of lasers can safely treat all skin colors as there are many parameters on the machine which can be adjusted by a trained operator to effect hair removal in a more personalized way. See IPL hair removal for more details.
Which laser hair removal equipment will work best for you?
Unfortunately the FDA only approves systems as being safe and does not compare how effective one system is over another. And with most of the machines tests are ongoing regarding how permanent hair removal actually is. So you are left with requesting the evidence from the clinics you are thinking of using about their particular system or researching on the web where you may be fed stories put about by the manufacturers. By the far the best is personal recommendation of laser hair removal equipment from someone who has had success with it and has similar hair and coloring to you. Failing that get as much information about any particular machine as you can from independent medical websites.
