There are a total of five types of Laser products available for hair reduction :
Intense Pulsed Light (IPL) :
Intense Pulsed Light (IPL)
Common Names: PhotoDerm, EpiLight, Quantum, Aculight, Vasculight
Probably the most commonly used laser for hair removal. IPL delivers a wide range of light including the infrared spectrum. There are many systems that fall into this category; Aculight and Quantum are systems that are more user-friendly and commonly used by novice operators. The limitations which make these systems easier to use make these machines less effective. Up to 8-10 treatments are needed for permanent hair reduction in a span of 2-8 weeks using IPL treatment.
IPL is gentle and usually painless, which means it can be used virtually anywhere on the body, making it a good choice for those with sensitive skin and a low threshold for pain. It works best on those with dark hair and fair skin but can be used on all skin types.
IPL isn’t recommended for white or blond hair.
Diode Laser :
Common Names: SLP, F1 Diode, LightSheer, MeDioStar, SopranoXL, LaserLite, Epistar, Apex
The Diode laser is hugely popular and fairly new. It has a long wavelength, which allows deeper penetration of light into the follicle and less damage to the skin itself. There is also a low risk for discoloration. Keep in mind, because this laser is fairly new to the game, there is less experience and less long-term data in evaluating how successful this laser is for hair removal.
This laser is good on most skin colors but performs best on light to medium skin tones.
The procedure is quick with minimal side effects, but you may need several sessions. Because it features newer technology, the longevity of results cannot yet be accurately assessed.
Common Names: CoolGlide, Medlite IV, Varia, Athos, Lyra, Sciton Profile, Image
Cutera, Cynosure Elite, Candela, GentleYAG
The Nd: Yag units are often used to remove tattoos and hyper-pigmentation, but can be used for hair removal as well. The longer wavelength allows deeper penetration into the skin without discoloration, but you may require more treatments than other lasers.
This is the preferred method for dark skin to minimize risks of post-treatment blistering and pigmentary change, though it can be used on the full range of skin color.
Unfortunately, these lasers are less effective on fine hair and tend to be painful.
Common Names: Candela, GentleLase, Cynosure Apogee, EpiTouch Plus
These lasers are the fastest lasers out there, which means you can cover more area in less time. Alexandrite lasers have a shorter wavelength which makes them well suited for light or olive colored skin. It has been proven most effective for fine, thin hairs that the other types of lasers have not been successful in eliminating.
The speed makes this a great option for those wanting to cover larger body parts, like legs and back.
Unfortunately, there is some discomfort involved and there is a significant risk for discoloration and burns in those with medium to dark skin.
Ruby laser :
Common Names: RubyStar and Palomar E2000
This is the oldest type of hair-removal laser and uses the shortest wavelength, which makes it very effective if your hair is lighter or finer. They are relatively painless, which make them good for sensitive skin.
Light or fine hair, light skin, sensitive skin.
Ruby lasers can cause pigment changes in those with anything but fair skin. They also cover a relatively smaller area than other lasers.
Where you go and who performs the procedure is critical because it plays a big role in the outcome. The same type of laser can vary depending on where you get it and who wields it. If the laser is an outdated model or a rental or not up to code or it was purchased from some questionable discount site you are at a greater risk of injury or getting a poor result.
