Laser hair removal can be done with three different types of devices: 755-Alexandrite, 810-Diode, 1064-Nd:YAG, and IPL. These are commonly referred to by either their wavelength or medium: 755, 810, 1064, and IPL, or Alex, Diode, YAG, and IPL.

Each wavelength is best suited for certain skin tones on the Fitzpatrick scale. The Fitzpatrick scale rates skin tones on a scale of one through six (I-VI). One is very light skin with fine hair much like a Norwegian. Two and three are your typical Caucasians and tanned Caucasians. Four is your skin tone for lighter ethnic tones such as Asian, Hispanic, and Middle Eastern dissent. Five and six are your light skin and dark skin African-Americans along with those with darker pigment such as those individuals from India.

The 755 Alex is best for skin types I-III. The 810 diode is best for skin types I-IV. The 1064 Nd:YAG is best for skin tones V-VI. The YAG is also the only wavelength safe for all skin tones, this is due to the poor absorption of the 1064 wavelength into all three targets of hemoglobin water and melanin. This allows the wavelength to pass through the melanin in the skin and safely eradicate the hair follicle. IPL is best for skin tones I-III, and although providing lesser efficacy then a true laser can still be a very effective means of hair removal.

Hair removal lasers very from technology to technology and manufacturer to manufacturer. Certain lasers are more effective than others on certain patients and some lasers hurt less or more than other lasers. There is no perfect laser on the market however there may be a perfect laser for you. A professional consultation is highly recommended to choose the right technology for your practice.
