  Hi, The problem with home laser hair removal systems is not that they are dangerous, but it is that they are generally ineffective. There are two considerations to an effective laser: 1) the type of laser used and 2) the energy settings. When it comes to home hair removal systems, they usually use an Intense Pulsed Light (an outdated precursor to real laser systems) or a diode or alexandrite laser. The IPL uses a flash lamp to produce a light beam which is significantly less focused than a laser beam, so it is less effective in permanently disabling follicles from producing hair. Diode and alex lasers, while highly effective for laser hair removal when used at the right settings, cannot safely treat dark or tanned skin at any setting. With regards to the energy settings, the fluence is an essential element in laser potency and effectiveness for permanent hair reduction. Fluence is quantified in joules per square centimeter(J/cm²). For permanent hair reduction, the energy level needs to be adequate to damage the hair follicle so that it is permanently disabled from growing hair, but not so high as to damage the skin and cause burns. Taking two home systems as examples, the Tria has an adjustable fluence level of between 7 and 20 joules and the Silk’n has a fluence level of 5 joules. True medical lasers used for laser hair removal have maximum fluence levels between 50 and 80 joules. A skilled laser practitioner will normally select an energy level of between 25 and 60 joules for an efficient treatment, i.e., the strongest setting your skin can handle without burning. The home systems simply lack the power to disable hair growth for a significant period. Considering the high cost of home-systems as compared to a professional treatment, your money is best spent on an effective system with a professional. http://www.assaralaserhairremoval.com/assarablog/
