Most effective laser hair removal device

It can be quite confusing with the dizzying array of machines available for laser hair removal.  Focus on the following factors to help simplify the process:

  1. Wavelength  -  Here the choices are limited to diode, Nd:YAG, alexandrite and IPL as the main laser hair removing modalities.  Diode laser hair removal devices are currently the gold standard, while Alexandrite lasers held that crown in the 1990's.  Nd:YAG lasers are primarily used on darker skin types.  IPL devices may have some long term efficacy but newer versions have improved.
  2. Cooling  -  Cooling is an important concept that most of the newer lasers embrace.  It allows for procedures to be relatively pain free.  In addition, cooling makes complications less likely.

Most Effective Laser Hair Removal Device

There is no single laser that is the best for all skin types. Dark skin requires a longer pulse and lighter skinned individuals see a better result with a shorter pulse. The long pulsed nd yag laser has been evaluated in peer-reviewed medical journals  as most effective for dark skin and the alexandrite has been evaluated as most effective for medium to light skin. It is important that you find a laser center owned and operated by a physician.
Never pay for packages as each person responds differently and a laser center that is confident about the performance of their lasers will provide pay as you go treatments, and a no charge, no pressure consultation.

Best Laser Hair Removal Treatment

Thank you for your question. A wide variety of medical lasers and light systems are used to remove unwanted hair, however most lasers are not effective for all skin types and hair colors. The Elos laser hair removal system is designed for permanent hair reduction by combining both optical and radiofrequency energy to deliver satisfying, longer lasting results with less discomfort than previous laser systems. All skin and all hair colors including gray and blonde hair are effectively treated. Faces, backs, arms, legs, faces, and bikini lines can be treated including those individuals with darkly pigmented skin. Treatments are administered every 4 weeks and generally 3 to 5 treatments are sufficient. Best of luck!

IPL, alexandrite, diode, and Yag lasers work well for hair removal.

Dear Martha,

The critical question is: Are you a good candidate for laser hair removal?

If you have light skin and dark hair, you should be satisfied with most FDA approved light devices.

Dark, coarse, fast growing hair like lip, chin, underarm, and bikini respond the best.

It takes between 6 and 10 treatments to get optimal, long-term results.

I hope this helps, and best regards.
