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 laser I recommend and use is the Elos laser hair removal system, which 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.
