IS LASER HAIR REMOVAL OCCAM'S RAZOR?
n the hands of a skilled practitioner laser hair removal is a rather
simple and long lasting procedure. If we interpret the words of William
Occam: "Why repeat a difficult task, when there is a more simple
solution?" Since the 14th century, this popular theorem has been known
as Occam's Razor. So why spend a lifetime shaving, when you could keep
it simple. When it comes to unwanted hair removal, Occam's Razor is
laser hair removal.
L.A.S.E.R., or Light Amplification by Stimulated Emission of Radiation, refers to the radiation of light beams, and is not to be confused with harmful ionizing or nuclear radiation. Lasers produce one wavelength of focused light. This differs from sunlight, which has many wavelengths (and is evident in the colors of a rainbow). Laser light is amplified, making it more powerful than light produced by typical light sources. For laser hair removal this focused and amplified light is pulsed on and off for an instant. This is not to be confused with IPL, Intense Pulsed Light that is not laser and can easily burn the skin. Lasers were first introduced to treat medical disease in the early 1970's. The first laser used for hair removal was the Ruby (694nm), introduced in 1995. The theory behind laser hair removal was developed at Wellman Laboratories of Photomedicine at Harvard. The Ruby Laser could only be used on fair-skinned individuals. Thus, lasers were developed offering 3 more wavelengths - 755nm, 810nm, and 1064nm, making it possible to customize laser hair removal for various skin tone and hair types. Lasers work by heating up a target. For laser hair removal, the target is hair just under the skin. At centers specializing in purely laser hair removal - like Ideal Image, it is important to have both the 755nm Alexandrite and the 1064nm YAG lasers by Candela Corporation. The combination of FDA-approved lasers allow treatment for all skin types, from light or fair skin, to dark black skin types. The most versatile laser and the primary laser used at Ideal Image is the Candela 755nm. It produces a 3-millisecond pulse targeting the color in the hair shaft, thus damaging the structure supporting the hair root. Lacking a supportive structure, the hair falls out. In all likelihood, it will not re-grow. Candela medical lasers are so selective; they can remove black ink from a white page without burning the white paper. In summary, they selectively destroy hair, leaving the skin undamaged. Candela lasers continually prove to offer the most comfortable service, while producing the most favorable results. At Ideal Image the means is the end. Thus, simplicity, safety, cost-effectiveness and long-term hair removal is the signature service provided. In conclusion, Occam's Razor is laser hair removal.
