As laser technology continues to advance, physicians have choices regarding wavelengths, spot
sizes and pulse durations that can effectively target a specific chromophore while respecting the
surrounding epithelium in darker skin types. These advances allow for more efficient eradication of
chromophores, such as melanin, with less downtime.
The safety and efficacy of the long-pulsed The Elite MPX laser (Cynosure, Westford, MA) Alexandrite laser for treating solar lentigines has been a gold standard platform for laser hair has been reported.1 Thus, for patients with removal. With the dual-wavelength delivery of more diffuse dyschromia, or with greater areas the 1064nm Nd:YAG wavelength and the 755nm of solar lentigines, the long-pulsed Alexandrite Alexandrite wavelength, clinicians can titrate the laser may present a useful and effective percentage of each, and modify pulse durations alternative to the Q-Switched laser for to provide the most effective and safe destruction pigment reduction. of the hair follicle. However, the applications of Elite MPX are greater than hair removal alone. By utilizing the additional intense pulsed light (IPL) component, and isolating the Alexandrite wavelength in different spot sizes, the clinician is armed with a powerful solution to address both diffuse pigmentation and discreet melanin.
Melanin production occurs in the basal layer
of the skin in response to UV stimulation. The
absorption curve of melanin has a gradual slope;
therefore, there is no single "best" wavelength
for targeting this chromophore. However,
shorter wavelengths within the blue spectrum
or the green/yellow spectrum will be absorbed
better than longer wavelengths. Balancing
the wavelength, spot-size, and pulse duration
parameters will allow the clinician to target the
cosmetically concerning pigmentation.

Journal of Advancement in Medicine Volume 8, Number 2, Summer 1995 The Basis for Microcurrent Electrical Therapy in Conventional Medical Practice Joseph M. Mercola, DO and Daniel L Kirsch, PhD, DAAPM The use of electricity in medicine is not new. Clinicians used it over 150 years ago to treat non-union bone fractures. Electomedicine and nutrition, abandoned early in this century, have been recently revived. Most physicians are unaware of their therapeutic benefits. Electrotherapy, especiaily microcurrent electrical therapy (MET) is usefil for a variety of clinical conditions. Indeed, it may be the best treatment for many pain-related disorders, providing fast relief of symptoms and quickly promoting healing. It has significantly less side effects than drugs in chronic conditions. The more advanced MET devices can often demonstrate effectiveness with a simple two minute office procedure, allowing validity to be quickly assessed.
