Abstract

Background and Objectives
Low level light therapy (LLLT) is the therapeutic indication of light energy to achieve a clinical effect in an athermal and atraumatic way, and includes applications in wound healing and pain attenuation. Light emitting diodes (LEDs) have become the light source of choice with quasimonochromaticity giving laser-like target specificity, so LED-LLLT is amassing a growing body of solid evidence in the international literature.
Photobiological basics of LLLT
LLLT involves a direct energy transfer between incident photons and their target cells, boosting thecellular energy pool without causing heat or damage. If such photoactivated cells are compromised, they will be repaired. If they are functional cells, they will perform more efficiently If there are not enough cells, proliferation will occur. In LLLT, wavelength is of prime importance to ensure absorption in the targets, and also determines the intrinsic depth of penetration of the light energy into the target tissue: the light energy must also have sufficient intensity.
The ideal LED-LLLT
system The ideal LED-LLLT system should offer three wavelengths.. 415 nm in the visible blue is useful to control inflammatory acne. 633 nm visible red is particularly useful in photodynamic therapy (PDT) and some aspects of hair regrowth. 830 nm in the near infrared has a wide range of proven targets including, but not limited to, the following: all aspects of wound healing, acute or chronic, traumatic or iatrogenic; attenuation of pain of all entities, acute or chronic; bone repair; nerve repair; sports medicine; and hair regrowth. The HEALITE system (Lutronic Corporation, Goyang , South Korea) meets these criteria and has amassed a good number of panspeciality articles in the peer-reviewed literature. HEALITE embodies the true science of LEDLLLT.
