FREQUENTLY ASKED QUESTIONS NUMBER OF WAVELENGTHS ?
There is no magic wavelength, The target cell, Cytochrome C, is generously absorbing and responding to everything from 600nm out to 1064 and beyond. The trick is getting the light to the tissue with the help of Power. And blending 810 and 980nm based on skin color and other parameters, is the most well understood, and clinically proven approach.
WHAT ABOUT SUPERPULSING ? The “on” time, the pulse duration, is equal to microseconds (s 10-⁶) and nanoseconds (s 10-⁹). The dose of energy (amount of light) delivered to tissues is miniscule and does not allow to trigger the photobiomodulation in an optimal way. The literature does not support the claims made for this feature as it has been demonstrated that the optimal laser emission to trigger photobiomodulation must be continuous or pulsed with a pulse duration of at least few milliseconds (10⁻³ seconds), as stated by Hashmi, in 2010 in the article “Effect of Pulsing in Low-Level Light Therapy”.
Continuous Mode Example : Average Power = Peak Power = 25W Total Dose = Average Power x time = 25W x 10seconds = 250 Joules

Pulsed Mode Example : Peak Power = 300W Average Power = Peak power x Pulse time « on » duration x f = 1,35W Total Dose = Average Power x time = 1,35W x 10seconds = 13,5 Joules

ANY SIDE EFFECTS OF LIGHTFORCE THERAPY? Based on peer-reviewed literature, there are no known significant side effects from LightForce therapy for most conditions. Increased blood flow is a positive benefit associated with LightForce therapy that can cause the skin to get flush and the feeling of warmth. These changes are short-lived, typically lasting for up to a few hours. Understanding proper dosing parameters and the use of our Smart Handpiece minimize this phenomena.
WHY REPLACE MY “LLLT DEVICE” ? “Cold Laser”, “Low-Level Laser Therapy (LLLT)” and “Low- intensity Laser Therapy (LILT)” are all terms previously used in the laser therapy field. The main difference is the power available in the device. Class IIIb lasers are only delivering power < 0,5 watt when Class IV lasers are not limited except by technology and cooling function. Increased power enables the clinician to treat a larger area in a shorter time, thus allowing a more efficient delivery of a therapeutic dose to target tissues.

CAN LIGHTFORCE THERAPY BE USED WITH OTHER MODALITIES/TREATMENTS? Yes, it generally works well with other modalities that are designed to promote tissue repair. Best known example is shockwave devices. The mechanisms that are associated with this modality work well with LightForce therapy. Clinical proven benefits are being studied. Generally using modalities that are designed to provide cryotherapy, which generally reduce blood flow and promote vasoconstriction, is not recommended as adjunctive therapy with Lightforce.
