Clinical Application of a New Near-Infrared Light-Emitting Diode with Broader Spectrum for Skin Rejuvenation and Hair Growth Enhancement

What the authors concluded

Skin rejuvenation showed significant improvements, with wrinkles decreasing by up to 27.22% and skin texture, elasticity, moisture, and density also improving. Hair growth evaluation indicated a 1.33% increase in hair count by 20 weeks, with high participant satisfaction and no adverse reactions reported." Comment: The energy densities (fluence) were calculated based on the reported total dose

Devices that emit this wavelength

Matched on wavelength within 15nm, since LED bins vary by roughly that much and a tighter match would be false precision. Where we have an irradiance figure, the session length is the time needed to reach this study's dose of 1.45 J/cm² at that intensity.

Matching a wavelength is not the same as reproducing a trial. Session times assume the device's published irradiance is accurate at the distance it was measured, which on brand-claim figures is often optimistic. Where a device publishes both a peak and an average we use the average, and where it publishes a falloff curve we use the lowest figure, so these times run long rather than short. Clinical protocols also control for spot size, contact and skin type in ways a home device cannot.
