CLINICAL EVIDENCE THROUGH INDEPENDENT TESTING
1. INDEPENDENT POWER DENSITY (MW/CM2) TESTING
An independent testing power density report, was conducted using a laser power meter. The comparison of products was carried out in a controlled test environment, showing the principles of fairness, justice and openness.
Power density value description: Our product has a patented design of silicone height, which will increase the distance from the LED to the product surface and expand the light-emitting area. According to the 120° light-emitting angle and the Pythagorean Theorem, the distance is 2mm, and the light-emitting area of a single LED Expanding from 19.62mm² to 28.95mm², the light has obvious attenuation during the propagation process. If the power density after a distance of 2mm can still meet the requirements, the test value is higher than other products, indicating that the effective area of our phototherapy products is larger than other manufacturers.
2. COVERAGE
Using an integrating sphere combined with a spectrum analyser to test luminous flux, space irradiance and colorimetry of phototherapy products.
The product works in a fixed and the same integrating sphere space irradiance total contrast value (visible light+ infrared light), this item is the most contrastive, because it gives a fixed space integrating sphere, internal 360° reflected light, including the irradiance of visible light and the irradiance of infrared light, no matter what the wavelength is or how many kinds of light there are, the tested irradiance is the comprehensive value of the product.
Spatial irradiance test value description: This value is carried out in a fixed same space, and the value does not represent the intensity of light on the LED surface, but the average irradiance value of the light after attenuation in this space, the values tested by various products can be compared, so as to judge the intensity of light and the level of energy.
3. PRECISION
Independent testing was conducted with a spectrometer to measure the LED wavelength.
Note: Light propagates along a straight line, and the energy of light begins to decrease as the propagation decreases 2. The spectrometer tests the light at a distance of 20cm - optical extraction is area and it is the same area's uniform source of light.
CLINICAL EVIDENCE THROUGH TRIALS
Combined 633-nm and 830-nm led treatment of photoaging skin. (Goldberg, 2006).
A clinical study to evaluate the clinical efficacy and ultrastructural changes in photodamaged skin after combined 633-nm and 830-nm light-emitting diode (LED) treatments. Thirty-six subjects received 9 LED treatments over the course of 5 weeks and were subsequently evaluated for final clinical improvement 12 weeks after treatment. Upon biopsy, it was established that there was a statistically significant improvement in wrinkles shown after profilometric analysis.
The majority of subjects reported improvements in softness, smoothness, and firmness at all time points. Electron microscopic analysis showed evidence of post-LED treatment of thicker collagen fibres.
Summary: 633-nm and 830-nm LED treatments play a role in the treatment of photodamaged skin. LED treatments can be used as either a primary or adjunctive treatment modality.
