Light Dose Database

76 patients received split face LED treatment with 830 nm, 633 nm, or a combination of 830 nm and 633 nm. The control group received a sham treatment. Patients received therapy twice a week for four weeks. Measuring skin elasticity and melanin revealed wrinkle reduction as high as 36% and up to 19% skin elacity increase. Researchers concluded that 830 and 633nm alone and in combination are effective wrinkle reducing wavelengths.

Researchers treated subjects with LED therapy the specific wavelength 660 nm (red for group 1) and a range of wavelengths from 411 to 777 nm (white for group 2). 52 women received 5.17 J daily for 12 weeks. Wrinkles significantly improved (reduced). Group 1 had slightly better results, but the differences were not significant.

30 women with no history of thyroid disease received 16 weeks of daily LED treatment in the neck area. Followup showed neck wrinkle reduction and no changes to the thyroid. This study includes only healthy participants. It does not test thyroid safety for subjects with a history of: benign thyroid disease, malignant thyroid disease, “keloid scarring, previous inflammatory or infectious skin diseases, uncontrolled medical illness, pregnancy,” or the use of growth factor-related cosmetics.

630 nm, 850 nm, 25 mW/cm2 (12.5 mW/cm^2 per color)

Increase lymphatic system activity correlated:

• reduced wrinkles
• reduced hyperpigmentation
• enhanced rejuvenation (glow)
• increased collagen
• decreased acne

Reduce wrinkles, increase collagen

Reverse collagen downregulation and MMP-1 upregulation, decreasing wrinkles, and increasing collagen.

Infrared Affect on Skin Review Rationale

Photobiomodulation researchers examined near infrared (NIR) studies that had resulted in damaged skin. The researchers determined that near infrared caused damage when applied in strong doses. Low dose NIR spread over time reduces wrinkles, produces collagen, and causes no harm.

Infrared Affect on Skin Review Hypothesis

Previous studies found near infrared photobiomodulation (PBM) damage because the doses were too high.

Infrared Affect on Skin Study Method

Examine PBM studies that showed near infrared light skin damage to correlate light doses with skin damage.

Infrared Affect on Skin Study Summary

In a review of Near Infrared photobiomodulation (PBM), use of near infrared light only caused damage when the dose was too high.

Near infrared light between 760 and 1,400 nm wavelengths rejeuvanates skin when applied in low (but not too low!) doses over time.

For more collagen and fewer wrinkles, use any of these wavelengths as frequently as once per day, at a dose of 20 to 50 mW/cm^2.

• 600 nm
• 805 nm
• 830 nm
• 900 nm

Infrared Review of Skin Effects Study Conclusion

• Ultraviolet (UV) and some infrared light frequencies are always harmful to the skin
• Near infrared with wavelengths between 760 nm and 1,400 nm are healthy when administered in a dose of 50 mW/cm^2 using any of these wavelengths: 660 nm, 805 nm, 830 nm, or 900 nm
• Wavelengths mentioned in the previous bullet point induce more collagen and elastin; result in better skin tone and fewer wrinkles.
• Use no more than 50 mW/cm^2, once a day or less.

“The body will absorb only so much energy before that energy damages the cytochrome cells.”

In every study reviewed, IR-A induced damage when the total energy absorbed was higher than one would receive from morning or evening sun.

Sunlight infrared is healthy when the shadows in the morning and evening, when the shadows are long. Noontime infrared creates oxidative stress. To get healthy artficial  infrared light, use no more than 50 mW/cm^2 of 660 nm, 805 nm, or 830 nm wavelength light.

EMF Channel Remarks on Infrared Review Publication

NIR frequencies can penetrate epidermis, dermis, and subcutaneous tissue.

To visualize what this means, the NIR light reaches all of this:

• epidermis: immune system and pigment cells
• dermis: hair follicles, nerve endings, sweat glands, oil
• subcutaneous tissue: connective tissue, fat, blood vessels

You can’t see infrared light. If you can feel it as heat, you’re getting too much.

Interestingly, if you use a high dose but simultaneously cool the skin, you can prevent thermal damage.

But this method isn’t tested for creating a healthy response. We just know that it prevents damage, not if it creates collagen and smoother skin.
