Evidence of light

LED light therapy technology is now supported by extensive scientific research. The wavelengths used in our Radiance FacePro LED Mask have been studied for their beneficial effects on the skin: improved radiance, reduced imperfections, support for skin regeneration, and soothing of signs of aging.

On this page, we share with you excerpts from scientific studies published in medical and specialized journals, along with their sources, so that you can explore the advances of this technology for yourself.

A transparent and enlightening way to understand why light, when used properly, becomes a true beauty ally.

“ Male facial rejuvenation using a combination 633, 830, and 1072 nm LED face mask ” By Mineroff

This study evaluated the efficacy and safety of an LED mask combining red and near-infrared light (633, 830, and 1072 nm), specifically designed for men's skin. After six weeks of home use, participants reported significant improvements in fine lines, texture, tone, and overall skin appearance, with high satisfaction and an intention to recommend the product. Digital photographic analysis also showed improvements in wrinkles, UV and brown spots, pores, and porphyrins. The mask is distinguished by its safety, efficacy, ease of home use, lack of discomfort or recovery time, and visible results in a short period.

“ Safety and efficacy of a novel home-use device for light-potentiated (LED) skin treatment ” By Guermonprez

This study evaluated a home device combining topical serum, LED light, and massage to combat skin aging. The principle is based on the synergy between the serum's active ingredients and visible/infrared light, in order to protect and rebuild the extracellular matrix. After 28 days of daily use, clinical results showed denser, brighter skin with fewer wrinkles, and no adverse effects.

“ Efficacy of Home-Use Light-Emitting Diode Device at 637 and 854-nm for Facial Rejuvenation: A Split-Face Pilot Study ” By Ng

This clinical study evaluated a home LED device (637 and 854 nm) for facial rejuvenation. Used twice a week for 8 weeks on 24 participants, it significantly improved skin elasticity, texture, and hydration, as well as wrinkles, without any adverse effects. Users reported a clear, progressive, and visible improvement. Conclusion: This device is safe, effective, and convenient as a complementary at-home anti-aging treatment.

“ Regulation of skin collagen metabolism in vitro using a pulsed 660 nm LED light source: clinical correlation with a single-blinded study ” By Barolet

This study evaluated the effect of 660 nm LED therapy on skin aging. Using a reconstructed skin model and then in elderly/photoaged subjects, LED therapy increased type I collagen production (+31%) and reduced the expression of MMP-1 (-18%), enzymes involved in dermal degradation. After 12 sessions, over 90% of participants showed a reduction in wrinkle depth and skin roughness, and 87% showed an improvement in wrinkle severity score. No adverse effects were observed. Conclusion: 660 nm LED therapy is a safe and effective method for stimulating collagen and improving skin appearance.

" A controlled trial to determine the efficacy of red and near-infrared light treatment in reduction of fine lines, wrinkles, skin roughness, and intradermal collagen density increase " By Wunsch & Matuschka

This controlled study of 136 volunteers evaluated two new polychromatic light sources (611–650 nm and 570–850 nm) for large-area, whole-body photobiomodulation. After 30 sessions, treated participants showed significant improvements in skin tone, skin feel, roughness, and collagen density, confirmed by clinical, photographic, and ultrasonographic analyses. No adverse effects were observed. Conclusion: These new light sources are
safe and effective for skin rejuvenation.

" A Comparison of red light and blue light therapies for mild-to-moderate acne vulgaris: A randomized controlled clinical study " By Li

This study of 28 patients with mild to moderate acne compared red light (RL) and blue light (BL). After treatment, both methods showed similar efficacy, with a more pronounced improvement in inflammatory lesions. However, RL demonstrated a slight advantage in terms of overall results.

“ A Comparative Study Between Once-Weekly and Alternating Twice-Weekly Regimen Using Blue (470 nm) and Red (640 nm) Light Combination LED Phototherapy for Moderate-to-Severe Acne Vulgaris ” By Nitayavardhana

This study of 30 patients with moderate to severe acne compared two LED phototherapy protocols: blue (470 nm) and red (640 nm) light. Two alternating weekly sessions were used, compared to one combined weekly session. Both protocols yielded equivalent results, with a marked improvement in inflammatory lesions visible as early as the first week after the end of treatment and maintained for up to eight weeks. No side effects were observed. Conclusion: LED phototherapy is safe and effective, and one weekly session may be sufficient for greater convenience.

“ Synergistic effects of using novel home-use 660- and 850-nm light-emitting diode mask in combination with hyaluronic acid ampoule on photoaged Asian skin: A prospective, controlled study ” By Dae Sung Kim

This study of 48 participants evaluated the synergistic effect of a home LED mask (660 & 850 nm) combined with a hyaluronic acid (HA) serum versus HA alone. After 4 weeks, both groups showed improvements in wrinkles, firmness, pores, and scaling, but the LED + HA combination produced faster and more pronounced results, with a significant increase in skin density. Conclusion: The combined use of an LED mask and HA is safe, effective, and optimizes the rejuvenation of photo-aged skin.
