Low intensity laser therapy (LLLT) uses monochromatic light from LEDs, typically in red and near-infrared wavelengths (600–1100 nm), for deep tissue penetration and effective cellular stimulation, especially in mitochondria for ATP synthesis.

This therapy enhances cellular metabolism by increasing RNA and protein synthesis, oxygen consumption, membrane potential, and ATP levels. Sessions are spaced every 72 hours to optimize efficiency, following the Arndt-Schulz law governing dose-response.

Thе tested mask emits a red light with a wavelength of 630 ± 10 nm and a power of 15 + Joules/cm², chosen for maximum efficiency based on scientific literature and the diodes' resistance limit.

The power density is at 21.7 mW/cm². Lumina Red's research opted for using red light to minimise risks and bias for at home use.

The decision was influenced by the separate sensitivity of the skin to red and infrared frequencies. Combining these wavelengths can lead to heat effects from near-infrared, which are mitigated when using red wavelengths alone.

The study included 20 healthy volunteers (15 women, 5 men) aged 45-70 (average age: 55.6 ± 7.39 years) with signs of skin aging.

• LifeViz Micro Photographs: Analyzed wrinkles (crow's feet) and skin roughness (upper cheek)
• Atlas of Cutaneous Aging: Dermatologists evaluated facial sagging on a 0-5 scale
• Cutometer: Measured skin firmness and elasticity using negative pressure
• Ultrasound: Assessed dermal density on the right cheek with a 20 MHz probe
• Proscope Macrophotographs: Visualized pore diameter on the cheek near the nose
• Chromameter CR400: Evaluated complexion homogeneity by measuring luminosity differences on the cheek
• Skin Diagnostic SD 207: Measured sebum levels on the cheek near the nose for subjects with mixed to oily skin (10 volunteers)
• Visiopor: Visualized porphyrin levels in pores on the left cheek near the nose using UV light for subjects with mixed to oily skin (10 volunteers)

Clinical studies shows excellent dermatological tolerance and anti-aging effectiveness of Lumina Red Light mask on days 30, 60 and 90 of use.

From the first month of use (D28), a significant improvement in the following parameters was observed:

• 15.6% decrease in the depth of crow's feet wrinkles
• 5.4% decrease in the clinical score of facial slackening
• 13.6% decrease in the R0, value indicating a firming effect
• 26.4% increase in dermal density
• 6.8% decrease in cheek roughness
• 28.5% decrease in pore diameter, indicating a smoothing effect
• 34.9% decrease in the quantity of sebum

After 2 months of use (D56), further improvement in the above parameters was noted, along with:

• 12.5% increase in skin elasticity
• 32.7% increase in skin tone homogeneity

After 3 months of use (D84), all parameters analysed showed further improvement compared to the values obtained at D56 and significant decrease in the depth of the crow's feet wrinkle was observed:

15.6% after 28 days of mask use, 34.7% after 56 days, and
38.3% after 84 days.

The satisfaction survey after 2 and 3 months showed promising results: 100% of volunteers reported significant improvement in overall skin condition, with 85% feeling positive after each session.

Results from both men and women, despite the small number of men (five), were consistent after 3 months:
- 16.7% reduction in facial oval sagging,
- 31.3% increase in skin firmness (measured by R0 value),
- 62.1% increase in dermal density,
- 28.1% decrease in pore size,
- 62.6% decrease in sebum levels.

Measurements taken 14 and 28 days post-treatment cessation confirmed long-lasting effects on wrinkles, sagging, firmness, density, skin texture, pore size, complexion, sebum, and porphyrin levels, maintaining results comparable to those after 3 months of mask use.
