Studies of Lumiville™.

Red light therapy has been researched and documented in peer-reviewed clinical studies for over two decades. The Lumiville™ GlowPro uses 630nm red light — the wavelength most extensively studied for skin collagen support, cellular renewal and visible improvement in fine lines and skin tone. Below is a summary of the clinical research behind the technology.

How Red Light Therapy Works

Red light at the 630nm wavelength penetrates through the epidermis and reaches the dermis which is approximately 4mm below the surface of the skin. This is the layer where collagen and elastin live, where fine lines form, and where creams and topical products cannot reach. Once absorbed by skin cells, red light stimulates mitochondrial activity — the energy production process inside your cells. This increase in cellular energy triggers the natural production of collagen and elastin, accelerates tissue repair and supports the skin's own renewal process from within. The result over consistent use is visibly firmer, smoother and more radiant skin.

Clinical Research

Wunsch A, Matuschka K. A Controlled Trial to Determine the Efficacy of Red and Near-Infrared Light Treatment in Patient Satisfaction, Reduction of Fine Lines, Wrinkles, Skin Roughness, and Intradermal Collagen Density Increase. Photomedicine and Laser Surgery. 2014.

This controlled clinical trial examined the effects of red and near-infrared light therapy on human skin. Participants who received red light treatment showed statistically significant improvements in skin complexion, skin texture and overall skin feeling compared to the placebo control group. Crucially, intradermal collagen density — measured objectively using ultrasound imaging — increased significantly in the treatment group. The study concluded that red light therapy is a safe and effective method for improving skin appearance and increasing collagen density without adverse effects.

This comprehensive review examined the existing body of clinical evidence for low-level light therapy applied to skin conditions. The researchers found consistent evidence across multiple studies that red and near-infrared wavelengths stimulate fibroblast activity — the cells responsible for producing collagen and elastin. The review documented measurable improvements in wound healing, skin rejuvenation, reduction of fine lines and improvement in overall skin tone and texture. The authors noted that red light therapy operates through photobiomodulation — a process where light energy directly influences cellular behaviour — and concluded that it represents a clinically validated approach to non-invasive skin improvement.

This study specifically examined 660nm LED light — the wavelength closest to the 630nm red light used in the Lumiville™ GlowPro — and its direct effect on collagen metabolism in skin tissue. The laboratory component demonstrated that pulsed LED light at this wavelength significantly increased procollagen synthesis while simultaneously reducing the enzymes responsible for collagen breakdown. The clinical trial component confirmed these findings in human participants, showing visible improvement in periorbital wrinkles and overall skin quality. The authors concluded that LED light therapy at this wavelength represents a clinically effective and non-invasive method for improving skin collagen density and reducing visible signs of ageing.

Hamblin MR. Mechanisms and applications of the anti-inflammatory effects of photobiomodulation. AIMS Biophysics. 2017.

This peer-reviewed paper examined the anti-inflammatory mechanisms of light therapy across multiple wavelengths including red light at 630nm. The research found that red light therapy modulates inflammatory pathways in skin tissue, reducing redness, supporting barrier function and calming sensitised skin. This mechanism supports the use of multiple light modes — including the green and yellow wavelengths in the Lumiville™ GlowPro — for concerns such as uneven tone, redness and pigmentation.

What This Means

The Lumiville™ GlowPro brings the same wavelength technology documented across these peer-reviewed studies directly into your home routine. 10 minutes of consistent daily use allows the light to work at the cellular level — where creams and serums cannot reach — supporting your skin's natural ability to renew, firm and glow from within.

Results vary between individuals. Consistent daily use is recommended for best results.
