Photosynthesis has used sunlight as its primary energy source for more than three billion years. In this process, solar energy is captured as electron flow. Using carbon dioxide (CO₂) as a substrate, plants split water to produce oxygen and sugars. Cellular respiration, by contrast, converts sugars and oxygen back into carbon dioxide and water. Life depends on this cycle of photosynthesis and respiration across plants, animals, and humans. Through evolution, chloroplasts and mitochondria both descend from ancient bacteria capable of harvesting photon energy and transferring it to their host cells.​ Dr. Otto Warburg pioneered research on photosynthesis and laid the foundation for our understanding of light–life interactions. Since then, numerous discoveries have explored how light and water influence biology. Dr. Gerald Pollack’s work on the so-called “fourth phase” of water is one notable line of research, proposing that structured water may help living systems interact with light. Recent studies further suggest that specific wavelengths can act on the epidermis to influence water structuring and oxygen dynamics.

Building on nature’s principles of photosynthesis, CHI Twinlight applies Airnergy technology in the form of light to tap into the body’s latent energy via a proprietary bio-electric excitation process. CHI Twinlight extends Airnergy’s approach by using a monochromatic light source directed at the epidermis to encourage the formation of fourth-phase water–like structuring and oxygen from water molecules. The result is not just superficial red-light therapy but a deeper stimulation of the body’s own energy field. In this way, light, water, and life converge — awakening the body’s natural capacity to repair, regenerate, and thrive.
