How does laser light pain relief work?
Better known as low-level laser therapy, Photobiomodulation, or soft-laser therapy is a mode of pain relief that utilizes light-emitting diodes to stimulate natural healing. While other forms of laser, such as those used in surgery, may cause damage to body tissues, laser therapy is different. Laser therapy uses low energy levels on the skin to stimulate the healing of body tissues. This type of laser is safe, non-invasive, and painless.
Laser therapy uses light-emitting diodes, which emit energy onto the skin. The light is absorbed by body cells to help in protein synthesis and cell division. This in turn helps improve blood circulation in the body to reduce inflammation and relieve pain.According to the Journal of Neuroinflammation red light therapy reduces the development of hypersensitivity and improves sensorimotor after spinal cord injury.

Laser light pain relief Clinical Study:
Abstract
The enhancement of skin's epidermal barrier recovery through light stimulation was assessed using porcine skin samples by monitoring the restoration of transepidermal potential (TEP), which measures the potential difference between the skin surface and dermis. Accelerated TEP recovery was noted with red light exposure at an irradiance of 40 mW/cm² for durations exceeding 10 minutes. Additionally, the light's effect on the surrounding area (~20 mm) was observed. In contrast, blue and purple light irradiation did not expedite barrier recovery. These findings are valuable for designing safe and effective phototherapy devices for skin. The study demonstrates that TEP can serve as a spatiotempOral indicator of epidermal barrier function.
Introduction
Light stimulation's thermal and chemical effects have been harnessed for both medical and cosmetic skin treatments. Various laser technologies are used for purposes like skin rejuvenation, scar removal, and wound healing. Additionally, LED use in skin care has shown promise, particularly in aiding the recovery of damaged epidermal barriers. Research on the photochemical responses of skin has indicated that photo-activated mitochondrial functions enhance epidermal cell morphology and proliferation. Notably, the presence of photoreceptor-like proteins in epidermal cells has been identified, suggesting that these cells can transduce light stimuli to promote barrier recovery and other skin functions.
Discussion
This study clearly demonstrated, using TEP values as novel indicators, that red light irradiation facilitates epidermal barrier recovery. Since the skin surface temperature remained unchanged during irradiation, the observed recovery is not attributed to thermal effects. The TEP change characteristics during light irradiation were consistent between conventional and probe-type systems. The latter directly measures local TEP, reducing the influence of surrounding tissues such as the dermis and hypodermis. This consistency indicates that the dermis has a negligible direct effect on the measured TEP in these experiments, despite reports that dermal fibroblasts respond to light stimuli. The absence of recovery promotion by blue/purple irradiation suggests that red light wavelengths (>600 nm) are particularly beneficial for skin barrier recovery. The physiological effects of red light irradiation appeared to extend about 20 mm from the irradiated point. Given the inverse square law of light irradiance weakening with distance, this "spread" effect is likely not directly induced by light but rather through other pathways, such as signaling between epidermal keratinocytes, which can induce calcium waves. Therapeutically, these results suggest that sufficient irradiance (~40 mW/cm²) can shorten light therapy durations for skin, and that device design can account for the spread of the stimulatory effect to surrounding areas. Since the therapeutic effects of red light irradiation have been validated with the clinically used TEWL method, and given the confirmed correlation between TEWL and TEP as barrier indicators, the accelerated barrier recovery measured by TEP in this study should be clinically relevant. TEP measurement provides a more convenient method for spatiotempOral testing of skin barrier conditions compared to conventional methods.
Conclusions
This study demonstrated that red light irradiation promotes epidermal barrier recovery, as evidenced by spatiotempOral TEP measurements. The recovery effect was linked to the restoration of the original TEP value, with optimal recovery conditions identified as an irradiance of ~40 mW/cm² for 10 minutes or more. The recovery effect also extended about 20 mm from the irradiated point. These findings are valuable for optimizing the design of light stimulation devices for effective, convenient, and safe skin treatments.
