Stronger & Fuller Hair
Red/NIR light stimulates follicles and improves blood flow to the scalp. A 24-week study showed a 39% increase in hair density using NIR light (Lasers in Medical Science, 2022).
Natural Pain Relief
Studies show RLT reduces joint pain and inflammation by up to 70% in arthritis sufferers using NIR light (Clinical Bioenergetics, 2023).
Faster Recovery
RLT improves circulation and speeds muscle and tissue healing. A clinical trial showed 42% faster muscle recovery in athletes using RLT (Journal of Strength & Conditioning Research, 2023).
Healthier Skin
RLT boosts collagen and reduces inflammation—perfect for acne, ageing, and skin issues. One study showed a 54% collagen increase after 12 weeks of red light use (Journal of Cosmetic Dermatology, 2025).
Deeper & Longer Sleep
Red light helps regulate melatonin and soothe the nervous system. Insomnia sufferers had a 67% improvement in sleep quality after nightly RLT sessions (Sleep Medicine Reviews, 2022).
Fertility & Hormonal Health
RLT improves blood flow and hormone regulation in men & women. In women with infertility, 22.3% achieved pregnancy with 830nm light, and 50% of those resulted in live births (Ohshiro et al., 2014).
Heightened Mood
RLT leads to the release of melanopsin which helps lift mood. Just 4 weeks of use led to a 60% drop in depression and 70% drop in anxiety (Brain Sciences, 2023).
Increased Metabolism
RLT activates mitochondria in fat cells, aiding fat breakdown. Participants lost 1.4 cm from waistlines after 6 weeks of use (Lasers in Surgery and Medicine, 2022).
