Background/aims/methods: For the first time systematic measurements of the low‐level luminescence of the human skin (“bi‐ophotons”) have been performed by means of a photon detector device set up in darkness. Results: Several months of daily investigations have shown that body light emission follows definite and well‐known biological rhythms, such as 14 days, 1 month, 3 months, 9 months, and reflects the left‐right symmetry of the body. The results confirm that biophotons are related to physiological functions. Conclusions: This technique provides a new and powerful noninvasive diagnostic method. In particular, skin research and development may use it for testing the influence of different skin treatments.
