Abstract: An apparatus for biophotonic tissue treatments comprising a wearable light emitter device, suitable to be configured to be applied to a body portion to be submitted to treatment. The light emitter device comprising a closed chamber, light guides being formed at the inside in order to transfer a preset-frequency light radiation at pre-fixed treatment points of the device. The light guides are connected to at least an optical fibre that direct thereof the light generated by at least a light radiation source arranged in a control unit for controlling the emission of light radiation. The control unit is operated by an operation unit for managing the treatment and for monitoring its implementation thereof according to set up parameters. The light guides being formed during the same production process and with the same material as the light emitter device.
