Abstract

An apparatus (27) for bio-stimulating phototherapy is herewith provided. The apparatus comprises a light source (29) for providing light with a phototherapeutic wavelength and a controller (37). The apparatus is configured for illuminating the skin (3)of a subject's body portion (1) with light emitted by the light source. The controller is configured to control operation of the apparatus, in particular the light source, such that the light is provided in a series of optical pulses with a controlled pulse repetition rate, with the pulses having a controlled pulse irradiance and pulse duration. The controller is configured to control the pulse irradiance the pulse duration and the pulse repetition rate as a function of at least one of the melanin index (M) and the lightness (L*) of the skin to provide an effective time averaged irradiance at or below a predetermined value. A method is also provided.
