A skin radiation apparatus comprises: &mdasha photon radiation unit (10) for generating a line-shaped radiation pattern (12) extending in a first direction (x), the photon radiation unit comprising a photon radiation source (14), &mdasha movement facility (20, 22) for moving the line shaped radiation pattern in a second direction (y) transverse to the first direction (x), &mdasha detection unit (30) for detecting a skin condition profile, &mdasha control unit (40) for controlling an power density distribution for the line-shaped radiation pattern dependent on the skin condition profile detected by the detection unit (30).
