An improvement in a light therapy device including multiple light-emitting diodes (LEDs) positioned in a handheld portable device is disclosed. Where the housing and the LEDs are configured to have direct contact with the skin or tissue of the user without any intermediary materials, and light the surface and underlying layers of tissue for photodynamic stimulation of the cells. Two iterations of the device utilize light known to have a bactericidal effect in the case or acne or Rosacea. The devices are fabricated from an injection molded plastic housing. The housing contains an arrangement of 36-72 LEDs on a circuit board in an arrangement to provide even lighting over the skin or tissue surface.
