A flexible device having a layered structure for delivering light or ultrasound to a skin surface. The device includes a flexible substrate that supports either a flexible light emitter layer or a flexible ultrasound emitter layer, as well as first and second flexible conductive layers. The device has a surface configured to face the skin surface, wherein (a) the light emitter layer emits pulsed light with an intensity that is substantially constant across the device's surface when driven by a power source connected to the conductive layers to thereby deliver a therapeutically effective dose of pulsed light to the skin surface or (b) the ultrasound emitter layer emits ultrasound with an intensity that is substantially constant across the device's surface when driven by a power source connected to the conductive layers to thereby deliver a therapeutically effective dose of ultrasound to the skin surface. |
