A device and method for selectively applying a composition a treatment surface (e.g., skin) to impart an aesthetically pleasing appearance to the surface. The device may include a detector for obtaining image data corresponding to an image of an area of skin. The device may also include an applicator for selectively applying a fixed amount of the composition to the skin to a location within the area of skin as determined by the device. The fixed amount is selected to reduce the artifact magnitude by a predetermined coverage level when applied to the skin. The device may include a processing arrangement for receiving image data from the detector, determining an artifact magnitude of the location based on the image data, comparing the artifact magnitude to a threshold, and directing the applicator to apply the composition to the skin when the artifact magnitude is above the threshold.
