A device and a method are for application of a composition to a treatment surface (e.g., skin). The device may include an optical emitter projecting fiducials to skin； a detector obtaining image data corresponding to an image of an area of skin marked with the fiducials； an applicator applying the composition to a location within the skin area； and a processing arrangement. The processing arrangement is receiving the image data, analyzing the image data to determine a morphology of the skin area based on the fiducials captured within the image, identifying, based on the morphology, a region within the image corresponding to the location aimed by the applicator arrangement, analyzing the image data to determine whether the identified region corresponds to a skin artifact, and directing the applicator arrangement to selectively apply the composition to the location when the skin artifact is detected from the identified region.
