The present invention relates to a sheet structure for application to a region of the human body, including the face, the structure comprising: a colored matrix; a first substrate situated on a first side of the matrix, a first surface of the sheet structure being defined by the first substrate; and a second substrate situated on a second side of the matrix, opposite the first, a second surface of the sheet structure being defined by the second substrate; the first and second substrates having different opacities, and at least one of the first and second substrates having an opacity that is low enough to enable the subjacent colored matrix to show through in such a manner that the first and second surfaces of the matrix appear to be of different colors.
