The sheet structure e.g. masks or patches applied to a region of the human body e.g. face, comprises a colorful matrix, a first substrate (12) located a first side of the matrix, a first face (6) defined by the first substrate, a second substrate (13) located a second side of the matrix as opposed to the first, a second front (7) defined by the second substrate, and active cosmetics. The first and second substrates with different opacities and with low opacity to allow transpire matrix underlying colored so that the first and second sides of the matrix appear different colors. The sheet structure e.g. masks or patches applied to a region of the human body e.g. face, comprises a colorful matrix, a first substrate (12) located a first side of the matrix, a first face (6) defined by the first substrate, a second substrate (13) located a second side of the matrix as opposed to the first, a second front (7) defined by the second substrate. The first and second substrates with different opacities and with low opacity to allow transpire matrix underlying colored so that the first and second sides of the matrix appear different colors. The substrates are white color non-woven substrates. The color of the matrix is not uniform. The matrix is colored by the dispersion of colored particles. The colored particles have non-opaque external surface coating of transparent or translucent polymer. The colored particles comprise an inorganic core covered with a colored pigment skin. The colored particles are dispersed in the matrix with colored glass beads coated with a transparent polymer. The substrate have non-woven layers. The density of non-woven material is 5-30 g/m2>. The structure forms a mask or a patch to be applied to the skin and is packaged in a protective cover (2, 3).La présente invention concerne une structure en feuille (1) à appliquer sur une région du corps humain, y compris du visage, comportant:- une matrice colorée (10),- un premier substrat (12) situé dun premie
