An applicator configured for administration of a skin augmentation composition to a skin and/or sub cutis of a subject, said applicator comprising: a substrate, wherein said substrate has a generally flattened structure having two opposing surfaces, wherein one surface is intended for being placed proximal to the skin of a subject and the other surface facing away from the skin of the subject; and an array of microneedles, wherein the array of microneedles is located on the surface proximal to the skin of the subject, the array comprising a multiplicity of microneedles, wherein each of said microneedles comprises: a skeleton made of a rigid material, said skeleton comprises: a sharp tip section located on one end of said skeleton, said sharp tip section being configured to penetrate a skin of a subject; a base on an opposing end of said skeleton; a middle section connecting between said sharp tip section and said base; and a skin augmentation composition comprising at least one biocompatible ceramic material, wherein: • said skin augmentation composition at least partly surrounds said middle section, such that a diameter of said sharp tip section is larger than a diameter of said augmentation composition, such that said sharp tip section shelters, from the direction of the skeleton's longitudinal axis, all of said skin augmentation composition, • said base is having a length equal or higher than the thickness of the epidermis at the treated area, • said sharp tip section and said base of said microneedle are devoid of said skin augmentation composition, and prevent delivery of the skin augmentation composition to the epidermis, or to the epidermis and upper dermis. a substrate, wherein said substrate has a generally flattened structure having two opposing surfaces, wherein one surface is intended for being placed proximal to the skin of a subject and the other surface facing away from the skin of the subject; and an array of microneedles, wherein the array of microneedles is located on the surface proximal to the skin of the subject, the array comprising a multiplicity of microneedles, wherein each of said microneedles comprises: a skeleton made of a rigid material, said skeleton comprises: a sharp tip section located on one end of said skeleton, said sharp tip section being configured to penetrate a skin of a subject; a base on an opposing end of said skeleton; a middle section connecting between said sharp tip section and said base; and a skin augmentation composition comprising at least one biocompatible ceramic material, wherein: • said skin augmentation composition at least partly surrounds said middle section, such that a diameter of said sharp tip section is larger than a diameter of said augmentation composition, such that said sharp tip section shelters, from the direction of the skeleton's longitudinal axis, all of said skin augmentation composition, • said base is having a length equal or higher than the thickness of the epidermis at the treated area, • said sharp tip section and said base of said microneedle are devoid of said skin augmentation composition, and prevent delivery of the skin augmentation composition to the epidermis, or to the epidermis and upper dermis. a sharp tip section located on one end of said skeleton, said sharp tip section being configured to penetrate a skin of a subject; a base on an opposing end of said skeleton; a middle section connecting between said sharp tip section and said base; and a skin augmentation composition comprising at least one biocompatible ceramic material, wherein: • said skin augmentation composition at least partly surrounds said middle section, such that a diameter of said sharp tip section is larger than a diameter of said augmentation composition, such that said sharp tip section shelters, from the direction of the skeleton's longitudinal axis, all of said skin augmentation composition, • said base is having a length equal or higher than the thickness of the epidermis at the treated area, • said sharp tip section and said base of said microneedle are devoid of said skin augmentation composition, and prevent delivery of the skin augmentation composition to the epidermis, or to the epidermis and upper dermis. • said skin augmentation composition at least partly surrounds said middle section, such that a diameter of said sharp tip section is larger than a diameter of said augmentation composition, such that said sharp tip section shelters, from the direction of the skeleton's longitudinal axis, all of said skin augmentation composition, • said base is having a length equal or higher than the thickness of the epidermis at the treated area, • said sharp tip section and said base of said microneedle are devoid of said skin augmentation composition, and prevent delivery of the skin augmentation composition to the epidermis, or to the epidermis and upper dermis.
