Multi-functional personalized patch with therapeutic properties
Carefully coordinated patches having camouflaging and/or benefit properties can be formed for application to a desired region of human skin. The patches include a flexible film having a first, adhesive, outwardly facing major surface and a second outwardly facing surface which is textured to correspond to skin covered by the patch during use; wherein the flexible film further comprises at least one pigmented region and at least one region adapted to modify one or more optical properties selected from the group consisting of light transmission, light reflection, and light absorption. Methods of custom use of such patches may include 3D printing processes.
1. A method of camouflaging a blemish in a desired region of human skin comprising the steps of:
(a) providing image data relating to the desired region of human skin to a computer, wherein the computer converts the image data to geometric data representing a geometric model of the desired region of human skin;
(b) using the geometric data to control a 3D printer to print successive layers of flexible materials to form a patch for application to the desired region of human skin comprising a flexible film having a first, adhesive, outwardly facing major surface and a second outwardly facing surface which is textured to correspond to skin covered by the patch during use; wherein the flexible film further comprises at least one pigmented region and at least one region adapted to modify one or more optical properties selected from the group consisting of light transmission, light reflection, and light absorption; and
(c) applying the patch to the desired region of human skin.
2. The method of claim 1 further comprising using the geometric data to determine a subregion of the human skin in need of a benefit agent.
3. The method of claim 2 wherein the 3D printer prints a benefit agent in a subregion of the patch corresponding to the subregion of the human skin in need thereof.
4. The method of claim 3 wherein the benefit agent comprises an antibiotic.
