Abstract

A prosthetic eyelash unit includes a base with a plurality of follicle areas located within the base. The prosthetic eyelash unit includes a plurality of artificial hairs extending from the plurality of follicle areas located within the base and through a front surface of the base. The base is designed to attach at least in part to a lash line of a user to form a prosthetic lash line.

First claim

What is claimed is:

1. A prosthetic eyelash unit, comprising:
a base comprising a front surface, a rear surface opposite the front surface, and a plurality of follicle areas located within the base, wherein the base is a monolithic structure;
a plurality of artificial hairs extending from the plurality of follicle areas located within the base and through the front surface of the base, wherein at least a portion of the rear surface of the base is designed to bend between an upper lengthwise side of the base and a lower lengthwise side of the base to form a curvature, wherein the curvature attaches to and at least in part covers one or more natural hair follicles of a lash line of a user to form a prosthetic lash line; and
a hair attachment layer to which the plurality of artificial hairs are woven.

2. The prosthetic eyelash unit of claim 1 , wherein the base is further configured to bend to form another curvature that extends along a lengthwise side of the base, and wherein the base is formed at least in part of a flexible material.

3. The prosthetic eyelash unit of claim 2 , wherein the flexible material of the base is a first material, the prosthetic eyelash unit further comprising:
the hair attachment layer comprising a second material different than the first material.

4. The prosthetic eyelash unit of claim 3 , wherein the hair attachment layer is embedded within the flexible material of the base.

5. The prosthetic eyelash unit of claim 3 , wherein the hair attachment layer is attached at the rear surface of the base.

6. The prosthetic eyelash unit of claim 2 , wherein the flexible material of the base comprises silicone.

7. The prosthetic eyelash unit of claim 1 , wherein the plurality of follicle areas are positioned at different locations along the base, and wherein one to three artificial hairs of the plurality of artificial hairs extend from each of the plurality of follicle areas.

8. The prosthetic eyelash unit of claim 1 , further comprising:
a plurality of prosthetic eyelash segments each comprising the base and the plurality of artificial hairs, the prosthetic eyelash segments designed to align adjacent to one another at the lash line of the user.

9. The prosthetic eyelash unit of claim 1 , the base further comprising:
a lash line portion comprising the plurality of artificial hairs and designed to attach to the lash line of the user.

10. The prosthetic eyelash unit of claim 9 , the base further comprising:
an eyelid portion monolithically coupled with the lash line portion, the eyelid portion designed to attach to a front surface of an eyelid of the user.

11. The prosthetic eyelash unit of claim 1 , wherein the front surface of the base comprises an elongated shape defined by a colorant, the elongated shape configured to resemble eyeliner.

12. The prosthetic eyelash unit of claim 1 , wherein an artificial hair of the plurality of artificial hairs comprises:
a shaft; and
a root area connected to the shaft, the root area to secure the artificial hair to the base.

13. The prosthetic eyelash unit of claim 12 , wherein the root area of the artificial hair is located within the base or at the rear surface of the base.

14. The prosthetic eyelash unit of claim 1 , further comprising:
an adhesive layer coupled to the rear surface of the base.

15. The prosthetic eyelash unit of claim 14 , wherein the adhesive layer comprises a moisturizing component to moisturize skin at the lash line.

16. The prosthetic eyelash unit of claim 1 , wherein the lash line of the user is an upper lash line.

17. The prosthetic eyelash unit of claim 1 , wherein the lash line of the user is a lower lash line.

18. The prosthetic eyelash unit of claim 1 , wherein at least part of the front surface of the base comprises a skin-tone colorant.

19. The prosthetic eyelash unit of claim 1 , wherein a depth of the base ranges between 0.1 millimeters to 0.9 millimeters.

20. The prosthetic eyelash unit of claim 1 , wherein the plurality of artificial hairs are attached to the base by an attachment process that pulls each of the plurality of artificial hairs through the base.
