further comprising at least one crimping area or ferrule.

15. The brush head according to claim 1 , wherein said outer zone of bristles is outwardly tapered; and said tapered outer zone of bristles is configured for smoothing and/or buffing a liquid cosmetic applied to a surface from within said reservoir.

16. The brush head according to claim 1 , wherein said bristles in said outer zone and/or said inner zone have a wavy surface pattern, wherein the wavy surface pattern is defined by the tips of the bristles in said inner zone and/or said outer zone.

17. A method of using a brush head for applying a liquid cosmetic, comprising:

a) providing a surface on which to apply a liquid cosmetic;

b) providing a brush head comprising:

an outer zone of bristles, and

an inner zone of bristles, wherein a height of said inner zone of bristles is about 74% to about 90% of a height of said outer zone of bristles, wherein said inner zone of bristles has a pack density that is greater than a pack density of said outer zone of bristles, and wherein said inner zone of bristles and said outer zone of bristles define a reservoir;

c) applying the liquid cosmetic to said reservoir, wherein said reservoir retains said liquid cosmetic therein; and

d) transferring said liquid cosmetic from said brush head to said surface.

18. The method of claim 17 ,

wherein said surface is a human.

19. A method of using a brush for applying a liquid cosmetic, comprising:

a) providing a surface on which to apply a liquid cosmetic;

b) providing a brush head comprising:

an outer zone of bristles, and

an inner zone of bristles, wherein a height of said inner zone of bristles is about 74% to about 90% of a height of said outer zone of bristles, wherein said inner zone of bristles has a pack density that is greater than a pack density of said outer zone of bristles, and wherein said inner zone of bristles and said outer zone of bristles define a reservoir;

c) applying the liquid cosmetic to said reservoir, wherein said reservoir retains the liquid cosmetic therein; and

d) transferring said liquid cosmetic from said brush head to said surface.

20. The method of claim 19 , wherein said surface is a human.

21. A system for applying a liquid cosmetic, comprising:

a brush head comprising:

a) an outer zone of bristles, and

b) an inner zone of bristles, wherein said outer zone of bristles is outwardly tapered; wherein said inner zone of bristles and said tapered outer zone of bristles define a reservoir configured for holding a liquid cosmetic in place for application to a surface and said tapered outer zone of bristles is configured for smoothing and/or buffing a liquid cosmetic applied to a surface from within said reservoir.

22. The system according to claim 21 , wherein a height of said inner zone of bristles is about 74% to about 90% of a height of said outer zone of bristles.

23. The system according to claim 21 , wherein said outer zone and/or said inner zone of bristles comprise a wavy surface pattern, wherein the wavy surface pattern is defined by the tips of the bristles in said inner zone and/or said outer zone.
