Device for administering fluid compositions including tensioning polymers

1. A device for applying a fluid composition to the skin, said device comprising (i) a reservoir containing said composition, said composition comprising at least one tensioning polymer present in an amount of from about 0.5 to about 20% by weight and selected from at least one of a protein, a protein hydrolyzate, a proteoglycan/glycoaminoglycan, and a polysaccharide; and (ii) a skin-contactable surface having from about 5 to about 25 openings wherein said openings are of at least two different sizes the first size opening having an area that is at least twice the area of the second size opening wherein said device is adapted such that said fluid composition may be extruded from such reservoir to said skin-contacting surface through said openings and wherein said device is in the shape of elongate shell having an imaginary longitudinal axis that forms an acute angle of from about 35 degrees to about 60 degrees with said substantially planar skin-contactable surface.

2. A device of claim 1 wherein said skin contactable surface has a surface area less than about 100 square millimeters.

3. A device of claim 1 wherein said skin contactable surface has a surface area less than about 40 square millimeters.

4. A device of claim 1 wherein said skin contactable surface has a surface area less than about 15 square millimeters.

5. A device of claim 1 wherein said skin contactable surface is substantially planar.

6. A device of claim 1 wherein said skin contactable surface is devoid of openings having an area greater than about 4 square millimeters.

7. A device of claim 1 , wherein said skin-contacting surface has from 1 to 12 of said first openings and has from 2 to 12 of said second openings.

8. A device of claim 1 , wherein said at least one tensioning polymer is present in a concentration by weight of at least about 2%.

9. A device of claim 1 , wherein said at least one tensioning polymer has a contractile force greater than about 3 grams/milligram.

10. A device of claim 1 , wherein said composition has a viscosity from about 10,000 cps to 90,000 cps.

11. A device of claim 1 , wherein said device further comprising a plunger adapted for extruding said fluid composition from said reservoir to said skin-contacting surface through said openings, said device adapted for controlled displacement of said plunger in increments less than about 0.1 mm.

12. A device of claim 11 , wherein the said device is adapted for extruding said fluid composition from said reservoir to said skin-contacting surface through said openings in an amount from about 0.001 cc to about 0.01 cc.

13. A device of claim 1 , wherein the said device is adapted for extruding said fluid composition from said reservoir to said skin-contacting surface through said openings in an amount from about 0.001 cc to about 0.01 cc.

14. A method for applying a fluid composition to the skin using the device of claim 1 , said method comprising (i) extruding said fluid composition from said reservoir to said skin-contacting surface through said openings extruding said fluid composition through said openings onto said skin and (ii) applying said extruded fluid composition to said skin.

15. A method of claim 14 , wherein the said device is adapted for extruding said fluid composition from said reservoir to said skin-contacting surface through said openings in an amount from about 0.001 cc to about 0.01 cc.

16. A method of claim 14 , wherein said skin is adjacent the forehead, eyes, cheeks, nose, jowels, or chin.

17. A method of claim 14 , wherein the composition is a water-in-oil emulsion.
