4. The personal car article of claim 3 , wherein the substrate skin treatment active and the coating skin treatment active are different.

5. The personal care article of claim 3 , wherein the substrate skin treatment active is an anionic surfactant.

6. The personal care article of claim 3 , wherein at least one of said substrate skin treatment active and said coating skin treatment active comprises a reducing agent.

7. The personal care article of claim 6 , wherein the reducing agent comprises a thiosulfate, a sulfite compounds, pepper oil, capsaicin, benzyl nicotinate, or a mixture thereof.

8. The personal care article of claim 6 , wherein an oxidizing agent is included in the substrate skin treatment active or the coating skin treatment active which does not include the reducing agent.

9. The personal care article of claim 8 , wherein said oxidizing agent comprises a peroxide.

10. The personal care article of claim 3 , wherein at least one of said substrate skin treatment active and said coating skin treatment active comprises an oxidizing agent.

11. The personal care article of claim 3 , wherein at least one of said substrate skin treatment active and said coating skin treatment active comprises a heat generating active comprising a water sensitive agent, a moisture sensitive agent, or a mixture thereof.

12. The personal care article of claim 11 , wherein said water sensitive agent comprises an anhydrous inorganic salt, a zeolite, a glycol, and a mixture thereof.

13. The personal care article of claim 3 , wherein at least one of said coating skin treatment active and said substrate skin treatment active comprises a water soluble lubricant having a molecular weight of from about 90,000 to about 10,000,000 grams/mol.

14. The personal care article of claim 1 , further comprising a second porous dissolvable solid substrate at least partially laminated to said first porous dissolvable solid substrate.

15. The personal care article of claim 14 , wherein the first and second porous dissolvable solid substrates are at least partially separated by said surface resident coating.

16. The personal care article of claim 1 , wherein said surface resident coating further comprises at least one surfactant.

17. A method of treating a surface comprising:

contacting a personal care article of claim 1 with water to allow said personal care article to at least partially dissolve;

applying said at least partially dissolved personal care article to a surface to form a prepared surface; and

optionally shaving said prepared surface with a razor.

18. A personal care article comprising:

a.) a first porous dissolvable solid substrate comprising:

iv. from about 10% to about 75%, by weight of the first porous dissolvable solid substrate, of at least one surfactant;

v. from about 10% to about 50%, by weight of the first porous dissolvable solid substrate, of a water-soluble polymer;

vi. from about 1% to about 30%, by weight of the first porous dissolvable solid substrate, of a plasticizer;

vii. from about 0.05% to about 2%, by weight of zinc pyrithione;

viii. optionally from about 0.05% to about 5% by weight of at least one of a metal oxide, metal hydroxide, metal carbonate, metal bicarbonate, and mixtures thereof; and

b.) optionally, a surface resident coating comprising from about 1% to about 70%, by weight of the personal care article, of at least one coating skin treatment active at least partially coating said first porous dissolvable solid substrate, wherein the ratio of the porous dissolvable solid substrate to the surface resident coating is from about 110:1 to about 0.1:1.

19. The personal care article of claim 18 , wherein the metal oxide is zinc oxide, the metal hydroxide is zinc hydroxide, the metal carbonate is zinc carbonate, and the metal bicarbonate is zinc bicarbonate.
