Abstract

A method of removing a tattoo from skin of a human subject. The method has the step of applying to a region of the skin having the tattoo a reducing composition that includes a reducing agent and a penetration enhancer in admixture. The penetration enhancer is present in an amount effective to effect penetration of at least at least a portion of the reducing agent through the skin to the location of the tattoo. The reducing agent is present in an amount effective to at least partially decolorize or break up a pigment of the tattoo. The reducing agent can be selected from the group consisting of sodium oxymethylene sulfoxylate and sodium hydroxymethane sulfinic acid.

First claim

1 . A method of removing a tattoo from skin of a human subject, comprising: applying to a region of the skin having the tattoo a reducing composition, wherein the reducing composition includes a reducing agent and a first penetration enhancer in admixture in a first carrier different than the first penetration enhancer, wherein the first penetration enhancer is present in an amount effective to effect penetration of at least a portion of the reducing agent through the skin to the tattoo therein, wherein the reducing agent is present in an amount effective to at least partially decolorize or break up a pigment of the tattoo, and wherein the reducing agent is sodium oxymethylene sulfoxylate.

2 . (canceled)

3 . (canceled)

4 . The method of claim 1 , wherein the first penetration enhancer is selected from the group consisting of mineral oils, alcohols, polyols, fatty alcohols, and fatty acid esters.

5 . The method of claim 1 , further comprising applying, after a period of time, an oxidizing composition to the region of the skin having the tattoo.

6 . The method of claim 5 , wherein the oxidizing composition includes an oxidizing agent and a second penetration enhancer admixed in a second carrier.

7 . (canceled)

8 . The method of claim 8 , wherein the second penetration enhancer is present in an amount effective to penetrate the oxidizing agent through the skin to the location of the tattoo, and wherein the oxidizing agent neutralizes any remaining reducing agent.

9 . The method of claim 6 , wherein the oxidizing agent is an inorganic peroxide.

10 . The method of claim 9 , wherein the inorganic peroxide is hydrogen peroxide.

11 . (canceled)

12 . (canceled)

13 . The method of claim 1 , wherein the reducing composition further comprises a skin conditioning agent.

14 . (canceled)

15 . The method of claim 5 , wherein the second penetration enhancer is selected from the group consisting of mineral oils, alcohols, polyols, fatty alcohols, and fatty acid esters.

16 . The method of claim 1 , wherein the composition is applied to the skin once per day.

17 . The method of claim 1 , wherein the composition is applied to the skin multiple times per day.

18 . The method of claim 1 , wherein the composition is applied to the skin once per day for multiple days in sequence.

19 . The method of claim 5 , wherein the oxidizing composition includes water, an acrylates polymer, hydrogen peroxide, dimethicone copolyol meadowfoamate, simethicone, phosphoric acid, and a penetrating agent.

20 . A method of removing a tattoo from skin of a human subject, comprising: applying to a region of the skin having the tattoo a reducing composition, wherein the reducing composition includes a reducing agent and a penetration enhancer in admixture, wherein the penetration enhancer is present in an amount effective to effect penetration of at least a portion of the reducing agent through the skin to the tattoo therein, and wherein the reducing agent is present in an amount effective to at least partially decolorize or break up a pigment of the tattoo, and wherein the reducing agent is sodium oxymethylene sulfoxylate.

21 . A method of removing a tattoo from skin of a human subject, consisting of: applying to a region of the skin having the tattoo a reducing composition, wherein the reducing composition includes a reducing agent and a first penetration enhancer in admixture in a first carrier different than the first penetration enhancer, wherein the first penetration enhancer is present in an amount effective to effect penetration of at least a portion of the reducing agent through the skin to the tattoo therein, and wherein the reducing agent is present in an amount effective to at least partially decolorize or break up a pigment of the tattoo.

22 . The method of claim 21 , wherein the reducing agent is sodium oxymethylene sulfoxylate.
