Claim Text:
1. A method of localizing thermal damage to a targeted component of a skin tissue with a surfactant composition, comprising: topically applying a composition comprising a surfactant and nanoparticles to a skin surface of a skin tissue; wherein the skin tissue comprises a targeted component of the skin tissue and a non-targeted component of the skin tissue, wherein the nanoparticles have at least one peak absorption wavelength selected from the group consisting of: 755 nm, 800-810 nm, and 1064 nm, wherein the nanoparticles are unassembled, wherein the nanoparticles have a concentration of 10 wherein the nanoparticles comprise a conductive metal portion comprising at least one of gold, silver, and platinum, wherein the nanoparticles comprise a coating that coats the conductive metal portion; targeting a pilosebaceous unit by redistributing a portion of the composition of nanoparticles from the non-targeted component of the skin tissue to the targeted component of the skin tissue while a remaining portion of the composition is left on the non-targeted component of the skin tissue; removing the remaining portion of the composition from the non-targeted component of the non-targeted component of the skin tissue; and irradiating the composition of nanoparticles with an energy source to induce a surface plasmon in said nanoparticles, thereby localizing thermal damage to said targeted component of the skin tissue.
