Claim Text:
1. A method of localizing thermal damage to a pilosebaceous unit, comprising: topically applying a composition comprising a surfactant and nanoparticles to a skin surface; 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 are provided in 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 skin surface to the pilosebaceous unit while a remaining portion of the composition is left on the skin surface; removing the remaining portion of the composition from the skin surface; and irradiating the composition of nanoparticles with an energy source to induce a surface plasmon in said nanoparticles, thereby localizing thermal damage to said pilosebaceous unit.
