Claim Text:
1. A method of treating acne, comprising: topically applying a composition of nanoparticles to a skin surface, wherein the nanoparticles comprise a conductive metal portion, wherein the conductive metal portion comprises at least one of gold, silver, and platinum, wherein the nanoparticles comprise a coating that coats the conductive metal portion, wherein said coating is selected from the group consisting of a hydrophilic coating and a hydrophobic coating; wherein the nanoparticles are unassembled, wherein the nanoparticles have a concentration selected from the group consisting of: 10 distributing a portion of the composition from the skin surface to a sebaceous gland 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 with an energy wavelength selected from the group consisting of: 755 nm, 800-810 nm, and 1064 nm, thereby inducing a surface plasmon in said nanoparticles, thereby localizing thermal damage to said sebaceous gland to treat acne.
