The present invention more specifically relates to a cosmetic treatment method, in particular for improving the appearance of the skin and/or hair, including simultaneously and/or consecutively administering: at least one peptide agent increasing the expression of at least one substrate of cytochrome C oxidase, and optionally at least one substrate of cytochrome C oxidase; and at least one visible radiation having a predominant wavelength activating the cytochrome C oxidase. In particular, said visible radiation has at least one predominant wavelength activating the cytochrome C oxidase of 550 to 1000 nm, in particular 550 to 800 nm, preferably 620 to 700 nm, and most preferably 640 to 680 nm, and is preferably used at a dose of 0.01 to 200 J/cm 2 , preferably 0.1 to 30 J/cm 2 , more preferably 1 to 30 J/cm 2 , or even 5 to 30 J/cm 2 . The invention also relates to a composition and to a kit. |
