| 摘要 |
The invention relates to a photoactivatable compound comprising a support molecule which is selected from among non-polymeric carbon and/or sulphur and/or nitrogen and/or phosphorous compounds, polymers and oligomers. At least two entities are covalently linked to the support molecule, said entities containing chemical groups which, after irradiation of between 200 and 450 nm, are transformed into reactive species that can react with chemical groups belonging to other molecules. The invention also relates to a cosmetic composition comprising at least one photoactivatable compound in accordance with the invention and to a cosmetic treatment method using said composition.
