The present invention relates to a composition comprising at least one sirtuin activator, preferably selected from quercitin, piceatannol, resveratrol and isonicotinamide, and having a carrier system for the at least one sirtuin activator, wherein the carrier system comprises lipid vesicles with one or more lipid membrane (s). In order to provide an improved effect of sirtuin activators in living skin cells, it is proposed according to the invention that the at least one sirtuin activator is contained in the lipid vesicles and the lipid vesicles have a positive surface charge, wherein the positive surface charge is caused by the Lipid vesicles in the / the lipid membrane / s in addition to the lipids of which the vesicles are composed of positively charged molecules as charge generators, these charge generators are selected from quaternary ammonium compounds. |
