         6 . The process as claimed in  claim 1 , wherein the composition also contains at least one additional active agent which stimulates the synthesis of extracellular macromolecules such as collagen IV and/or hyaluronan and/or fibronectin. 
     
     
         7 . The process as claimed in  claim 6 , wherein the additional active agent is an acyl oligopeptide. 
     
     
         8 . The process as claimed in  claim 1 , wherein the composition also contains at least one active agent chosen from: agents for stimulating elastin synthesis and anti-elastase agents, and mixtures thereof. 
     
     
         9 . The process as claimed in  claim 8 , wherein the anti-elastase agent is an extract of  Chlorella vulgaris.

         12 . (canceled) 
     
     
         13 . An extract of elemi or of  Canarium indicum  L. or of  Canarium luzonicum  or of  Canarium commune , which can be obtained according to the process described in  claim 5 . 
     
     
         14 . A cosmetic composition, which comprises, in a cosmetically acceptable medium, at least one extract as claimed in  claim 13 .

         16 . The process as claimed in  claim 2 , wherein the active agent is an extract of elemi or of  Canarium indicum  L. or of  Canarium luzonicum  or of  Canarium commune.    
     
     
         17 . The process as claimed in  claim 3 , wherein the active agent is an extract of elemi or of  Canarium indicum  L. or of  Canarium luzonicum  or of  Canarium commune.    
     
     
         18 . The process as claimed in  claim 2 , wherein the composition also contains at least one additional active agent which stimulates the synthesis of extracellular macromolecules such as collagen IV and/or hyaluronan and/or fibronectin. 
     
     
         19 . The process as claimed in  claim 2 , wherein the composition also contains at least one active agent chosen from: agents for stimulating elastin synthesis and anti-elastase agents, and mixtures thereof.
