3. The composition according to claim 1 , wherein said peptide consists of the sequence Ala-Val -Leu-Ala-Gly-Asp (SEQ ID NO: 2).

4. The composition according to claim 1 , wherein said peptide possesses at least one functional group protected by a protector group, said protector group being either at least one of (i) an acylation or an acetylation of the amino-terminal end and (ii) an amidation or an esterification of the carboxyterminal end.

5. The composition according to claim 1 , wherein said active principle is present in the composition in a concentration between 0.0005 and 500 ppm approximately compared to the total weight of the composition.

6. The composition according to claim 5 , wherein said active principle is present in the composition in a concentration between 0.01 and 5 ppm compared to the total weight of the composition.

7. The composition according to claim 1 , wherein said active principle made soluble in one or more solvents cosmetically or pharmaceutically acceptable selected from the group consisting of water, glycerol, ethanol, propylene glycol, butylene glycol, dipropylene glycol, ethoxyl or propoxyl diglycols, cyclic polyols, petroleum jelly, a vegetable oil and mixtures thereof.

8. The composition according to claim 1 , wherein the composition is in a topical application form.

9. The composition according to claim 1 , further comprising at least one other active agent promoting the action of said active principle.

10. The composition according to claim 9 , wherein said other active agent is selected from the group consisting of active agents having an antioxidant action, active agents stimulating the synthesis of macromolecules, and active agents stimulating energy metabolism.

11. A method of preparing a cosmetic composition or a pharmaceutical composition according to claim 1 , comprising adding an effective amount of active principle to a physiologically acceptable medium.

12. A method of increasing the synthesis of intracellular ATP in the cells of the skin, comprising administering to a subject in need thereof a cosmetic composition according to claim 1 having an effective amount of active principle.

13. A method of increasing the activity or the synthesis of the enzyme transprenyl transferase and/or of the coenzyme Q10 in the cells of the skin, comprising administering to a subject in need thereof a cosmetic composition according to claim 1 having an effective amount of active principle.

14. A method of protecting the skin and the skin appendages against all types of external aggressions, comprising administering to a subject in need thereof a cosmetic composition according to claim 1 having an effective amount of active principle.

15. A method of preventing or treating damage caused to the skin and the skin appendages by UV rays, comprising administering to a subject in need thereof a cosmetic composition according to claim 1 having an effective amount of active principle.

16. A method of protecting the skin and the skin appendages from oxidative damage, comprising administering to a subject in need thereof a cosmetic composition according to claim 1 having an effective amount of active principle.

17. A method of preventing or treating the skin signs of aging and/or photoaging, comprising administering to a subject in need thereof a cosmetic composition according to claim 1 having an effective amount of active principle.

18. A method for preparing a pharmaceutical composition according to claim 1 for preventing or combating pathologies linked to the oxidation processes, comprising adding an effective amount of active principle to a physiologically acceptable medium.

19. A method of treating the skin and the skin appendages from external aggressions and to combat skin aging, comprising topically applying to the skin or the skin appendages of a subject in need thereof a cosmetic composition according to claim 1 .

20. The composition according to claim 1 , wherein said peptide consists of the sequence Ala-Val -Leu-Ala-Gly (SEQ ID NO: 3).

21. The composition according to claim 1 , wherein said peptide consists of the sequence Ala-Val -Leu-Ala-Gly-NH 2 (SEQ ID NO: 4).
