1. A packaging system for the in-situ preparation of cosmetic formulations, comprising a micromixer, wherein the micromixer comprises two or more thin sheet-like structures which are permanently connected to one another and which have repeatingly crossing channels in at least one of the surfaces facing one another having dimensions effective for intensive mixing within the micromixer, and two or more stock chambers, each having a thin tube, wherein each tube terminates in a channel of a micromixer, wherein mixing of the flowable components present from the different stock chambers can take place. 2. A packaging system according to claim 1, wherein the different stock chambers have a common pump system. 3. A packaging system according to claim 2, wherein the pump system, which is connected to the micromixer and has a dispensing aperture for the mixed product, is re-usable. 4. A packaging system according to claim 1, a wherein the stock chambers are under pressure. 5. A packaging system according to claim 1, wherein the stock chambers are individually connectable to a pump system, which is connected to the micromixer and has a dispensing aperture for a mixed product. 6. A packaging system according to claim 1, wherein the two or more stock chambers are connected externally to one another. 7. A packaging system according to claim 1, wherein the micromixer is made from metal, silicon or plastic structures. 8. A packaging system according to claim 1 for the in-situ preparation of cosmetic formulations in the form of lotions, emulsions, gels or creams. 9. A packaging system according to claim 1 for the in-situ preparation of liposome-containing formulations. 10. A packaging system according to claim 1 for the in-situ preparation of active ingredient-containing formulations. 11. A packaging system according to claim 1, further comprising a dispensing aperture for providing a mixed product immediately and directly to a user. 12. A package system according to claim 1, wherein a first stock chamber contains a first liquid comprising oil and a second stock. 13. A packaging system according to claim 12, wherein a resulting mixture is a microemulsion. 14. A packaging system for the in-situ preparation of cosmetic formulations comprising, a micromixer comprising two or more thin sheet-like structures which are permanently connected to one another and which have repeatingly crossing channels in at least one of the surfaces facing one another; and two or more stock chambers, each having a thin tube terminating in one of said channels; wherein intensive mixing of flowable components within said stock chambers occurs when said components flow from said stock chambers through said tubes into and through said channels. 15. A packaging system for the in-situ preparation of cosmetic formulations, comprising a micromixer, wherein the micromixer comprises two or more thin sheet-like structure which are permanently connected to one another and which have repeatingly crossing channels in at least one of the surfaces facing one another having dimensions effective for intensive mixing within the micromixer, and two or more stock chambers which are connected externally to one another. 16. A method of preparing cosmetic formulations in-situ, comprising mixing liquids intensively with a packaging system according to claim 15. 17. A method of preparing cosmetic formulations in situ, comprising mixing liquids intensively with a packaging system according to claim 14. 18. A method of preparing cosmetic formulations in-situ, comprising mixing liquids intensively with a packaging system according to claim 1.
