1. An anhydrous composition comprising a high molecular weight silicone component having a molecular weight between 100,000 and about 100,000,000 daltons and a low molecular weight silicone component, said low molecular weight silicone component consisting essentially of a low molecular weight linear silicone component, and wherein said composition further comprises a soluble or solubilized active component selected from the group consisting of retinoic acid, retinoic acid derivatives, retinal, retinol, retinyl esters and mixtures thereof; wherein the active component has increased stability when the composition is stored in a container for three months relative to the stability of the active component in an otherwise identical composition in which a cyclic low molecular weight silicone component is substituted for the low molecular weight linear silicone component and is stored in an identical container for the same period of time. 2. The composition of claim 1 wherein the active component has increased stability when the composition is exposed to higher than room temperature. 3. The composition of claim 1 wherein the high molecular weight silicone component is a dimethicone gum is capped with one or more groups selected from the class consisting of methyl groups, hydroxyl groups, phenyl groups, vinyls, amino groups and mixtures thereof. 4. The composition of claim 1 wherein the low molecular weight silicone is selected from the class consisting of low molecular weight dimethicones. 5. The composition of claim 1 wherein the low molecular weight silicone comprises hexadimethylsiloxane. 6. The composition of claim 1 wherein the active component is selected from the group consisting of retinoic acid, retinol, and mixtures thereof. 7. The composition of claim 1 wherein the active component comprises retinol. 8. The composition of claim 1 wherein the active component comprises about 0.001% to about 10% by weight of the composition. 9. The composition of claim 1, wherein the anhydrous composition is disposed within an opaque package. 10. The composition of claim 1, wherein the active component comprises about 0.01% to about 0.5% by weight of the anhydrous composition. 11. An anhydrous composition comprising a high molecular weight dimethicone gum component having a molecular weight between 100,000 and about 100,000,000 daltons, a low molecular weight silicone component consisting essentially of a low molecular weight linear silicone component, and a soluble active component selected from the group consisting of retinoic acid, retinoic acid derivatives, retinal, retinol, retinyl esters, and mixtures thereof, wherein the active component has increased stability when the composition is stored for at least 30 days and exposed to oxygen, light, and/or room temperature relative to the stability of the same active component in an otherwise identical composition in which a cyclic low molecular weight silicone component is substituted for the low molecular weight linear silicone component and is stored for the same period of time and under the same conditions. 12. The composition of claim 11 wherein the low molecular weight silicone is selected from the class consisting of low molecular weight dimethicones. 13. The composition of claim 11 which further comprises hexadimethylsiloxane. 14. The composition of claim 11 wherein the active component is selected from the group consisting of retinoic acid, retinol and mixtures thereof. 15. The composition of claim 11 wherein the active component is retinol. 16. The composition of claim 11 wherein the active component comprises about 0.0001% to about 10% by weight of the composition. 17. An anhydrous composition comprising a dimethicone gum component having a molecular weight between 100,000 and about 100,000,000 daltons, a low molecular silicone component consisting essentially of a low molecular weight linear dimethicone having a measurable vapor pressure at 25° C., and a soluble or solubilized active component selected from the group consisting of retinoic acid, retinoic acid derivatives, retinal, retinol, retinyl esters and mixtures thereof; the dimethicone gum and the low molecular weight dimethicone being present in the composition in an amount in a range of about 40-99.9% by weight, the active component having increased stability when the composition is placed into a clear container and exposed to sunlight for about three months relative to the stability of the active component in an otherwise identical composition in which the low molecular weight component is a cyclic siloxane stored under identical conditions for an identical period of time. 18. The composition of claim 17, wherein the active component is selected from the group consisting of retinoic acid, retinol and mixtures thereof, and is present in an amount of about 0.0001% to about 10% by weight of the composition. 19. The composition of claim 17, wherein the active component is retinol. 20. An anhydrous composition comprising a dimethicone gum component having a molecular weight between 100,000 and about 100,000,000 daltons; a low molecular weight silicone component consisting essentially of a linear dimethicone having a measurable vapor pressure at 25° C.; and a soluble or solubilized active component selected from the group consisting of retinoic acid, retinoic acid derivatives, retinal, retinol, retinyl esters and mixtures thereof. 21. The composition of claim 20 wherein said low molecular weight linear dimethicone is selected from the group consisting of a dimethicone and hexamethyldisiloxane.
