The present invention describes compositions and methods for treating, preventing and improving the appearance of skin, particularly, treating, preventing, ameliorating, reducing and/or eliminating fine lines and/or wrinkles of skin, wherein the compositions include limonoid constituents which inhibit acetylcholine release at neuromuscular junctions of skeletal muscle so as to relax the muscles involved with wrinkling, folding and creasing of skin, e.g., facial movement and expression. The limonoids preferably include the plant alkaloids toosendanin and azadirachtin. The compositions, which also are used to treat hyperhidrosis, are preferably applied to the skin, or are delivered by directed means to a site in need thereof.

1. A method for treating wrinkles and/or fine lines of the skin, comprising administering to a subject in need of treatment a composition comprising one or more limonoid constituents in an amount effective to ameliorate, reduce, and/or eliminate wrinkles and/or fine lines.2. The method according to claim 1, wherein the composition is a topical composition.3. The method according to claim 2, wherein said composition is applied for a period of time effective to ameliorate, reduce, and/or eliminate wrinkles and/or fine lines.4. The method according to claim 1, wherein the one or more limonoid constituents is selected from toosendanin, azadirachtin, or a combination thereof.5. The method according to claim 3, wherein the composition is applied once daily for at least one week.6. The method according to claim 1, wherein the one or more limonoid constituent is present in an amount of from about 0.0001 wt % to about 10 wt % of the total weight of the composition.7. The method according to claim 1, wherein the one or more limonoid constituent is present in an amount of from about 0.0005 wt % to about 5 wt % of the total weight of the composition.8. The method according to claim 1, wherein the one or more limonoid constituent is present in an amount of from about 0.001 wt % to about 1 wt % of the total weight of the composition.9. The method according to claim 1, wherein the composition comprises a cosmetically or dermatologically acceptable vehicle, carrier or diluent.10. The method according to claim 1, wherein the composition further comprises a sunscreen.11. The method according to claim 10, wherein the sunscreen is selected from the group consisting of avobenzone, cinnamic acid derivatives, octyl salicylate, oxybenzone, titanium oxide, zinc oxide and combinations thereof.12. The method according to claim 11, wherein the cinnamic acid derivative is octylmethoxycinnamate.13.
