Patent Claims: 1. A method of treating rosacea by orally-administering or topically-applying ivermectin in a dosage sufficient to fill and eliminate Demodex folliculorum mites from hair follicles in affected skin, resulting in cessation of the manifestations of allergic and vasomotor responses to the organism that cause the symptoms and signs of rosacea.

5. The method of claim 1, wherein said topically-applied ivermectin is formulated in a carrier lotion, cream, or gel.

6. The method of claim 5, wherein the concentration of ivermectin in said topically-applied lotion, cream, or gel is about one to five percent by weight.

7. The method of claim 5, wherein said topically-applied ivermectin is applied to affected skin areas but not to eyelids.

8. The method of claim 5, wherein said topically-applied ivermectin is applied to affected skin areas at least once and not more than twice daily for a period of about two to four weeks.
