Approximately 700 subjects will be enrolled at approximately 12 clinical sites in the U.S.A.\n\nEffectiveness will be determined by the degree of frown line reduction, during maximum forced frown and at rest (neutral expression):\n\n* as assessed live by the study doctor,\n* as assessed live by the subject, and;\n* as assessed by an independent reviewer based on subject photographs\n\nFrown lines are graded on level of severity based on this scale:\n\nSeverity\n\n* Minimal (0)\n* Mild (1)\n* Moderate (2)\n* Severe (3)\n\nThere are two parts to this study. In the first part, all study participants will receive treatment with an intramuscular injection of 30 Units of Mentor Purified Toxin on two separate occasions (Cycles 1 and 2) no more than 6 months apart. In the second part of the study (Cycle 3), subjects will be randomly assigned to receive either intramuscular injections of 30 Units of Mentor Purified Toxin or placebo (preservative-free saline) and subjects will be followed for 1 month (3:1, PurTox : placebo).\n\nEach subject will receive five intramuscular injections for a total of 0.5 mL of study drug in the glabellar area, during each treatment visit. Participation takes place over a maximum of 14 months, including Part 1 (Cycle 1 and 2) and Part 2 (Cycle 3). The number of clinic visits will vary from person to person depending upon the subject's response to the study drug, but will range from approximately 9 to 19 clinic visits. There will also be up to 4 telephone follow-up contacts."}, 'eligibilityModule': {'sex': 'ALL', 'stdAges': ['ADULT', 'OLDER_ADULT'], 'minimumAge': '18 Years', 'healthyVolunteers': False, 'eligibilityCriteria': "Inclusion Criteria:\n\n1.

A history of psychiatric problems that, in the investigator's opinion, is severe enough potentially to interfere with subject outcomes;\n2. A history of autoimmune disease, that, in the opinion of the investigator, might interfere with subject outcomes (e.g., osteoarthritis is not considered an exclusion criteria; however, subjects with dermatomyositis are not permitted to participate in this study);\n3. A history or presence of clinically significant cardiovascular, respiratory, hepatic/biliary, renal, gastrointestinal, endocrinological, or neurological disorders constituting a possible risk factor that, in the investigator's opinion, is severe enough potentially to interfere with subject outcomes;\n4.

Current history of facial nerve paralysis;\n8.
