    3. A person who has skin abnormalities such as infections, skin diseases, scars, etc. at the site to be administered

    1. Within 4 weeks of screening: Drugs with muscle relaxation action, such as muscle relaxants, spectinomycin hydrochloride, aminoglycoside antibiotics, polypeptide antibiotics, tetracycline antibiotics, lincomycin antibiotics, anticholinergics, benzodiazepines and similar drugs, and benzamide drugs [However, for muscle relaxants, benzodiazepines and similar drugs, a person who has stably maintained administration of them from within 4 weeks from the time of screening (the same drug is maintained without changing the usage and dose), and is not expected to change in ingredients, usage, and dose of them during the clinical trial period can be enrolled]
    2. A person who has administered aspirin or NSAIDs within 7 days before administration of the investigational product (However, low-dose aspirin (100 mg/day or less) administered for antithrombotic purposes is permitted)

    1. Within 48 weeks of screening: Tissue augmentation
    2. Within 24 weeks of screening: A person who has undergone facial plastic surgery including glabellar lines such as brow lift, dermal resurfacing, or peeling, etc.

  6. A person who is planning to undergo facial cosmetic procedures such as dermal filler, photorejuvenation, chemical peeling, and dermabrasionduring the clinical trial period

  7. PT_BTA_P3_21 (Clinical Trial Plan Number) A person who received similar drugs for clinical trials such as botulinum toxin A and B after visiting the end of phase 3 clinical trials)

  8. A person who is expected to administer botulinum toxin formulations other than this investigational product during the clinical trial period

  9. A person with a history of hypersensitivity or allergy to the components of the investigational product (botulinum toxin formulations and serum albumin, etc.)

    2. Implantation of an intrauterine device or intrauterine system: A copper loop, hormone-containing intrauterine system
    3. Both men (condoms) and women (contraceptive diaphragms, vaginal sponges or cervical caps) use physical barrier methods together
    4. Surgical sterilization procedure/surgery: Bilateral tubal ligation, vasectomy, etc.
  13. Pregnant or lactating women

  14. A person with serious comorbidities (e.g., malignant tumors, immunodeficiency (decreased immune function), renal disease, liver disease, heart disease, respiratory disease, etc.) or acute diseases that are unsuitable for participation in the clinical trial as judged by the investigator
