- The evaluator at each institution assesses the severity level of glabellar wrinkles at the site in the field when the test subject frowns as much as possible according to the 4-point photographic evaluation table and classifies the subjects with a rating of ≥ 2 (medium or severe).
- Persons who can follow the test well, fully understand the clinical trial, rationally foresee the cost-effectiveness of injection, and adhere to the study procedure until the end of the clinical trial are selected.
- The test subjects fully understand the test requirements and voluntarily sign the consent form.
- Subjects who have a history of oversensitivity to the Botulinum Toxin A type, Botulinum Toxin B type, or other control groups of the tested drug substance.
- Subjects with clear scars, infections, a carcinogenic or cancerous metastatic lesion on the upper part of the face and/or unrecovered wounds on the face.
- Subjects with skin disease, such as dermatitis and acne, or scar on the face, which the investigator judges can affect the evaluation of treatment effectiveness or safety of the test subject.
- Subjects who took anticoagulant drugs (e.g., aspirin, nonsteroidal anti-inflammatory drugs, clopidogrel, warfarin, etc.) within two weeks prior to selection; the test subjects who are menstruating can avoid it by delaying the injection of studied products as needed.
- Subjects who took drugs with muscle relaxation effects (e.g., muscle relaxants, Curare-like substances, anticholinergic drugs, spectinomycin hydrochloride, aminoglycoside-based drugs, polypeptide antibiotics, tetracycline, lincomycin-based drugs, anticholinergics, benzodiazepines and similar drugs, or benzamide drugs) within 4 weeks prior to selection, anticholinergics, benzodiazepines and similar drugs, or benzamide drugs) or are foreseen to use the above drugs during the study period (for 16 weeks after the injection treatment).
- Subjects who have used external medications (e.g., glucocorticoids or tretinoin ointment) on the upper part of the face within 4 weeks prior to the selection or are foreseen to use the drug on the upper part of the face during the study period (for 16 weeks after the injection treatment).
- Subjects who have a history of injecting drugs similar to the study drug within 6 months prior to selection or are foreseen to use during the study period (Botulinum Toxin A type or Botulinum Toxin B type).
- Subjects who have undergone eye shape correction, laser skin transplantation, skin surgery, IPL, frequency surgery, dermabrasion, chemical dermabrasion, or other laser resolution and nonresolution surgery within 6 months prior to selection or are foreseen to do so during the study period.
- Subjects who have had injected hyaluronic acid in the upper part of their face within 12 months prior to selection or plan to do it.
- Subjects who have a history of surgery to remove wrinkles on the face above the eyes or a permanent filling injection.
- Subjects who plan to undergo a wrinkle removal surgery on their face during the study period, an injection filling of soft tissue for wrinkle removal, or other facial plastic surgeries.
- Subjects whom the investigator judges to be unsuitable to participate in this study
