Exclusion Criteria:

2. A history of eyelid blepharoplasty or brow lift within the past 5 years
3. A history of facial nerve palsy.
4. Marked facial asymmetry, ptosis, excessive dermatochalasis, deep dermal scarring, or thick sebaceous skin.
5. Any known medical condition that may put the participant at increased risk in regard to exposure to BoNT of any serotype (i.e. myasthenia gravis, Eaton-Lambert syndrome, amyotrophic lateral sclerosis, etc.)
6. Has COVID-19 illness or a known positive SARS-CoV-2 test (Stage 1), or the presence of any other condition (e.g. neuromuscular disorder or other disorder that could interfere with neuromuscular function)
7. Previous treatment with any BoNT serotype for Stage 1 / Step 1 or any recent treatment (within the past 9 months prior to baseline) with any BoNT serotype for Stage 1 / Step 2, Stage 1/Step 3, Stages 2 and 3. Participants treated in earlier Stages/Steps of the study must not be included in any later Stages/Steps.
8. Any prior treatment with permanent fillers in the upper face including the GL, FHL and LCL area.
9. Any prior treatment with long lasting dermal fillers or any permanent procedures in the upper face inclusion the GL area within the past 3 years and/or skin abrasions/resurfacing (whatever the interventional technic used) within the past 5 years, or photo rejuvenation or skin/vascular laser intervention within the 12 months prior to Baseline.
10. Any planned facial cosmetic surgery during the study.
11. Use of concomitant therapy which, in the investigator's opinion, would interfere with the evaluation of the safety or efficacy of the study intervention. Therapy considered necessary for the participant's welfare may be given at the discretion of the investigator.
12. Use of medications that affect neuromuscular transmission, such as curare-like non depolarising agents, lincosamides, polymyxins, anticholinesterases, aminoglycoside antibiotics and systemic retinoids, within the past 30 days prior to baseline are prohibited or a longer washout period of at least five half-lives might be required, as deemed appropriate by the investigator for longer-acting medications. Topical use of for example aminoglycoside medications or topical retinoids on the face apart from the area of injection would be acceptable.
13. Use of any experimental device within 30 days or use of any treatment with an experimental drug within five times the documented terminal half-life of the respective drug or its metabolites or if the halflife is unknown within 30 days prior to the start of the study (prior to Baseline) and during the conduct of the study.
14. Known positive for hepatitis B antigen, or hepatitis C virus antibody, or for human immunodeficiency virus (HIV) or a diagnosis of acquired immunodeficiency syndrome.
15. Clinically diagnosed significant anxiety disorder, or any other significant psychiatric disorder (e.g. depression) that might interfere with the participant's participation in the study
16. An inability to substantially lessen GL and/or horizontal forehead rhytids even by physically spreading them apart as determined by the investigator.

18. A history of drug or alcohol abuse
