Clinical Assessment of Neurotoxin Injection Botulinum for Treatment of Dynamic Facial Forehead and Frown Wrinkles

The aim of this study is to clinically evaluate the effectiveness and safety of Botox in treating facial wrinkles, specifically horizontal forehead lines and frown lines.The evaluation included the overall quality of life, patient satisfaction, the impact on self-esteem after treatment.Botulinum toxin injection (Botox) is a frequently performed cosmetic procedure for treating facial wrinkles worldwide1.Botox, a neurotoxic protein produced by Clostridium botulinum bacteria, works by temporarily blocking the release of acetylcholine.Treatment of frown lines and crow's feet, which are the cosmetic indications approved by the U.S. Food and Drug Administration, and horizontal forehead lines, offers predictable results, has few adverse effects, and is associated with high patient satisfaction.Dynamic wrinkles, seen during muscle contraction, yield more dramatic results than static wrinkles, which are visible at rest.This was a singlecenter prospective study involving 20 healthy female participants aged 22-35 years.Inclusion criteria required that participants had not received Botox injections within the 6 months prior to the project's commencement.Exclusion criteria included a history of stomatognathic pain, facial, or neck surgery; chronic diseases (e.g., thyroid disease, systemic lupus erythematosus, immunodeficiency disorders); or any conditions that could potentially interfere with study outcomes.Patients selected with dynamic wrinkles demonstrate the most dramatic improvements from botulinum toxin injection and are ideal candidates for treatment.Patients with static wrinkles that are visible at rest are also candidates, but results are slower, and patients may require two or three consecutive Procedures.reduction of dynamic frown lines one month after treatment of the glabellar complex muscles with 20 units of on a botulinum toxin.Return of muscle function is gradual, typically three to four months after treatment.Subsequent treatment is advised when muscle contraction is visible in the treatment area before facial lines return to their pretreatment appearance.After multiple treatments, botulinum toxin effects may be prolonged and, for some patients, treatment intervals can be extended beyond three to four months.
