At Between the Lines Aesthetics, we believe in empowering our clients with accurate, evidence-based information about the treatments we offer. Botox (onabotulinumtoxinA) remains the most performed cosmetic procedure worldwide—and it’s easy to see why. With predictable results, high patient satisfaction, and minimal downtime, it’s no wonder millions turn to Botox for a refreshed, youthful look. [1]
What Is Botox?
Botox works by temporarily blocking nerve signals to specific facial muscles, causing them to relax and smoothing the skin above. [2] The neurotoxin binds to motor nerve terminals, inhibiting the release of acetylcholine, which results in localized muscle relaxation and reduced appearance of wrinkles. In simple terms: it softens lines without surgery, giving you a naturally rejuvenated look. [2]
FDA-Approved Cosmetic Uses
Botox Cosmetic is FDA-approved to treat:
Glabellar lines (frown lines between the eyebrows)
Lateral canthal lines (crow’s feet)
Forehead lines
Platysma bands (neck bands) [2]
These are dynamic wrinkles—lines that appear when you move your face. Dynamic wrinkles respond better to Botox than static lines, which are visible even at rest. [1]
Botox is versatile, safe, and effective for a wide variety of patients, regardless of age, gender, race, or severity of facial lines. [3]
What to Expect: Timeline and Results
Most patients notice results within two weeks, with peak effects appearing between 30 and 60 days post-injection. [4] Effects usually last three to four months. Clinical studies show that the median duration of response for glabellar lines is 120 days, and repeated treatments can enhance results over time. [4]
Patient satisfaction is high: more than 80% report being pleased with their results through day 60, with many feeling they look up to four years younger at weeks 4 and 12 compared to baseline. [4]
Safety Profile
Botox has been extensively studied and demonstrates an excellent safety profile with low risk of immune reaction. [3] Common side effects vary by area:
Glabellar lines: Eyelid drooping in ~3%
Crow’s feet: Eyelid swelling in ~1%
Forehead lines: Headache (9%) and brow drooping (2%) [2]
Minor bruising at injection sites is possible. Most side effects are transient, occurring within the first week. Rare complications like temporary eyelid or brow drooping are technique-dependent and become less likely with experienced injectors. [1]
Who Should Avoid Botox?
Botox is not recommended for individuals with:
Allergies to botulinum toxin
Neuromuscular disorders (e.g., myasthenia gravis, Lambert-Eaton syndrome)
Keloidal scarring
Body dysmorphic disorder [1][2]
Patients with pre-existing neuromuscular conditions face increased risk of generalized muscle weakness and respiratory complications.
