Understanding Neurotoxin Units: Your Dosage Guide for Botox, Dysport, & Xeomin in Irvine
Clarity You Can Trust When It Comes to Units
If you’ve ever wondered how many "units" of Botox you need—or what that even means—you’re not alone. At Plump Medical Spa, we prioritize transparency, education, and doctor-led precision in every treatment. Whether you're in Irvine, Orange County, or nearby cities like Tustin, Costa Mesa, Santa Ana, or Newport Beach, we take time to explain the science behind your beauty.
Botox, Dysport & Xeomin: What’s the Difference in Units?
Botox: Standard unit-based neurotoxin. Most treatment areas need between 10–25 units.
Dysport: Measured differently—1 Botox unit = ~2.5 Dysport units.
Xeomin: Unit-for-unit match with Botox, but contains no complexing proteins.
The number of units required depends on:
Treatment area (forehead, frown lines, crow’s feet, jawline, etc.)
Muscle strength
Individual anatomy and aesthetic goals
At Plump, every dosage is personalized to your face, your movement, your goals.
Doctor-Only Injections Make the Difference
At our Irvine-adjacent location in Santa Ana, Dr. Amir Mortazavi, MD performs every neurotoxin injection personally. This ensures not only optimal safety but also artistry in dosing that aligns with your natural expressions.
We believe that results should never be cookie-cutter—and neither should your dose.
What to Expect with Your Dosage
First-time patients typically start conservatively to assess muscle response.
Maintenance patients may need touch-ups every 3–4 months.
Larger muscles, like the masseter for jaw slimming, may require 30–50 units per side.
We always consult with you beforehand and outline dosage before treatment.
