One of the most common misconceptions about Botox is assuming there’s a one-size-fits-all dose. In reality, the number of units required depends on your age, muscle strength, treatment area, and whether the goal is prevention or correction. Here’s a helpful guide to understand what you might need.
Why Does the Number of Units Vary?
- Each muscle has a different size and strength.
- Deeper wrinkles form with age.
- The purpose might be preventive or corrective.
- Some areas need more precision or higher volume.

Suggested Units by Age:
Note: Always confirm with a professional during your consultation.
Common Areas & Estimated Units:
- Forehead: 10 – 20 units
- Frown lines (Glabella): 10 – 25 units
- Crow’s feet: 8 – 15 units per side
- Masseter (bruxism/face slimming): 25 – 50 units per side
