How Many Units of Botox Do I Need? A Guide to Dysport, Letybo & Jeuveau

If you’re considering Botox, one of the most common questions we hear is: “How many units of Botox do I need?”

The answer depends on your facial anatomy, muscle strength, and treatment goals — and it can vary slightly depending on whether Botox®, Dysport®, Letybo®, or Jeuveau® is used.

At The BTX Studio in Cypress, TX, we offer all four FDA-approved neuromodulators and create personalized treatment plans designed for natural, refreshed results.

Botox, Dysport, Letybo & Jeuveau: What’s the Difference?

Botox, Dysport, Letybo, and Jeuveau all work by relaxing targeted facial muscles to reduce wrinkles, but they differ slightly in formulation, spread, and unit measurement.

• Botox®
  The most well-known and widely studied neuromodulator, trusted for decades for precise, consistent results.

• Dysport®
  Formulated to spread a bit more easily, making it a popular choice for larger areas like the forehead. Some clients notice it kicks in slightly faster.

• Letybo®
  A newer FDA-approved option in the U.S., known for its highly refined purification process. It delivers smooth, reliable results and is often a cost-effective alternative while maintaining excellent quality.

• Jeuveau®
  Often referred to as “#Newtox,” Jeuveau is designed specifically for aesthetic use. It performs similarly to Botox and is commonly chosen for cosmetic precision.

Important to know:
Dysport units are measured differently than Botox, Letybo, and Jeuveau units. That’s why Dysport numbers appear higher — it does not mean the treatment is stronger or more expensive. Pricing and effectiveness typically balance out.

These are averages — your exact dosage depends on your facial anatomy, muscle strength, and aesthetic goals.

Factors That Influence How Many Units You’ll Need

While the ranges above give a starting point, here’s what really determines your unique dosage:

• Muscle Strength: Stronger muscles require more units

• Gender: Men often need higher doses

• Wrinkle Depth: Deeper lines require more support

• Desired Look: Soft movement vs. smoother appearance

• Consistency: Consistent treatments may reduce unit needs

Which Neuromodulator Is Right for Me?

All four options deliver natural, refreshed results when dosed correctly. The “best” choice depends on your anatomy, goals, and treatment area.

• Dysport may be ideal for broader areas like the forehead

• Botox, Letybo, or Jeuveau may be preferred for precision areas

• Letybo can be a great option for clients seeking high quality with added value

At The BTX Studio, we’ll guide you toward the option that makes the most sense for you — not a one-size-fits-all approach.
