Understanding the Basics
What is Botox?
Botox (onabotulinumtoxinA) is manufactured by Allergan and has been the gold standard in cosmetic medicine for over two decades. In Australia, it received TGA approval for cosmetic use in 2002, though it had been used medically since the 1990s.
Key characteristics:
- Larger molecular weight (900 kDa)
- More localised effect
- Established safety profile
- Extensive clinical research
- Premium pricing position
What is Dysport?
Dysport (abobotulinumtoxinA) is manufactured by Galderma and entered the Australian market as a competitor to Botox. It received TGA approval in 2009 and has gained significant market share.
Key characteristics:
- Smaller molecular weight (500-700 kDa)
- Greater diffusion area
- Faster onset of action
- More affordable per unit
- Growing clinical evidence
Molecular Differences and Clinical Implications
Protein Complex Size
The fundamental difference between Botox and Dysport lies in their molecular structure:
Botox:
- Larger protein complex (900 kDa)
- Contains more protective proteins
- Less likely to spread beyond injection site
- More predictable placement
Dysport:
- Smaller protein complex (500-700 kDa)
- Fewer protective proteins
- Greater potential for spread
- Requires adjusted injection technique
Clinical Significance
These molecular differences translate to practical implications:
- Precision requirements: Botox's limited spread makes it ideal for areas requiring precision
- Coverage efficiency: Dysport's spread can be advantageous for larger treatment areas
- Dosing considerations: Different molecular sizes require different unit calculations
- Injection technique: Practitioners must adjust their approach based on product choice
Onset of Action: Speed Matters
Dysport's Faster Results
Clinical studies consistently show Dysport works faster:
- 24 hours: Some patients notice initial effects
- 48-72 hours: Majority see visible improvement
- 5-7 days: Full effect achieved
Botox's Gradual Onset
Botox follows a more traditional timeline:
- 2-3 days: Initial muscle relaxation begins
- 5-7 days: Noticeable wrinkle reduction
- 10-14 days: Maximum effect reached
Why the Difference?
The smaller molecular size of Dysport allows:
- Faster tissue penetration
- Quicker binding to nerve terminals
- More rapid muscle relaxation
- Earlier visible results
Duration and Longevity
Similar Overall Duration
Both products typically last 3-4 months, but individual variation exists:
Factors affecting duration:
- Injection technique
- Dosage accuracy
- Individual metabolism
- Muscle strength
- Treatment frequency
- Lifestyle factors
Building Longevity
Regular treatments can extend duration:
- First treatment: 2.5-3 months
- After 3 treatments: 3-4 months
- After 1 year: 4-5 months possible
- Long-term users: Up to 6 months
Spread and Diffusion Patterns
Understanding Spread Radius
Botox:
- Approximately 1cm diffusion radius
- Stays close to injection point
- Ideal for targeted treatment
- Lower risk of affecting unintended muscles
Dysport:
- 2-3cm diffusion radius
- Broader area coverage
- Fewer injection points needed
- Requires careful placement
Clinical Applications
Best uses for Botox's precision:
- Crow's feet (close to eyes)
- Bunny lines (nose)
- Lip flip
- Gummy smile
- Brow lift
Best uses for Dysport's spread:
- Forehead lines
- Glabellar lines (frown)
- Neck bands
- Armpit sweating
- Large muscle groups
Dosing and Unit Conversion
Not Interchangeable
Units of Botox and Dysport are not equivalent:
Conversion ratio:
- 1 unit Botox = 2.5-3 units Dysport
- Some practitioners use 1:2.5
- Others prefer 1:3
- Individual variation exists
Typical Dosing Examples
| Treatment Area | Botox Units | Dysport Units | Injection Points |
|---|---|---|---|
| Forehead | 10-20 | 25-60 | 4-8 |
| Frown Lines | 20-30 | 50-90 | 5 |
| Crow's Feet | 12-20 per side | 30-60 per side | 3-4 per side |
| Brow Lift | 2-5 per side | 5-15 per side | 1-2 per side |
| Bunny Lines | 4-8 | 10-24 | 2-4 |
Cost Analysis for Australian Patients

Frequently Asked Questions
Can I switch between Botox and Dysport?
Yes, you can switch between products. Many patients alternate to prevent resistance or find their preferred option. Wait until the previous treatment wears off (3-4 months) before switching. Your practitioner will adjust dosing accordingly.
Is one product safer than the other?
Both Botox and Dysport have excellent safety profiles when administered by qualified practitioners. Both are TGA-approved in Australia. Botox has longer historical data, while Dysport has proven equally safe in clinical use since 2009.
Why do some clinics only offer one product?
Clinics may choose one product due to: supplier relationships, staff training requirements, inventory management, pricing agreements, or practitioner preference. Larger clinics typically offer both options to accommodate patient preferences.
Will I need more appointments with Dysport?
No, both products typically last 3-4 months, requiring similar appointment frequency. Some patients report Dysport wearing off slightly faster (2-3 weeks earlier), while others find no difference in duration.
Can I get Botox and Dysport in the same treatment?
While technically possible, most practitioners avoid mixing products in the same session to maintain predictable results and simplify any troubleshooting if needed. Different areas could theoretically receive different products, but this is uncommon.
