Core Dosing Principles
Foundational guidelines for safe and effective treatment
Start Conservative
Begin with lower doses and titrate up based on response
- •First-time patients: use 70-80% of standard doses
- •You can always add more at follow-up
- •Over-treatment requires waiting 3-4 months to resolve
- •Patient satisfaction is higher with gradual optimization
Individualize Treatment
No two patients are alike. Customize based on assessment
- •Assess muscle mass and strength before dosing
- •Consider patient goals: natural vs. frozen
- •Account for treatment history and metabolism
- •Adjust for age, gender, and lifestyle factors
Maintain Balance
Treat complementary areas together for natural results
- •Always pair forehead with glabella treatment
- •Consider full face harmony, not isolated areas
- •Avoid creating compensatory muscle recruitment
- •Match left and right side dosing for symmetry
Document Everything
Detailed records improve future treatment accuracy
- •Record exact units per injection point
- •Note dilution and product lot numbers
- •Photograph before and after (same lighting/angle)
- •Track patient response at follow-up visits
Dosing by Patient Type
Customize dosing based on patient characteristics and history
Dosing by Treatment Goal
Adjust doses based on the desired outcome
Natural Look (Baby Botox)
Subtle softening while maintaining expression
Standard Cosmetic
Balance of smoothing and natural movement
Maximum Correction
Complete smoothing with minimal movement
Preventative
Stop wrinkles before they form
Product-Specific Dosing
Compare dosing across different neurotoxin brands
Botox (onabotulinumtoxinA)
Allergan
Gold standard. Most studied product. Reference for all conversions.
Dosage Notes
- •FDA approved doses: Glabella 20U, Crow's feet 24U (12 per side)
- •Forehead not FDA-approved but commonly 10-20U
- •Cosmetic total typically 40-60U per session
Treatment Timing & Scheduling
When to treat and retreat for optimal results
Initial Treatment Series
Build consistent results, establish baseline response
- •First 3 treatments at regular intervals
- •Assess and adjust dose each visit
- •Document optimal dose for future reference
Maintenance Phase
Once optimal dose established, can extend intervals
- •Schedule before full effect wears off
- •Consistent treatment prevents deep line formation
- •Adjust interval based on individual metabolism
Touch-Up Visit
Peak effect time, best for assessing and adjusting
- •Evaluate results at peak effect
- •Add small amounts to under-treated areas
- •Don't exceed 10-20% of original dose
Special Event Timing
Allow time for full effect and any bruising to resolve
- •Not less than 2 weeks before important events
- •First-time patients need 3-4 weeks buffer
- •Account for potential bruising (7-10 days)
Early Retreatment
Prevent antibody formation, allow full wear-off
- •Never retreat full doses before 3 months
- •Small touch-ups at 2 weeks are acceptable
- •Frequent treatments may cause resistance
Dose Adjustment Scenarios
How to handle common situations requiring dose changes
Common Dosing Mistakes
Errors to avoid for better patient outcomes
Treating forehead without glabella
Consequence: Brow ptosis (heavy, drooping brow)
Prevention: Always pair forehead and glabella treatments
Too much forehead Botox
Consequence: Frozen, surprised, or heavy look
Prevention: Keep forehead doses low (10-20U for most patients)
Using same dose for all patients
Consequence: Over-treatment or under-treatment
Prevention: Assess muscle mass and customize each treatment
Not accounting for gender differences
Consequence: Men under-treated, women over-treated
Prevention: Increase male doses by 25-50%
Injecting too close to orbital rim
Consequence: Eyelid ptosis or diplopia
Prevention: Stay at least 1cm above orbital rim
Overtreating first-time patients
Consequence: Unhappy patient, must wait months to resolve
Prevention: Start with 70-80% of standard doses
Not scheduling follow-up
Consequence: Missed opportunity to optimize and build trust
Prevention: Always book 2-week follow-up for new patients
Treating too frequently
Consequence: Potential antibody formation, resistance
Prevention: Maintain minimum 3-month interval for full treatments
Wrong Dysport conversion
Consequence: Significant over or under-treatment
Prevention: Use 2.5-3:1 ratio (Dysport:Botox)
Ignoring asymmetry
Consequence: Uneven results
Prevention: Assess and document facial asymmetry before treatment
