Neurotoxins 101: Understanding Botox®, Dysport®, and More

Demystifying neurotoxin treatments: how they work, what to expect during treatment, and how to achieve natural-looking results that enhance your appearance without looking "frozen."
What Are Neurotoxins?
Neurotoxins used in aesthetic medicine are purified proteins derived from Clostridium botulinum bacteria. When injected in very small, controlled amounts, these proteins temporarily block the nerve signals that cause muscle contractions. This relaxation of targeted muscles reduces the appearance of dynamic wrinkles—those formed by repeated facial expressions.
The most common neurotoxin brands include:
- Botox® (onabotulinumtoxinA) - The original and most recognized brand
- Dysport® (abobotulinumtoxinA) - Known for its quick onset and natural spread
- Xeomin® (incobotulinumtoxinA) - A highly purified formulation without accessory proteins
- Jeuveau® (prabotulinumtoxinA) - A newer option sometimes called "Newtox"
While these products all work similarly, they have subtle differences in formulation, onset time, spread, and duration that can make one more suitable than another for specific patients or treatment areas.
How Neurotoxins Work
To understand neurotoxins, it helps to understand how wrinkles form. Dynamic wrinkles develop from thousands of repeated muscle movements over time—smiling, frowning, squinting, and other expressions. Eventually, these repeated movements create permanent lines even when your face is at rest.
Neurotoxins work by temporarily blocking the release of acetylcholine, a neurotransmitter that signals muscles to contract. When strategically injected into specific facial muscles, neurotoxins reduce their activity, allowing the skin above to relax and smooth out.
Importantly, neurotoxins don't affect sensory nerves, so you maintain normal feeling in the treated areas. They also don't affect your ability to express emotions—when properly administered, they reduce wrinkles while preserving natural facial movement.
Common Treatment Areas
Neurotoxins are FDA-approved for several cosmetic concerns, and they're also used "off-label" for additional applications based on extensive clinical experience. Common treatment areas include:
- Glabellar lines (the "11s" between eyebrows) - Caused by the corrugator and procerus muscles
- Forehead lines - Horizontal lines that appear when raising eyebrows
- Crow's feet - Lines radiating from the corners of the eyes when smiling
- Bunny lines - Wrinkles that form on the nose when smiling
- Lip lines - Vertical lines around the mouth
- Downturned mouth corners - For a subtle lift of the mouth corners
- Chin dimpling ("orange peel" texture)
- Neck bands - Vertical platysmal bands
- Masseter muscles - For jawline slimming and TMJ relief
The Treatment Experience
If you're considering neurotoxin treatment, here's what to expect:
Before Treatment
Preparation helps ensure optimal results and minimize potential side effects:
- Avoid blood thinners like aspirin, ibuprofen, fish oil, and vitamin E for 1-2 weeks before treatment (with your doctor's approval)
- Avoid alcohol for 24-48 hours before treatment
- Come to your appointment with clean skin, free of makeup
- Inform your provider about any medical conditions, medications, or previous cosmetic treatments
During Treatment
The treatment process is quick and relatively comfortable:
- Your provider will cleanse the treatment areas
- You may receive a topical numbing cream for comfort, though many patients find it unnecessary
- Your provider will ask you to make various expressions to identify the precise injection points
- The neurotoxin is injected using a very fine needle
- The entire process typically takes 10-20 minutes
Most patients describe the sensation as a brief pinch or sting. Discomfort is minimal and temporary.
After Treatment
Post-treatment care is simple but important:
- Remain upright for 4 hours after treatment
- Avoid touching or massaging the treated areas for 24 hours
- Skip strenuous exercise, saunas, and hot showers for 24 hours
- Avoid facials and other facial treatments for 1-2 weeks
- Gently exercise the treated muscles by making expressions for the first hour after treatment (this may help the neurotoxin bind more effectively)
Timeline of Results
Understanding the timeline helps set realistic expectations:
- Initial effects: You may notice some changes within 24-48 hours, particularly with Dysport®, which tends to have a faster onset
- Full results: Maximum effect typically appears within 7-14 days
- Duration: Results generally last 3-4 months for first-time users, and may last longer (4-6 months) with regular treatments
- Maintenance: Follow-up treatments are recommended as movement returns to maintain results
The Art of Natural Results
The key to successful neurotoxin treatment is achieving a refreshed, natural appearance—not a frozen or expressionless look. This requires:
- Proper dosing: Often, less is more. Conservative dosing preserves some movement while reducing wrinkles
- Strategic placement: Precise injection points target problematic muscles while preserving essential movement
- Customized approach: Treatment should be tailored to your unique facial anatomy, muscle strength, and aesthetic goals
- Balance: Treating complementary areas creates harmony and prevents compensatory wrinkles

Comparing Neurotoxin Brands
| Brand | Onset | Spread | Duration | Unique Features |
|---|---|---|---|---|
| Botox® | 3-5 days | Moderate | 3-4 months | Most studied, predictable results |
| Dysport® | 1-3 days | More diffusion | 3-4 months | Faster onset, good for larger areas |
| Xeomin® | 3-5 days | Limited | 3-4 months | No accessory proteins, may reduce antibody resistance |
| Jeuveau® | 2-4 days | Similar to Botox® | 3-4 months | Newer option, modern manufacturing |
The "best" neurotoxin varies by individual. Your provider will recommend the most appropriate option based on your treatment areas, desired results, and previous experiences.
Potential Side Effects
When administered by qualified professionals, neurotoxin treatments are very safe with minimal side effects. Possible temporary effects include:
- Mild redness, swelling, or bruising at injection sites
- Headache (usually mild and brief)
- Slight discomfort at injection sites
Rare but possible side effects include:
- Temporary drooping of the eyelid or eyebrow
- Asymmetry or uneven results
- Flu-like symptoms (very rare)
Most side effects, if they occur, resolve within days to weeks. Choosing an experienced, qualified provider significantly reduces these risks.
