Neurotoxin Injections
Dynamic wrinkles — the lines that form from years of facial expressions — can make you appear tired, stressed, or older than you feel. Neurotoxin injections offer a proven, minimally invasive solution to smooth these expression lines and restore a more relaxed, refreshed appearance. Whether addressing frown lines, forehead creases, or crow’s feet, these FDA-approved treatments deliver natural-looking results with no downtime and effects that can last three to four months.
Harvard-trained plastic surgeon Dr. Erez Dayan brings exceptional precision and anatomical expertise to every neurotoxin treatment at Avance Plastic Surgery Institute. After completing his residency at the prestigious Harvard Plastic Surgery Program and an aesthetic fellowship at the world-renowned Dallas Plastic Surgery Institute, Dr. Dayan has dedicated his career to achieving naturally elegant results. His deep understanding of facial neuromuscular anatomy — developed through years of surgical training and ongoing research — ensures each injection is placed with precision to achieve balanced, beautiful outcomes.
Expert Injection Technique Makes the Difference
While neurotoxin injections may be widely available, the quality of results varies dramatically based on the injector’s training and experience. The face contains dozens of interconnected muscles, and achieving natural-looking results requires an intricate understanding of how these muscles interact. Too much product or improper placement can create an unnatural, frozen appearance — while precisely targeted injections allow natural expression while smoothing unwanted lines.
“The goal is never to eliminate expression — it’s to soften the lines that make someone look tired or angry while preserving the natural movements that make each face unique,” explains Dr. Dayan. “Understanding the precise anatomy and choosing the right product for each patient is what separates exceptional results from average ones.”
As an author of five books on plastic surgery and a presenter of over 150 lectures nationally and internationally, Dr. Dayan remains at the forefront of aesthetic innovation. His role as a lead investigator for companies including Allergan (the maker of Botox) ensures patients at Avance benefit from the most advanced techniques and protocols available.
Understanding Neurotoxin Treatments
Neurotoxins work by temporarily blocking the nerve signals that cause facial muscles to contract. When these muscles relax, the overlying skin smooths and the wrinkles caused by repetitive movements become less visible. Unlike dermal fillers that add volume, neurotoxins address wrinkles at their source — the muscle activity that creates them.
All FDA-approved neurotoxins contain a form of botulinum toxin type A, but each product has unique characteristics that may make it better suited for certain patients or treatment areas. Dr. Dayan offers multiple neurotoxin options to customize treatment for optimal results.
Botox®
The original and most recognized neurotoxin, Botox has been FDA-approved for cosmetic use since 2002 and has an extensive safety record supported by decades of clinical research. It is highly effective for treating frown lines, forehead wrinkles, and crow’s feet, with results typically appearing within three to five days and lasting three to four months. Beyond cosmetic applications, Botox is also FDA-approved for therapeutic uses including chronic migraine treatment.
Botox treatment areas include:
Dysport®
Dysport is formulated with smaller protein molecules that may spread more readily across treatment areas, making it particularly well-suited for larger zones like the forehead. Many patients notice results within two to three days — slightly faster than other neurotoxins. Dysport is FDA-approved for treating glabellar lines (the “11’s” between the eyebrows) and offers results lasting three to four months.
Xeomin®
Xeomin features a “naked” formulation — purified botulinum toxin without the accessory proteins found in Botox and Dysport. This streamlined formula may reduce the likelihood of developing antibody resistance over time, making Xeomin an excellent choice for long-term treatment or for patients who have noticed diminished response to other neurotoxins. FDA-approved since 2010, Xeomin delivers comparable results for frown lines with effects lasting three to four months.
Jeuveau®
The newest FDA-approved neurotoxin, Jeuveau was developed specifically for aesthetic use and is sometimes called “Newtox.” Its modern manufacturing process creates a highly purified product with reliable, consistent results. FDA-approved for moderate to severe frown lines, Jeuveau offers another excellent option for patients seeking wrinkle reduction with results comparable to established neurotoxins.
Concerns Addressed by Neurotoxin Injections
Neurotoxin treatments are remarkably versatile, addressing a wide range of aesthetic concerns caused by repetitive muscle movement. Common treatment areas include:
- Frown Lines (Glabellar Lines): The vertical “11” lines between the eyebrows that can create an angry or stressed appearance
- Forehead Lines: Horizontal creases across the forehead caused by raising the eyebrows
- Crow’s Feet: Fine lines radiating from the outer corners of the eyes, often called smile lines
- Bunny Lines: Wrinkles that appear on the sides of the nose when scrunching the face
- Neck Bands: Vertical cords on the neck caused by platysma muscle activity
- Lip Lines: Fine vertical lines above and around the lips
Beyond cosmetic applications, neurotoxins also offer therapeutic benefits including treatment for chronic migraines, excessive sweating (hyperhidrosis), and masseter reduction for facial slimming or TMJ relief.
What to Expect During Your Treatment
Neurotoxin injections are among the quickest aesthetic treatments available — often called a “lunchtime procedure” because most sessions take just 10 to 15 minutes. No anesthesia is required, though ice or topical numbing may be applied for comfort. Using an ultra-fine needle, Dr. Dayan or his trained team members deliver precise injections into the targeted muscles.
Most patients describe the sensation as a brief pinch. Immediately following treatment, you may notice small bumps at injection sites that typically resolve within 15 to 30 minutes. There is no downtime — you can return to work and normal activities immediately, though strenuous exercise should be avoided for 24 hours.
Results develop gradually over three to seven days as the neurotoxin takes effect. Full results are typically visible within two weeks and last approximately three to four months. With consistent treatment, many patients find their results last progressively longer as the targeted muscles weaken over time.
Frequently Asked Questions About Neurotoxin Injections
- During your consultation, Dr. Dayan evaluates your facial anatomy, discusses your goals, and recommends the neurotoxin best suited to your needs. Factors include the treatment area, your history with injectables, and whether you've developed any tolerance to previous products.
- Not when administered by an experienced injector. Dr. Dayan uses conservative dosing and precise placement to smooth wrinkles while preserving natural facial movement. The goal is a refreshed appearance — not an expressionless one.
- Most neurotoxin treatments last three to four months. Results may last longer with consistent treatment over time as the targeted muscles gradually weaken. Your individual metabolism and the treatment area also influence duration.
- FDA-approved neurotoxins have extensive safety records supported by decades of clinical use. Side effects are typically mild and temporary, including minor bruising, swelling, or headache. Serious complications are rare when treatment is performed by a qualified provider.
- Yes. Neurotoxins are frequently combined with dermal fillers for comprehensive facial rejuvenation — neurotoxins address dynamic lines while fillers restore lost volume. They also complement laser treatments, chemical peels, and other skin-resurfacing procedures.
- There is no single "right" age. Many patients begin in their late 20s or early 30s as a preventive measure to slow wrinkle formation, while others start later to address established lines. A consultation with Dr. Dayan helps determine the optimal approach for your individual situation.
