What’s the Difference — and What Matters Most at The Naderi Center?
Botulinum toxin injections remain the #1 non-surgical cosmetic treatment in the United States. Patients consistently ask:
- Which neurotoxin lasts the longest?
- Why is Botox more expensive in some offices?
- Does Daxxify really last longer?
- Which toxins does The Naderi Center use, and why?
At The Naderi Center medical facility, we believe that educated patients make the best treatment choices. The following guide covers five of the most widely used FDA-approved cosmetic neurotoxins in the United States, while Dr. Shervin Naderi shares his expertise from more than 20 years of work in facial aesthetic treatments.
Five Widely Used FDA-Approved Cosmetic Neurotoxins
Botox Cosmetic
Manufactured by Allergan Aesthetics, Botox Cosmetic (onabotulinumtoxinA) was the first FDA-approved neuromodulator for aesthetic use (2002). It remains the most recognized brand worldwide.
Typical onset: 3–5 days
Average duration: 3–4 months
Botox has the longest track record of any cosmetic neurotoxin, with more than two decades of FDA-approved cosmetic use.
Botox is one of the three neurotoxins our physicians use at The Naderi Center, along with Dysport and Daxxify. It has been in our hands for many years, and our team and our patients appreciate its long safety record and consistent results.
“Botox is predictable, refined, and extremely reliable,” says Dr. Shervin Naderi. “But brand alone doesn’t create natural results. Injection technique does.”
At The Naderi Center, Botox is frequently used for these treatment areas:
- Glabellar or frown lines
- Forehead lines
- Crow’s feet
- Chin dimpling
- Lip flip treatments
- Neck banding
Dysport
Produced by Ipsen, Dysport (abobotulinumtoxinA) was approved in 2009.
Clinically, it performs similarly to Botox, though some patients notice slightly faster onset. It may also diffuse a bit more broadly, which can be beneficial for treating larger muscle groups like the forehead.
Duration: 3–4 months
“Dysport can create beautifully smooth foreheads when dosed precisely,” Dr. Naderi explains. “Understanding diffusion patterns is key.”
Xeomin
Manufactured by Merz Aesthetics, Xeomin (incobotulinumtoxinA) is often called a “naked” toxin because it contains no accessory proteins.
Duration: 3–4 months
Xeomin was FDA-approved for cosmetic use in 2011. It is an effective, well-studied option used by many practices.
Jeuveau
Introduced in 2019 by Evolus, Jeuveau (prabotulinumtoxinA-xvfs) was developed specifically for aesthetic use.
Duration: 3–4 months
Jeuveau is FDA-approved and effective, and it is widely used for frown lines.
“Jeuveau performs well when dosed correctly,” Dr. Naderi says. “As with any toxin, the injector matters more than the brand.”
Want Natural, Refined Results?
It starts with expert technique, precise dosing, and a deep understanding of facial anatomy. Appointments available in Reston, VA and Chevy Chase, MD
Daxxify
Developed by Revance Therapeutics and FDA-approved in 2022, Daxxify (daxibotulinumtoxinA-lanm) is positioned as a longer-lasting neuromodulator.
Why Does Daxxify Last Longer?
Daxxify uses a proprietary peptide stabilizer instead of traditional human serum albumin. Some studies suggest Daxxify can last longer than traditional toxins when it is dosed properly.
However, a critical nuance patients should understand:
Daxxify’s longevity is dose-dependent.
Higher dosing strategies are associated with longer-lasting results. In other words, extended duration often correlates with increased units administered.
“Longevity is tied to dose,” Dr. Naderi explains. “When you increase dose appropriately, duration extends. Daxxify was engineered to maximize that effect.”
Realistic Expectations
Some patients see 5 to 6 months of improvement, but duration varies depending on:
- Muscle strength
- Metabolic rate
- Gender
- Athletic activity
- Injection precision
Because Daxxify may last longer, precision is even more critical.
“If it lasts six months, you want it placed perfectly,” Dr. Naderi notes. “Longevity magnifies both good and bad technique.”
Why Does Botox Pricing Vary Between Offices?
Patients frequently ask why pricing varies dramatically between practices.
Here are the primary reasons:
- Whether pricing is quoted per unit or per area
- Different dilution practices
- Different dosing philosophies
- Injector experience level
At The Naderi Center, dosing is based on:
- Facial anatomy
- Muscle strength
- Gender-specific aesthetics
- Long-term facial harmony
“We don’t treat units — we treat faces,” says Dr. Naderi. “Under-dosing to hit a price point leads to short-lived or incomplete results.”
Which Neurotoxins Does The Naderi Center Use?
At The Naderi Center, our physicians use Botox, Dysport and Daxxify.
Botox and Dysport have been on the market the longest and have the longest history of FDA approval for cosmetic use. That long track record is why they have been in our hands for so many years.
We added Daxxify because it came to market as a longer-acting toxin. Some studies suggest it can last longer when it is dosed properly, which can make it a good option for patients who would like fewer visits.
Xeomin and Jeuveau are also FDA-approved and effective. We simply have the most experience with Botox, Dysport and Daxxify, and that experience is what we bring to every treatment.
What Truly Determines Natural Results?
The most important factor is not the label on the vial.
It is:
- Injector expertise
- Deep anatomical knowledge
- Conservative dosing philosophy
- Aesthetic restraint
Dr. Shervin Naderi has over two decades of exclusive facial plastic surgery experience. That background influences every injection pattern, especially in high-movement areas like the brows and around the mouth.
“The goal is refinement, not freezing,” Dr. Naderi says. “You should look rested — not injected.”
The Takeaway for Patients in Virginia and Maryland
All five of these FDA-approved neurotoxins can produce beautiful, natural results when used correctly:
- Botox Cosmetic
- Dysport
- Xeomin
- Jeuveau
- Daxxify
Botox and Dysport have the longest track record, and Daxxify may last longer when it is dosed properly. Xeomin and Jeuveau are proven, FDA-approved options as well. At The Naderi Center, we use Botox, Dysport and Daxxify, the toxins our physicians have the most experience with.
But at The Naderi Center, the philosophy is simple:
“The injector determines the outcome — not the brand,” Dr. Naderi emphasizes.
Our team will assist you if you are considering neuromodulator treatment and require a consultation which combines precise anatomical knowledge with aesthetic balance.
