Neurotoxin Injections: Everything to Know Before You Book
A complete, science-backed guide to neurotoxin injections—what they treat, how they work, and what to expect before, during, and after treatment.
Neurotoxin injections are one of the most popular and accessible non-surgical cosmetic treatments. Whether you’re curious about softening frown lines, combating crow’s feet, or exploring off-label uses, understanding the science, safety, and expectations around these treatments is essential. This guide covers everything you need to know, including the science behind neurotoxins, their cosmetic and medical uses, treatment timelines, recovery, potential side effects, and critical FAQs.
What Are Neurotoxins?
Neurotoxins—also called neuromodulators—are injectable medications derived from purified botulinum toxin type A. Widely known by brand names like Botox, Dysport, Xeomin, Jeuveau, and Daxxify, they have become a mainstay of modern cosmetic dermatology. Neurotoxins are injected into targeted muscles to temporarily relax them, which reduces the appearance of expression lines and wrinkles.
- Mechanism: Neurotoxins work by interrupting the signals from nerves to muscles, thereby reducing or preventing muscle movement at the injection site. This results in smoother skin and softened wrinkles.
- Temporary results: The effects generally last from three to six months, after which muscle function returns and wrinkles may gradually reappear.
How Do Neurotoxin Injections Work?
Neurotoxin injections target muscles beneath the skin responsible for causing dynamic wrinkles—wrinkles formed by repetitive facial expressions like smiling, frowning, or squinting. When injected, the toxin binds to the nerve endings, blocking the release of a chemical messenger (acetylcholine), which prevents muscles from contracting as strongly.
- Reduces movement: Less contraction means less folding of the skin and thus fewer wrinkles.
- Can range from softening to full paralysis: Depending on the dosage and area, neurotoxins can either simply relax wrinkles or fully paralyze targeted muscles for a more dramatic smoothing effect.
- Gradual wearing off: As the toxin’s effects fade, muscle action returns, so regular maintenance is required for sustained results.
The Different Types of Injectable Neurotoxins
The U.S. Food and Drug Administration (FDA) has approved several formulations of botulinum toxin type A, each with subtle differences. Understanding each may help you and your provider choose the best fit for your needs.
| Brand Name | Key Features | Unique Considerations |
|---|---|---|
| Botox | The classic standard; broadest research and longest track record. | Most widely recognized and used for both cosmetic and medical purposes. |
| Dysport | Diffuses somewhat more, may take effect faster for some patients. | Often used for larger areas like forehead. |
| Xeomin | Free of accessory proteins (“naked” formula). | Less likely to cause immune reactions/sensitization. |
| Jeuveau | Newest entrant; similar profile to Botox. | Sometimes marketed as “Newtox.” |
| Daxxify | Uses a stabilizing peptide for longer-lasting effects. | Can last up to 6 months for some patients. |
| Letybo | Newest FDA-approval; broader availability expected soon. | Still rolling out in the U.S. market. |
What Can Neurotoxin Injections Treat?
Neurotoxins are best known for smoothing wrinkles, but their approved and off-label uses are impressively diverse—helping not just cosmetic but also medical conditions. Here are the most common treatment areas:
- Forehead lines – Softens horizontal creases from repeated eyebrow-raising.
- Glabellar lines (“11’s”) – Targets frown lines between the brows.
- Crow’s feet – Smooths fine lines at the outer corners of the eyes.
- Eyebrow lift – Slight lifting for droopy brows.
- Bunny lines – Treats wrinkles on the nose when scrunching.
- Chin dimpling – Softens texture irregularity (orange-peel appearance).
- Lip flip – Subtle enhancement of the upper lip by relaxing the surrounding muscle.
- Platysmal bands (neck) – Reduces visible neck bands by relaxing neck muscles.
- Jaw slimming (masseter reduction) – Temporarily slims the lower face for those with strong jaw muscles.
- Gummy smile correction – Lessens show of gum tissue when smiling.

Off-Label and Medical Uses
- Hyperhidrosis (excessive sweating) – Underarms, palms, and soles.
- Chronic migraines
- Muscle spasticity/stiffness – Such as in upper limbs or neck (cervical dystonia).
- Eye twitching (blepharospasm)
- Overactive bladder
- Excessive salivation
Note: Many of these areas constitute “off-label” use, meaning the application isn’t specifically FDA-approved for that area or indication, though experienced practitioners commonly use these techniques when medically appropriate.
What to Expect During a Neurotoxin Appointment
Here’s a typical breakdown of what happens when you book a neurotoxin treatment:
- Consultation: A thorough discussion of your goals, medical history, and suitability for neurotoxin injections. Your provider will evaluate your facial structure, skin type, and muscle activity while explaining expected outcomes and potential risks.
- Preparation: The treatment area is cleaned. Topical numbing isn’t usually necessary, as most people find the injections surprisingly tolerable.
- Injection: Using a small needle, multiple tiny injections are administered to precise muscles. The number of units and injection sites depend on the area(s) treated and the desired result.
- Aftercare: Instructions may include avoiding strenuous activity and not rubbing the injection sites for a few hours. Minor redness or pinprick marks may occur but typically fade quickly.
When Will You See Results? How Long Do They Last?
- Onset: Effects usually start becoming visible within 2 to 5 days, with peak results appearing in about 2 weeks.
- Duration: Most neurotoxins last 3–4 months. Some newer formulations (like Daxxify) may last up to 6 months for certain patients.
- Maintenance: To maintain smoothness, schedule repeat treatments as the effects start to wear off. The timing depends on metabolism, lifestyle, dosage, and area treated.
Am I a Good Candidate for Neurotoxin Injections?
Most healthy adults who want to reduce dynamic facial wrinkles are good candidates for neurotoxins. However, there are exceptions and important factors to consider:
- Ideal candidates: Individuals with mild to moderate dynamic wrinkles (lines caused by muscle movement), seeking nonsurgical, temporary results.
- Non-ideal candidates: Pregnant or breastfeeding individuals, those with certain neuromuscular disorders (e.g., myasthenia gravis), or allergies to any ingredients in the product.
- Consult a provider: Only a qualified injector can determine if neurotoxins are right for your needs and medical status.
Potential Side Effects and Safety Considerations
While neurotoxin injections are widely considered safe when administered by trained, experienced professionals, they still carry some risks and possible side effects:
- Very common: Slight redness, swelling, or bruising at injection sites.
- Less common: Headache, heaviness or tightness in the area, mild tenderness.
- Rare but possible:
- Drooping eyelid or brow (ptosis)
- Uneven results or asymmetry
- ‘Frozen’ look if overdosed or improperly placed
- Migration of the toxin, affecting nearby muscles
- Allergic reaction (extremely rare)
Important: Always choose a board-certified dermatologist, plastic surgeon, or facial aesthetics physician for your treatment. Inexpert injections are the number one cause of complications.
Neurotoxin Vs. Filler: What’s the Difference?
| Treatment | Neurotoxin | Filler |
|---|---|---|

| Active Ingredients | Botulinum toxin type A | Hyaluronic acid or other gel-like substances |
| Duration | 3–6 months | 6 months–2 years, depending on product/area |
| Use cases | Forehead, crow’s feet, frown lines, bunny lines, lip flip, etc. | Lips, cheeks, nasolabial folds, under eyes, jawline, hands |
Frequently Asked Questions
How do I prepare for a neurotoxin appointment?
Avoid blood thinners (such as aspirin and ibuprofen), alcohol, and vitamin E for several days prior to reduce risk of bruising, unless your doctor directs otherwise. Arrive with a clean face and discuss your full medical history with your provider.
Does getting injected hurt?
The procedure uses very fine needles, and most people rate the discomfort as minor—a quick pinch or stinging sensation. No anesthesia is needed, but numbing cream may be used if you’re sensitive.
Can neurotoxin injections make me look ‘frozen’?
In the hands of a skilled injector, results should appear natural and allow for normal facial expression. The ‘frozen look’ is usually due to excessive doses or injections placed in the wrong muscles.
Do I need to do anything after my appointment?
- Do not lie down, vigorously rub, or massage treated areas for at least 4 hours.
- Avoid strenuous activity, saunas, and hot baths for 24 hours.
- You can resume makeup and normal activities usually right away, unless otherwise directed by your provider.
How often will I need touch-ups?
Most people repeat treatments every 3 to 4 months to maintain optimal smoothing. Longer-lasting products may extend the interval.
Are neurotoxin injections reversible?
The effects are temporary and cannot be ‘reversed’ immediately. If you dislike your results or experience a complication, you’ll need to wait for the toxin to naturally wear off—usually within several months.
Are there any long-term risks?
Current research shows neurotoxin injections are safe over repeated use for most healthy adults. Rarely, long-term use can result in mild muscle weakening or resistance to the toxin, but these outcomes are uncommon with proper administration.
Tips for Best Results
- Choose your injector carefully. Board-certified dermatologists, plastic surgeons, or specialized injectors with a deep understanding of facial anatomy are safest and most effective.
- Be honest about your goals and concerns. Communication is key to getting natural-looking results that suit your unique face.
- Practice regular aftercare. Following post-procedure instructions minimizes side effects and helps you achieve a smooth, even finish.
- Commit to maintenance. Neurotoxin injections are temporary—regular treatments keep results fresh.
Consulting the Experts
Modern neurotoxin treatments are incredibly customizable and effective, but the best results happen when you work with expert professionals. Board-certified dermatologists can recommend the right product, dosing, and treatment areas to help you achieve your cosmetic goals—and keep you safe in the process.
Key Takeaways
- Neurotoxins like Botox, Dysport, Xeomin, Jeuveau, Daxxify, and others can smooth wrinkles, treat medical conditions, and offer surprisingly versatile results.
