What Are Neurotoxins?
October 7, 2025

Neurotoxins are prescription injectables widely used to soften the look of expression lines and help prevent new wrinkles from forming. You may recognize brand names such as Botox, Dysport, Xeomin, and Jeuveau. Each of these products temporarily relaxes specific facial muscles that create lines when you frown, smile, or raise your eyebrows. Unlike dermal fillers, which add volume, neurotoxins address movement-related (dynamic) wrinkles for a smoother, refreshed appearance.
When administered by a licensed, skilled injector, neurotoxin treatments can look subtle and natural. Most patients can still express all normal emotions; the change is that the skin creases less deeply, resulting in a rested, refined look that photographs well and often boosts confidence.
How Neurotoxins Work
Facial movement begins with a signal from a nerve to a muscle. That signal uses a messenger called acetylcholine. Neurotoxin injections are placed precisely into the muscles responsible for wrinkles, where they temporarily block the release of acetylcholine. With fewer contraction signals, the muscle relaxes and the overlying skin smooths.
Why This Helps Both Soften and Prevent Wrinkles
Repeated folding of the skin contributes to line formation over time. By reducing the intensity of those movements, neurotoxins can not only soften the appearance of current lines but also slow the development of deeper creases. Many patients view consistent neurotoxin care as part of a preventive skin aging plan.
Benefits and Who They're For
- Smoother expression lines across the forehead, between the brows, and at the outer eyes.
- Prevention of new or deeper lines with consistent maintenance.
- Quick visits and minimal downtime, often referred to as a lunchtime treatment.
- Natural-looking results when performed by experienced injectors with an aesthetic eye.
Good candidates are generally healthy adults who notice lines that appear with expression or want to prevent deeper creasing. Treatment is not recommended during pregnancy or breastfeeding, and a complete medical history review is essential during your consultation.
Common Treatment Areas
- Forehead lines: horizontal lines when raising the eyebrows.
- Glabellar lines (frown lines or “11s”): vertical lines between the eyebrows.
- Crow's feet: fine lines at the outer corners of the eyes.
- Bunny lines: lines along the bridge of the nose when smiling.
- Lip flip: subtle roll of the upper lip for a slightly fuller look.
- Gummy smile: relaxes upper lip elevation so less gum shows.
- Chin dimpling: softens an uneven, pebbled chin texture.
- Masseter (jawline) treatment: can reduce clenching and create a slimmer lower face appearance.
- Neck bands: helps relax vertical lines in the neck (platysmal bands).
Neurotoxins are also used for certain medical indications such as excessive sweating (hyperhidrosis), jaw tension, and chronic migraines. Ask your provider whether these uses are appropriate in your specific case.
Comparing Brands: Botox, Dysport, Xeomin, and Jeuveau
While outcomes are similar across brands, they may differ slightly in how quickly they take effect, how they diffuse, and how long results last. Your injector will recommend a product based on your anatomy, goals, and treatment area.
What Matters Most
- Injector skill and assessment: dosing, depth, and placement are critical.
- Personal response: some patients observe subtle preference for one brand over time.
- Treatment goals: certain areas or goals may pair better with a specific product.
Many patients achieve great results with any of the four major brands; consistency of care and technique often matter more than the label on the vial.
What to Expect Before, During, and After Treatment
Before Your Appointment
- Avoid alcohol, high-intensity exercise, and blood-thinning supplements for 24 hours if approved by your physician.
- Arrive with clean skin if possible. Makeup can be removed at the clinic if needed.
- Bring your medication list and disclose recent procedures or illnesses.
During Treatment
- Your injector will review your goals, map injection points, and confirm dosing.
- Tiny injections are performed with a very fine needle. Treatment time is commonly 10 to 20 minutes.
- Mild stinging may occur for a few seconds per injection. Numbing options can be discussed in advance.
Aftercare
- Avoid rubbing or massaging treated areas for at least 4 to 6 hours.
- Stay upright and skip strenuous exercise for the remainder of the day.
- Makeup can typically be applied later the same day if skin is not irritated.
Most patients return to normal routines immediately. Minor redness or swelling at injection sites usually resolves quickly.
Results, Longevity, and Maintenance
Early softening often appears in 3 to 5 days, with best results in 10 to 14 days. Effects typically last about 3 to 4 months. Factors influencing longevity include the treatment area, dose, muscle strength, and individual metabolism.
Maintenance Planning
- Most patients schedule visits three to four times per year.
- Preventive schedules can be customized to match your expressions and goals.
- If you pause treatments, lines gradually return to baseline; they do not rebound worse.
Safety, Side Effects, and Contraindications
Neurotoxin injections are widely performed and have a strong safety profile when delivered by qualified professionals in an appropriate clinical setting. Your injector will review risks and obtain informed consent.
Common, Temporary Effects
- Mild redness, swelling, or tenderness at injection points
- Occasional headache
- Small bruises that fade over several days
Less Common Effects
- Transient eyelid or brow heaviness if product spreads to nearby muscles
- Asymmetry that may be adjusted at follow-up
Contraindications include pregnancy, breastfeeding, certain neuromuscular disorders, and allergies to any product component. Share your full medical history so your provider can determine suitability.
