Neurotoxins Explained: What They Are and How They Work
Neurotoxins are one of the most widely used ingredients in aesthetic medicine. Most people know them as the active ingredient in anti-wrinkle treatments like Botox, but many are unsure how they actually work or what the word really means.
At The Aesthetics Doctor, Dr Ahmed uses medical-grade botulinum toxin to treat everything from fine lines to jaw tension and excessive sweating. This treatment works by calming targeted muscles to smooth expression lines or relieve unwanted muscle activity. In this blog, we explain what neurotoxins are, how they work, and what you can expect from treatment.
What Is a Neurotoxin?
A neurotoxin is a substance that affects how nerves communicate with muscles. In aesthetic treatments, the most common neurotoxin used is botulinum toxin type A, a purified protein derived from the bacterium Clostridium botulinum.
When used in controlled, medical doses, this protein can safely reduce muscle activity in specific areas of the face or body. This makes it useful for:
- Softening dynamic wrinkles
- Creating facial symmetry
- Treating conditions like teeth grinding or excessive sweating
Despite the scientific name, neurotoxins used in aesthetics are highly regulated and have a long track record of safe, effective use.
How Do Neurotoxins Work?
Every time you frown, smile or squint, tiny facial muscles contract. Over time, these repeated movements lead to expression lines. Neurotoxins work by blocking the signal from the nerve to the muscle, preventing the muscle from contracting as strongly.
When injected precisely into targeted muscles, neurotoxins:
• Reduce unwanted movement
• Soften the appearance of fine lines and creases
• Allow the skin to recover and appear smoother over time
Neurotoxins work in harmony with your facial anatomy, relaxing specific muscles to ease expression lines while preserving natural movement.
Where Are Neurotoxins Used in Aesthetics?
Neurotoxins can be used across multiple areas of the face and neck, depending on your goals. Common treatment areas include:
• Forehead lines
• Bunny lines around the nose
• Chin dimpling or “orange peel” texture
• Jaw slimming or tension relief
• Neck bands or sagging
• Lip flip enhancement
Each treatment is tailored to your individual facial anatomy, ensuring the right muscles are treated with the correct dose for natural-looking results.
Medical Uses of Neurotoxins
Neurotoxins are not limited to cosmetic treatments. They are also used in medical practice to relieve symptoms caused by overactive or tight muscles. These include:
• Bruxism (teeth grinding): Botox is injected into the masseter to reduce jaw tension
• Migraines: Small amounts are placed in the head and neck muscles to help reduce headache frequency
• Hyperhidrosis (excessive sweating): Injections block sweat gland activity in areas like the underarms or hands
• Eye twitching or muscle spasms: Used in neurological medicine for relief from involuntary movements
At The Aesthetics Doctor, Dr Ahmed uses the same careful approach whether the treatment is cosmetic or medical, always prioritising patient comfort and safety.
How Long Do Neurotoxin Results Last?
The effects of neurotoxins are temporary. You can usually expect:
- Visible results within 3 to 10 days
- Peak results around 2 weeks
- Gradual return of movement by 3 to 4 months
Maintenance treatments are typically recommended every 3 to 4 months to keep the results consistent. Over time, with repeated treatments, some patients notice the effects lasting a little longer as the muscle becomes less overactive.
Are Neurotoxins Safe?
Yes. Botulinum toxin has been used in medicine for decades and is one of the most studied injectables in the world. When administered by a qualified medical professional, it is considered a very safe treatment. Possible side effects are usually mild and temporary. These may include:
• Redness or slight swelling at the injection site
• Mild bruising
• Headache or tenderness for a short time
• Temporary asymmetry in rare cases, which can be corrected
Dr Ahmed carries out a full consultation before treatment to ensure that neurotoxin injections are suitable for your medical history, skin type and concerns.
Will It Freeze My Face?
This is a common concern for first-time patients. When performed correctly, neurotoxin treatment does not freeze your face. The goal is to soften harsh lines and overactive muscles without affecting your ability to smile, frown or express emotion.
At The Aesthetics Doctor, we use detailed facial mapping to ensure the right amount of product is placed in exactly the right area. Your expressions will still feel like you, just more refreshed and balanced.
