What are Neurotoxins and How Do They Work?

Having wrinkles and fine lines comes with aging. Luckily, there are ways to prevent these unwanted signs without going under the knife.

One of the best ways to maintain smooth and young-looking skin is through injectables. A popular option is neurotoxins which you can have as soon as you see those fine lines forming on your face.

What are Neurotoxins?


Neurotoxins are a type of injectable that eliminates the common signs of aging, such as creases and folds. It works by inhibiting muscle contraction around areas such as forehead lines, brows, and crow’s feet. Neurotoxins are best for removing the lines and preventing their intensity as you age.

How do Neurotoxins work?

The specific type of neurotoxin for facial injections is botulinum toxin. It works by inhibiting the nerve cells that signal specific muscles to contract. Neurotoxins weaken the facial movements that cause fine lines and wrinkles.

Once the muscles weaken, your facial expression becomes less intensified. The toxin molecule works by blocking the connection within one minute after the injection. Results are visible as early as seven days, but you can see the full effect of it after 10 to 14 days.

Regular neurotoxin injections are critical in maintaining a wrinkle-free face. You need to inject neurotoxins after 3-4 months as new nerves begin to connect to the muscles and build activity. Your body will also absorb the neurotoxins after a few months, which regains the communication of the muscles, and your nerves reestablish. If there are no new neurotoxins, lines and wrinkles will resurface.

What is the difference between Neurotoxins and Derma Fillers?

Some people confuse neurotoxins for derma fillers, which is another popular anti-aging option. Derma fillers work by injecting hyaluronic acid, a gel-like substance that provides a naturally relaxed look while compensating for the facial areas that have lost volume. You can use derma fillers to stimulate the natural collagen in your skin, increasing the natural glow of your skin.

Although dermal fillers and neurotoxins may seem identical, they have specific differences that you should consider before deciding what to choose. These are the difference between neurotoxins from dermal fillers:


The process of injecting neurotoxins is similar to Botox. It freezes the muscles that cause wrinkles and other lines to form on the face. The muscle tends to relax during facial expressions, which makes the fine lines and wrinkles unnoticeable.

On the other hand, dermal fillers use hyaluronic acid to plump up areas that have suffered from a loss of volume and fullness. When these areas are filled up, a smooth look begins to appear.

Location of injection

Neurotoxins are typically injected around the eyes and the forehead, where there are heavy muscles for facial expressions. Dermal fillers are placed in the face’s upper and lower half, specifically around the mouth, lips, cheeks, and eyes. These are the areas that usually lose volume as you age.

Length of benefits

The neurotoxin injection results will last up to 3 to 4 months. Meanwhile, dermal fillers last around 10-12 months. How long these will last also varies depending on the type of fillers you use.

At what age should I start receiving neurotoxin injections?

Starting neurotoxin injections depends on age, skin condition, and the goal you want to achieve for your face. Preventing fine lines and wrinkles can start as early as reaching your 20s and up to your 60s.

During your 20s, the facial folds begin to appear on the surface of your skin. It is a perfect time to have neurotoxin injections to minimize the chance of having fine lines and wrinkles etched on your skin.

Treating the muscles even before the wrinkles appear will prevent the formation of lines. People in their 30s and 40s can also have neurotoxin injections as soon as the signs of aging become noticeable.

The sooner one starts with neurotoxins, the sooner you prevent fine lines and creases from becoming prominent as you age. A dermatologist can evaluate your skin’s condition and help you make the safest decision.
