What should you do or avoid after a botulinum toxin injection ?

Botulinum toxin injections have become a very popular aesthetic treatment to reduce wrinkles and expression lines and to rejuvenate the face without surgery. Although botulinum toxin injections are considered safe and relatively simple, it is essential to follow the aftercare instructions provided by your doctor to optimize results and minimize the risk of complications. Whether you are a first-time patient or a regular one, understanding what you should and should not do after a botulinum toxin injection is crucial.
In this article, we will explain in detail the aftercare following botulinum toxin injections, what to absolutely avoid, and the best practices to adopt.

Why is it important to follow post–botulinum toxin injection instructions ?

Post-treatment instructions after a botulinum toxin injection are essential to ensure that the product stays in place and works properly in the targeted muscles. Following the right practices can :

Prevent the migration of botulinum toxin to unwanted areas.
Minimize the risk of side effects, such as bruising or swelling.
Optimize results by ensuring the product works effectively to reduce wrinkles and fine lines

Even though botulinum toxin is a non-invasive treatment with minimal downtime, it is essential to follow certain precautions after the injections to avoid any undesirable effects and ensure optimal results.

What you should do after a botulinum toxin injection

Stay upright for the first 4 hours : after a botulinum toxin injection, it is recommended to remain in an upright position for at least 4 hours. This period allows the product to properly bind to the targeted muscles and reduces the risk of migration to other areas of the face. Avoid lying down, bending over, or performing movements that require lowering your head during this time.
Use gentle skincare products : it is essential to continue taking care of your skin after a botulinum toxin injection. Use mild cleansers, fragrance-free moisturizers, and sunscreens to protect your skin.
Follow your doctor’s instructions : your doctor will provide specific recommendations tailored to your case. Follow these instructions carefully.

Misleading instructions

Some post-treatment advice given by certain doctors should be avoided, as they may cause complications.

Apply ice to reduce swelling : applying ice directly to the treated area can cause the product to move. Other muscles may then become affected, leading to the appearance of side effects.
Move your facial muscles : although it is important not to massage or rub the injected areas, it may be helpful to gently move the treated facial muscles, such as frowning, smiling, or raising your eyebrows, for about an hour after the injection. This can help the botulinum toxin integrate into the targeted muscles and improve its effectiveness. In reality, movements can cause the botulinum toxin to shift.
Stay well hydrated : drink plenty of water to help your body recover after the treatment. Good hydration may help minimize potential side effects, such as headaches.
In reality, hydration has no influence on the treatment itself. However, staying well hydrated is important for your overall health.

What should you avoid after a botulinum toxin injection ?

Do not touch, rub, or massage the treated areas : after a botulinum toxin injection, it is essential not to touch, rub, or massage the treated areas for at least 24 hours. Touching the area may cause the botulinum toxin to migrate to non-targeted muscles, which can lead to undesirable results such as facial asymmetry or drooping eyelids.
Avoid exercise for 48 hours : physical activity, including running, weight training, or any activity that increases blood circulation or causes head movement, should be avoided for at least 48 hours after the treatment.
Increased blood circulation could lead to the dispersion of the botulinum toxin, thereby reducing its effectiveness and increasing the risk of bruising.
The heat associated with increased blood flow and head movement can also cause the botulinum toxin to migrate.
No sauna, steam room, or hot baths for 48 hours : hot environments such as saunas, steam rooms, and hot baths should be avoided for at least 48 hours after botulinum toxin injections. Heat can dilate blood vessels and increase the risk of product migration or bruising.
Do not consume alcohol for 24 hours : alcohol can increase the appearance of bruising and swelling by dilating blood vessels. To minimize these risks, avoid drinking alcohol for at least 24 hours before and after your botulinum toxin treatment.
Do not take anti-inflammatory medications without medical advice : certain anti-inflammatory drugs, such as aspirin or ibuprofen, can increase the risk of bleeding and bruising after botulinum toxin injections. Always consult your doctor before taking any medication after your treatment to avoid potential interactions or adverse effects.
Avoid facials and massages for one week : facial treatments, massages, and procedures such as laser, chemical peels, or laser peels should be avoided for at least one week after a botulinum toxin injection. These treatments may cause inflammation, compromise the results, and lead to side effects.
Do not wear tight helmets or hats : accessories that put pressure on the injected area, such as helmets or tight hats, should be avoided for 24 hours after the treatment. Excessive pressure could cause the botulinum toxin to shift.

How long does it take to see the results of botulinum toxin ?

Botulinum toxin works gradually to relax the muscles responsible for wrinkles.
The first results of botulinum toxin begin to appear within 3 to 5 days after the injection, but the full effects are visible after 7 days. A follow-up appointment for a free touch-up is scheduled one to three weeks after the initial injection to optimize the result and correct any possible asymmetries.

How long do the effects of botulinum toxin last ?

The effects of botulinum toxin generally last between 3 and 6 months, depending on the treated area, individual metabolism, and the dose used. With regular treatments, results may sometimes last longer, as the muscles gradually weaken over time. To maintain the results, it is recommended to schedule maintenance injections every 5 to 6 months, depending on your needs and aesthetic goals.

What should you do in case of side effects after a botulinum toxin injection ?

Although rare, some side effects may occur after a botulinum toxin injection, such as headaches, swelling, bruising, or slight facial asymmetry. Most of these effects are temporary and disappear on their own within a few days.
Here is what you can do if you experience side effects.

Take Arnica for bruising. However, bruises are usually very small and rare.
Take pain relievers such as paracetamol to ease headaches, but avoid anti-inflammatory drugs like ibuprofen or aspirin unless otherwise advised by your doctor.
Consult your doctor if you have concerns or if the side effects persist beyond a few days.

Swelling usually resolves spontaneously within 10 minutes. Any asymmetries are corrected during the touch-up appointment.
It is crucial to choose an experienced doctor to minimize the risk of complications and achieve optimal results.
