Summary

Although injections of botulinum toxin are deemed to be risk-free and almost without any side effects if any, that still does not mean that no precautions should be taken.

What should you do before the injections?

Before the injections, it is generally recommended to avoid taking aspirin and anti-inflammatories to prevent the occurrence of haematomas.

The dermatologist or aesthetic doctor may advise the local application of an anaesthetic cream to limit the discomfort for very sensitive people.  However, in general injections of botulinum toxins are carried out using very fine needles, during sessions which only last a few minutes and which are relatively painless.

What should you do after the injections?

Once the injections have been carried out, it is usually recommended not to massage, rub or touch the treated area. Instead, it is recommended that you strongly contract the treated muscles for several seconds, three times a day for three days.  Intensive physical activities are banned and lying down in the hours following treatment must be avoided.

It is also essential to stay alert and minimise the risks of knocks and bleeding on and around the treated area to avoid losing the product. Botulinum toxin, capable of blocking the communication between the nerves and the muscles, must not leave the area into which it has been injected.

Most of the time, the treated area will swell up.  That does not generally last more than 20 or 30 minutes.  Redness, bruises or oedemas can also occur, before normally disappearing rapidly.

Remember to follow the advice of your dermatologist or aesthetic doctor when following these pre- and post-injection steps.
