How long after botox can the botox migrate? Is 27 units enough to migrate? Where would botox migrate from the forehead?

There is a chance Botox can migrate in the first day or two after the procedure. The more Botox that is injected, the greater the risk for migration. However, experienced physicians with extensive training in Botox know how to mitigate the risk so it is extremely low. As long as you are working with a board-certified dermatologist with expertise in neuromodulators, you should not have any problems with your procedure.

Hello, thank you for your question. Yes, it can, but if it is injected properly these risks are minimal. To minimize risks further I recommend my patients avoid strenuous exercises and applying pressure to the region for at least 1-2 days following the procedure.

Botox has a short window where it can migrate.  Experienced injectors are aware of how the product works and where and where not to inject.  The larger the injection dose, the greater chance of migration.  If the product migrates it does so right around the injection site.  Speak with an experienced injector to learn more.

When injected, Botox will migrate slightly from the injection point.  In a clinical study, researchers found that Botox migrates 1.8 square centimetres from the injection point give or take 0.65 square centimetres.  Injectors are aware of this an take it into account when injecting.  Experienced injectors know which areas of the face to avoid to prevent any unwanted effects of Botox.
If you are considering getting Botox, I would recommend meeting with some experienced injectors in your area for a consultation so that you can discuss any concerns you may have prior to treating.  I have found that it is not uncommon for first time patients to have some questions and concerns prior to their first treatment, and then are very pleased with their results.

Hello and thanks for your question. Migration of botox happens quite quickly if you rub the area for example. We would warn patients to leave the area alone for 24hours to be safe of any migration as it's unlikely after this point. Always go to a qualified and experienced practitioner for any injectable treatment, best wishes

Botox and the other neurotoxins can migrate as long as they have not bound to the nerve, I.e. the time it takes it to work in you. The larger the amount injected in any one place, the further it is likely to migrate. That is why the microdroplet method , where small amounts are injected in multiple areas of the muscle. The most dangerous place for migration is just medial to and above the center of the eyebrow. This is because there is a hole in the fascia that separates the eye from the brow where a vessel and nerve traverses front the eye to the brow. Botox can potentially pass through this from the forehead to the muscle that holds the eyelid up. Therefore, not rubbing toward the eye after Botox until the Botox is working in the forehead is about the only restriction you should have after receiving Botox.
