Migration of Botox

There is a standard amount of diffusion or spread of the Botox that occurs after injection. You should not bend down for several hours after Botox to minimize this diffusion. Botox is not usually injected immediately above the mid eyebrow to avoid diffusion into the upper part of the eyelid muscle. The inner eyebrow can be injected right above its location. Some patients need more units of Botox than others and depending on the volume of dilution that is done during the preparation of the Botox in the doctor’s office, some doctors need to inject more volume of liquid than others to administer the same number of units. If the larger dilution Botox is injected close to the middle of the upper eyebrow then some diffusion can result in a droopy upper eyelid. Fortunately, this is temporary, but can last a few months. There is an eye drop that your doctor can prescribe to help the upper eyelid lift up a little and make it more pleasant for you during the waiting period for it to wear off.
