Botox Around Eyes and Dilation of Blood Vessels?

Botox relaxes the muscles. The veins are usually below the muscles. As the muscle does not have any tone, the veins can get engorged and become visible. Unfortuantely it is an unwanted side effect of Botox that is hard to avoid.

You might have to choose between wrinkles or veins.

Botox doesn't cause dilation of blood vessels and doesn't typically last six months. You might want to consider other reasons this may have occurred and visit with your primary care physician.

The most common side effect of Botox around the eyes is some temporary bruising.  The effect you are describing is not commonly seen.  However, Botox is now being used to help improve blood flow such as to the fingers in patients with poor circulation.  It is thought that Botox acts on the smooth muscle of vessels to cause dilation.  Now, usually there is not much smooth muscle in veins, but this may be the cause of your vein dilation that you have seen.  It is difficult to know if this will be temporary since it is not a well-known event.
