I received Botox on my forehead 3 days ago, the dr hit a major vein? (photo)

Bruising can occur when having getting a Botox, give it a few weeks to resolve and continue seeing your provider for follow up

Dear andimiss, Bruising is the most common side effect from Botox injections. Once the bruising resolves, you should be fine. I doubt the vertical line will be present when the swelling abates. #Dr. Gervais

It is always possible to develop a bruise after an injection of Botox, but it will resolve.  The vein will return to its normal state soon, without any creasing.  If you are still concerned, please see your doctor.

Please allow at least 1 month healing time before 'freaking out"! Also week;y visits to the injecting doc allows a close follow up.. 

You are going to be fine once the bruising resolves. Because the veins beneath the skin cannot be seen, occasionally they are hit by a needle. That needle may be for Botox or a filler or even an injection for anesthesia. No permanent damage to the vein will occur.
