Botox Bruise - How long will it be like this? Will ultrasound or laser help at least to change a color to yellow?

Hi Vow.  That is an extremely pronounced bruise for Botox injections.  In addition, Botox is usually not injected under the eye.  Was this at the outer eye for crow's feet or could it be a dermal filler for under eye circles?  The latter is much more likely to cause the kind of bruising you have.

In any event, this kind of bruising is resolved pretty easily if it is treated at approximately 48 hours after the injections with a pulsed dye laser (V-Beam and V-Star are most common).  These types of lasers are highly absorbed by hemoglobin and so are able to heat and break down the blood causing the bruise.  The key is not to wait too long.  After the bruise starts to turn yellowish, the procedure will not work.  Our experience is that this is anything past 72 hours after injection.  Good luck.

Eating Pineapple for the Bromelain is a good start.  The millions of people who believe in homeopathy can't all be wrong.  Arinica Montana, in both under-the-tongue tablets and gel form will help it too.  Keep Arnica around the house for that unanticipated bump or trauma.    Take Arnica on your way to your next Botox treatment.

Bruising after Botox can occur. Most of the time it is visible the same day or the very next day. In some cases, however, it may become visible several days later. A bruise occurs when blood leaks out of a traumatized blood vessel. It could be that with strenuous activity or rubbing or due to blood thinners that an injured blood vessel dislodges a clot and causes some blood to leak into the tissue and thus cause a visible bruise (e.g. heavy exercise a few days later may results in a bruise). The bruise typically dissipates within a week or two.  We often use Intense Pulse Light (IPL) to accelerate the clearance of a bruise.
