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

It can take up to 2 weeks for this to go away, and your photo shows that it's on its way out, since it's no longer all purple and red - there's yellow. However, I should ask if it was actually Botox that you received, or filler? 

In our office, we utilize the Plato's Bruise Balm for patients who develop bruising after injections or fillers. The Bruise Balm may help expedite the resolution of your bruise. Best, Dr. Karamanoukian Los Angeles

Pulsed-dye lasers and focused IPL treatments work well to expedite the resolution of bruising.  The laser energy targets breaks up the pigment and allows your own body to reabsorb them more quickly.  It's important to seek out a physician experienced and familiar with this indication to achieve the best results.
