2 days post-Juvederm ultra plus: I've developed brown spots near the injection site; what can I do? (Photos)

How Can I remove the brown spots after filler injections (juvederm ultra plus)? I had some bruising (reddish) but these darker brown spots do not appear to be bruises. Will the brown spots go away and what are my treatment options to remove them quickly? I have a special outdoor occasion coming up and I will sweat off make up. Thanks.
