Is This Tyndall Effect? (photo)

Looks to me like you have nothing more than a bruise, which will also cause a little swelling.  A Tyndall effect happens when the filler is too close to the surface causing the blue wavelength spectrum of light to cause a light blue hue, like the color of blue eyes.  Looks like you are purple, ie. bruise.  Give it a couple of weeks to resolve and it might get a little worse before it gets better.  Make sure that you wear sunscreen all the time as the inflammation from the bruise may cause some hyperpigmentation which may take longer to go away than the bruise itself.  Arnica and Vit K probably will not help, but they won't hurt. 

Midlife Mom....Take a deep breath...You will be ok.  It is too early just yet to tell if this Juvederm injection will cause the Tyndall effect.  Right now from your photograph it appears as if the discoloration may simply be " black and blue."  Give it at least tow weeks for the swelling to resolve.  In the worst case scenario the doctor can make the filler dissolve with hyaluronidase. Sit tight breathe easy.

Looking at your photos, it appears you just have some bruising. This should resolve over the next 1-2 weeks. I would recommend communicating any concerns to your surgeon, as they know the extent of your treatment. I hope this helps, and I wish you the best of luck.
