Is This The Tyndall Effect or a Healing Bruise Under Eyes? (photo)

From the photos you have submitted, it does just look like bruising that is resolving and not the Tyndall effect. The Tyndall effect is more of a blue tinge right underneath the skin.

The first picture looks like a bruise (was this taken earlier?).  After 5 weeks one would not expect to still see a bruise.  Judging from the second and third photos I vote for Tyndall effect (which is actually a bluish color under the skin due to light reflecting over the filler).  Hyaluronic acid fillers like Juvederm are famous for this, especially under the eyes.  It can occur with deep placement because the skin is so thin under the eyes.  Check with your doctor and ask about hyaluronidase.  With one injection and 24 to 48 hours the material can be dissolved.  Unfortunately your correction will also dissolve to some extent.  In any event the color will go away on its own when the material naturally breaks down although that could take a year.

If the product was injected deeper, than bruising is typical, especially inder the eye area. Avoid Vitamin E, fish oil and products containing Ibuprofen for 2 weeks prior to injectable treatments. Also, if the injector uses ice under the eye immediately after the treatment, it does help to avoid these bruises.

From what I can see this looks more like a resolving bruise. Tyndall would be a gray/blue or purplish color. this looks more brown to me in the photo. Give it  some time. 

Thanks for the pictures.  That looks like hemosiderin deposition which is a result of the bruising and not the Tyndall effect.   It can take some time to go away, but it will. Some doctors believe Vit K creams can spped up the resolution.  We have also had luck with the pulsed dye (Vbeam) laser. Best to you.
