You may still have some residual filler in the eye area. What you may be describing is the Tyndall Effect This can occur with ANY form of hyaluronic acid filler. It occurs when injection is superficial. If you had the same injector and the only difference was a change from Restylane to Juvederm, perhaps Restylane is better for you. If you had a different injector, perhaps s/he injected differently than the prior injector(s). It could even be a case where the filler type makes no difference, but perhaps this time the injection was just a bit more superficial. Injection of hyaluronidase can help dissolve any residual Juvederm. Best of luck.
Thank you for your question. Even 1 year later, it's possible that you still have some slight residual filler that was placed too superficially causing a Tyndall effect - a bluish discoloration to the skin. This can easily be reversed with a hyaluronidase, like Vitrase. I prefer restylane or restylane silk placed deeply in the tear trough region - in my hands at least, there is less of a chance of Tyndall. Best of luck!
The photos are limited but what you seem to be describing is the Tyndall effect which is caused by superficial placement of the filler. The treatment for this is reversal of the filler. You can then have the filler placed deeper (preferably below the orbicularis muscle in the case of the tear trough). See an expert injector for the reversal and re-injection. I actually prefer Belotero for injection into the tear trough. Less change of Tyndall effect with Belotero.
