There's blue on my lips and tingling a month after Restylane. Is this worrisome? Will it get worse? (photo)

Restylane classic if is injected too superficially, can cause tyndall effect. ANd it appears that this is what you have. I prefer Juvederm or Restylane refyne for the lips. they do much better with less possibility to cause tyndall issues.  

This is an infrequent side-effect with Restylane injections, specifically with Restylane Kysse. The filler tends to collect into these discrete “gell balls”. In my practice, I would first attempt vigorous massage of the lips and if that doesn’t resolve the issue, I would dissolve completely and inject with Juvederm or any other filler.

Based on the photograph, it seems the filler may have been placed too superficially, which can lead to the bluish discoloration and also the irregular contour of the lip. I would recommend seeing your injector back for further evaluation and consideration of dissolving the filler.
