“Blue shadowing and pain post restylane”

I have loved the Restylane and Botox treatments for a long time... until this issue. I think this is unusual and I'd like to have an alternative moving forward, if there is one that won't result in this discoloration.

I have had Botox injections around my lips for many years and Restylane injections in my lips for a few years. My last set of injections was four months ago. Sometime thereafter, I noticed what appeared to be a blue shadow or line around my lips.

It looks like bruising but it doesn't go away (and it doesn't look like it's going to anytime soon). It also looks to be very oriented to the surface of my skin. I also have a mild burning sensation in my lips that is constant It feels like it does after the Anesthetic wears off after the injections... the mild pain of being poked too much with needles that fades soon after.... but it isn't going away this time.
