Wider dark circles under eyes after Restylane. Any suggestions?

A week after Restylane injections you might still be bruised, I would give it another week for Restylane to settle in.  Generally, you have to be very careful when injecting around the eye area because if fillers are not injected properly in this area, they can actually increase dark circles or even create them.  In your case, we don't know if it's bruising, hyperpigmenation or Tyndall effect.  This effect happens from scattering of light through thin eyelid that occurs when an HA filler is placed superficially in the skin.  Luckily Restylane can be dissolved away with a hyaluronidaze if there is a problem.  Hyperpigmentation could be addressed with Intense Pulse Light laser treatment or/and hydroquinone pads.  See your injector for a follow up to address the issue.

You may have the Tyndall effect which is a bluish discoloration from the hyaluronic acid, but it could be just bringing out the pigment that was there already by pushing up and smoothing the skin. use vitamin K or a combination of A and K which you can get from International Cosmeceuticals in Miami
