Darkened Skin After Restylane?

   These darkened areas, if the result of bruising or heme pigments staining the skin, typically improve with time. 

Without viewing photographs of the areas you are referring to, it is very difficult to answer your question. You should consider posting pictures for better assessment and immediately follow up with your provider if you have complications post-treatment.

Hi Anda.  If you are olive or black skin, it's possible that the trauma left some darkening or hyperpigmentation.  This is usually remedied with hydroquinone, but it's best to ask your injector what he/she thinks about treatment.  There is a more serious condition called hemosidering staining which is often associated with severe bruising in darker skinned patients.  This is a possibility as well and we use q-switched lasers to treat that issue.  Good luck.

It is difficult to say without pictures, but it sounds as if you have what's called hemosiderin staining from the bruising following the injection.  This can be more prominent in some patients depending on factors such as your skin type.  The good news is for most this will fade away with time. 
I would recommend having a follow up with the physician who did your injections.  Best of luck!

Your dark spots from Restylane injections are most likely secondary to heme or bruising from local injections.  If it persists you may seek out a physician who performs V-Beam and can laser the residual bruising.
