Risks of Repeated Injections and Damage to the Skin with Dermal Fillers?

It depends how long the discoloration and broken capillaries have been present for.  If they have been present for greater than 1 month after injection, you will most likely need lasers to address the capillaries. The discoloration may be secondary to product, so it is difficult to say without a photograph on what will help that.

Broken capillaries happen with age and are unlikely related to the dermal fillers.  Discoloration can happen from bruising but it usually gets bettter wtih time.

At the most recent Multispecialty Cosmetic Symposium in Las Vegas, several Plastic Surgeons noted that the skin was much more youthful appearing when they were doing facelifts in patients who did filler.  I think that doing filler with needles around the tear troughs is not the state of the art and only cannulas should be used there.  This will decrease the bruising and swelling after the procedure.  I have written a blog recently discussing that HA fillers might actually help with cancer prevention and increase your longevity.  Please read it.  Steve Weiner, MD

If the discoloration is from hemosiderin staining it will go away with time. Broken capillaries can happen from injections, but they can also just happen with aging in general. So it's hard to say if the broken capillaries are all from the injections. However, I would say that using a cannula under the eye means less injections to that sensitive area, so if you are sure the discoloration and broken capillaries are from repeated injections, cannulas may be a great answer for you.
