Voluma is different than botox. Both require the provider to understand the anatomy of the face, its blood flow distribution, bony landmarks and nerve pathways.As a deep filler Voluma is placed often on top of the bone underneath the muscles. The injector needs to be cautious not to inject into a blood vessel and have the filler travel through the vein or artery to vital structures. Some side effects of injecting fillers are: bruising, infection, soreness,lumpiness, temporary numbness and undercorrection. Complications include but are not limited to: immune reactions causing delayed granulomas, nodules or lumps, bleeding collecting underneath called a hematoma, interference with circulation and scabbing of overlying skin causing scarring, overcorrection, intravascular (within a blood vessel) spread, and even but fortunately extremely rarely, blindness.It is best to see a board certified dermatologist or plastic surgeon for Voluma, or any filler and / or Botox.
