No interaction that I find of Voluma and Rosacea. If you have more specific questions, Allergan's consumer phone number is easily found and one can ask the company directly. Best Wishes!!
Voluma is a thick form of hyaluronic acid (HA) designed for adding volume to the face. The plane of injection is deeper than the average HA filler. There should be no exacerbation of your condition with Voluma or any other filler.
