The softer hyaluronic acid (HA) fillers, such as Juvederm XC Voluma, are among the easiest of fillers for providers to inject. These fillers are more likely to attract water and make your face appear puffy. On the other hand, firmer fillers such as Radiesse and Sculptra are often the best for the cheeks. Firmer fillers are more technically difficult to inject but are much less likely to attract water and cause a puffy appearance. There is no one- size fits all cheek filler. An experienced injector will have expertise with all types of fillers. The most important variable by far is the skill, expertise and the aesthetic eyes of the injector.
