no problem. a cc and a ml are exactly the same thing. the percentage of product may be sometimes misleading. for example, juvederm reportedly has a higher concentration of product but ultimately the result between the two products (restylane and juvederm) are about the same. if anything, juvederm tends to spread out a bit more in the cheek or other areas so i don't prefer it as much given the fact that it moves a bit from where i put it so that is something to consider. for products like radiesse or artefill, then the gel carrier and collagen, respectively, should be factored in when considering total volume. in addition to that, these products will have about 20% variability based on how much collagen grows around the product. the more that your body responds with collagen growth, the more the long-term effect will be. radiesse claims that the tissue ingrowth and the gel carrier are exchanged on a 1:1 level. i have not found that to be the case. finally, some products are overfilled even though it is advertised as 1 cc. for example, radiesse is overfilled to 1.3 ish and restylane is overfilled to 1.2 ish.
