I am scared to death 1 vial Radiesse per cheek will be conspicuous. I am 70 yr old guy, getting upper bleph

If you are really worried about getting too much filler, it might be wise to start with a hyaluronic acid based filler, ie Juvederm or Restylane.  These fillers are reversible with an enzyme injection, as opposed to Radiesse, which is not.  1 vial of filler per side for cheeks is not a crazy amount.  Sometimes we will inject 2-3 times that much in certain cases.  Just have an open, honest conversation with your surgeon.  

Thank you for your question. I don't think you have to worry too much about single vile being over done in your cheeks. For better or for worse at 70 typically it takes a lot more product to see an excess a result. Just express your concerns to your surgeon and I'm sure they will do what you're looking for. Good luck 

Radiesse comes in two volume vials.  There is a larger 1.5cc vial and a smaller 0.8cc vial.   1.5cc per cheek is likely only going to produce a subtle difference in each cheek in a 70 year old without prior injections.  Having said that, you can always elect to wait for the filler injections and have them done while you are awake and can see the results of injections while it is being performed.  I suspect you will want the larger volume in each cheek.  Good luck!
