I had 1ml of Voluma put in my cheeks last week. Is this the normal amount?

Hi, I'm annette. I'm 50 and get filler in my cheeks, too. Last time, my doctor invited me to try Voluma. It was more expensive ($750 for 1ml) than Radiesse ($500 for 1.5ml). They claimed that the Voluma "lasts longer" (very subjective), but I would have to pay for 3 syringes with Voluma to get the same look I get with Radiesse. I usually get 1.5 ml per cheek, so this would have cost me a lot more. I decided against it. Regarding the "normal amount", there is no normal amount. It takes what it takes to get the look you want. I would need at least that much and maybe more!!
