3 months voluma injected 2 ml. i had vitrase 6-7 times, but the dosages used by doctors were low . 75 ml of voluma got btw 40 to 125 units, 4 days ago 125 units of vitrase, barely any visible effect) 40-50 units per area injected with 50 -55 ml of voluma. hardly working , dose must be too low. how many units can you safely inject without hurting my skin? does the approach of injecting little vitrase work eventually and soften/break down the filler? any voluma reversal experts in ny?
