Should that be determined by your derm? Those 2 fillers are for different purposes. AFAIK , volite is for superficial scar, but volift is for relatively deep scar

I'd be very careful with fillers. They look fine at first but can lead to lumpiness down the road. Irecommend reading Mr. Matt's thread in total. He never had any filler but instead used suction after his subcisions:
