Vycross technology is the term that Allergan uses to describe the unique cross linking of high and low weight HA in their Voluma and Volbella fillers. It is what allows these fillers to restore volume in a natural looking way. Hope this helps.Kindly,Kouros Azar
Vycross Technology is an excellent way that Juvederm has evolved which makes it more "spongy" and gives you an immediate lift. Please consult an expert for the best cosmetic results. Best, Dr. Green
