Randomized Controlled Trial Multicenter Study Comparative Study
Comparison of injection comfort of a new category of cohesive hyaluronic acid filler with preincorporated lidocaine and a hyaluronic acid filler alone.
A smooth, cohesive, 24-mg/mL hyaluronic acid (HA) gel with uniform consistency, even flow characteristics, and extended duration was designed for injection into the mid to deep dermis. ⋯ The smooth, cohesive HA gel with preincorporated lidocaine increased subject comfort during treatment and improved the injection experience.
