Facial tightening using a novel vacuum-assisted microneedle fractional radiofrequency system: A prospective, randomized, split-face study.

The vacuum-assisted MFRS is safe and effective and is recommended for improving facial tightening and reducing wrinkles. This technology is sufficient to ensure the insertion depth, thus helping to improve the treatment accuracy and safety. The MFRS provides sustained effects for at least 6 months.
