Can a Needle-and-Heat combo rejuvenate your face?

This study looks at whether a procedure called microneedling radiofrequency (which uses tiny needles and heat) can improve skin and fat thickness in the face, and if adding a topical cream (poly-L-lactic acid) makes it work better. About 30 adults seeking facial rejuvenation will take part. The goal is to see if the treatment improves appearance and how satisfied patients are.
