Sound waves to smooth wrinkles? new study tests ultrasound for sagging skin

This study tested whether focused ultrasound can safely improve mild to moderate facial skin looseness (laxity) in adults. Nineteen participants received a single treatment session on both sides of their face, with different hand-pieces used on each side for comparison. Researchers measured skin changes using a special imaging system and tracked any side effects over six months. The goal was to see if this non-invasive procedure offers a meaningful cosmetic improvement.
