New filler study shows smoother smile lines with minimal risk

This study tested Decoria intense, a hyaluronic acid filler already on the market, to confirm it safely reduces nasolabial folds (smile lines). About 80 adults with at least moderate wrinkles received the filler, with an optional touch-up. Researchers measured wrinkle severity and tracked side effects over 12 months. The goal was to meet new EU safety rules and confirm the filler works as intended.
