title: Delayed inflammatory reaction to hyaluronic acid (Restylane).
abstract: A 45-year-old man received an injection of Restylane (cross-linked hyaluronic acid) to a mid-forehead furrow line in an attempt to reduce its prominence. The injection was uncomplicated and successful in reducing the line. Five months after the injection, he returned with an inflammatory reaction in the area of injection that resolved without treatment over a period of 3 weeks.
