HIKO is a procedure that combines hyaluronic acid filler with biocompatible dissolvable threads to enhance both the nose bridge and the tip. This differs from conventional nose filler, which primarily adds volume to the bridge using filler alone. HIKO can create a more defined shape from the bridge to the tip, and the threads help support the filler for improved contouring. As the threads dissolve, they stimulate collagen production, helping maintain natural-looking volume even after the filler is absorbed.
