Abstract: A nasal dilator that includes an upper resilient member for dilating the nasal valve and a lower resilient member for dilating the nostrils. The upper resilient member and lower resilient member may be attached to one another by a flexible substrate having a middle portion that is narrower in length than the upper or lower resilient members. The nasal dilator also may have adhesive tabs extending downwardly from the lower portion of the substrate on either side of the nose and towards the nostril entry, for temporary attachment to the side of the nasal vestibule to reduce nostril collapse. The nasal dilator also may include bendable or configurable hooks extending downwardly from the lower portion of the substrate and towards the nostril entrance for insertion into the nostril to reduce nostril collapse.
