Regarding seasonal mucosal injury, clinical care focuses on "hydration" and "barrier repair." Traditional care often suggests the use of petrolatum (Vaseline); however, oil-based products may inhibit ciliary motility. Current care trends favor the use of water-soluble or highly biocompatible materials. For instance, sprays containing hyaluronic acid form a sustained moisture layer on the mucosal surface. This assists in maintaining the physiological hydration of epithelial cells and prevents dryness-induced cracking and crusting, making it suitable for daily maintenance and environmental protection.

However, if the nasal mucosa already exhibits micro-trauma or frequent bleeding, simple moisturization may not offer sufficient protection. According to the 《American Family Physician》, film-forming liquid bandages, such as Hi-Mupro Nose Liquid Bandage Spray, play a critical role. Unlike simple moisturizers, these products are designed to form a physical thin film. This film effectively covers damaged capillaries and mucosal tissues, isolating them from the irritation of dry air and mechanical friction, thereby providing a stable microenvironment for repair. By combining active hydration with the barrier protection of Hi-Mupro, a comprehensive defense strategy for the winter nasal mucosa can be established, effectively reducing the incidence of seasonal epistaxis at the source.
