Description

Becodefence has thixotropic properties, which when shaken turns the original gel-like consistency into a fine fluid that can be sprayed easily up in the nose and reaches a broad inner surface of the nasal cavity, where it immediately resettles as a stable, impermeable barrier. Research shows that even very crude application methods such as ointments or creams, which achieve less coverage of the nasal mucosa cause significant improvement of symptoms.

The conjunctiva will not be exposed to allergens directly, so the symptoms that origin from the conjunctiva’s mast cells will be less severe than the ones caused in the nasal mucosa. The mast cells are also present in the conjunctiva underneath the eyelids. Although the conjunctiva is not exposed directly to allergens in the air, allergens touching the exposed cornea may be trapped by tears and could be distributed to the conjunctiva.

This indicates that only the areas that are reached by Becodefence fine spray need to be covered, as the inhaled pollen will basically reach out to the same areas.
