Description: The light source of the rhinitis treatment device emits a special red light that protects the mucous membranes of the nose against allergy factors. The red light slows down the response of immune cell receptors to irritants such as pollen, and this specific light wave leads to a reduction in the permeability of the mast cell wall, which means that the release of histamine is reduced, and the binding of the immune cells is locally affected, which in turn reduces the response to allergy factors
