Duestom 18 % Gel is used for maintaining moisture in the mucous membranes of the oral cavity. Glycerol attracts and binds water molecules from the surroundings and underlying tissues, helping alleviate dryness and supporting a moist surface environment. It supports sustained hydration over time. The gel forms a viscoelastic barrier over the mucosal or skin surface, reducing irritation from friction, dryness or external stressors. This barrier helps to trap moisture and shield vulnerable tissue from further damage. By creating a soothing film and restoring hydration, glycerol helps relieve mild discomfort, burning or scratchiness in dry tissues. It can calm inflamed or irritated areas by improving the local environment.
