Thealoz Duo

Suitable dryness severity: Moderate – severe

Target tear layer: Aqueous + epithelial cell protection

Preservative and its effect: Preservative-free (ABAK system with a 0.2-micron filter that mechanically prevents contamination).

Ingredients:

• Trehalose 3%: cell protection and activation of cell survival mechanisms in severe dryness (target layer: aqueous + epithelial protection)

• Sodium Hyaluronate 0.15%: hydration and viscosity that prolong retention of the solution on the surface (target layer: aqueous)

Additional benefits (beyond lubrication) / notes: Trehalose stimulates cellular autophagy, which helps epithelial cells survive under severe dryness – a biological effect independent of lubrication
