Description

Thealoz Duo combines trehalose and sodium hyaluronate to deliver intensive moisture and cellular protection. Trehalose helps protect the surface cells of the eye from dryness and environmental stress, while sodium hyaluronate provides lubrication and long-lasting hydration. This dual-action formula helps stabilise the tear film and reduce symptoms such as burning, stinging, and the sensation of grit in the eye. The preservative-free solution is gentle enough for frequent use. It is particularly beneficial for people experiencing dry eye due to screen use, air conditioning, or environmental exposure. Regular use helps maintain comfort and support the natural recovery of the ocular surface.

 

Directions

Wash your hands thoroughly before applying the drops. Instil one drop into each affected eye as needed throughout the day, or as advised by a healthcare professional. Blink several times to ensure even distribution across the eye surface. The drops can be used while wearing contact lenses. Avoid touching the dropper tip to the eye or any surface to maintain sterility. Close the bottle securely after use. Follow the instructions on the packaging regarding usage period after opening.
