Mechanism of action

Hydroxypropyl-guar is a natural polysaccharide derivative that increases tear film viscosity and provides prolonged ocular surface lubrication. It adheres to the corneal and conjunctival epithelium, reducing friction and protecting against further irritation. This mechanism is particularly effective for dry eye disease by maintaining moisture and reducing evaporation.
