Core Functions

Long-lasting Moisturizing & Lubricating

Hyaluronic acid molecules bind a large amount of water through hydrogen bonds, forming a thin moisturizing film that provides long-lasting hydration to the ocular surface and mucous membranes. This relieves dryness and foreign body sensation, replacing natural tears to meet daily needs.

Repairing Ocular Surface Damage

It promotes the connection and extension of corneal epithelial cells, accelerating the healing of corneal and conjunctival epithelial damage caused by cataract surgery, refractive surgery, eye trauma, or drug-induced damage, helping ocular surface recovery.

Enhancing Formulation Stability

Hyaluronic acid enhances the viscoelasticity of eye drops, prolonging the residence time of active drug components on the ocular surface. This reduces rapid loss, improves the duration of efficacy, and optimizes overall ophthalmic formulations.

Applicable Scenarios

Dry Eye Relief: Designed for products addressing endogenous dry eye conditions like Dry Eye Syndrome and Sjögren's Syndrome, targeted to relieve dryness from internal factors.
Post-Surgery Care: Ideal for post-cataract and refractive surgery eye drops to provide gentle care for ocular surface repair and mitigate post-operative discomfort.
Contact Lens Comfort: Applicable in contact lens lubricating and care solutions to ease dryness and foreign body sensations from prolonged lens wear.
Daily Fatigue Protection: Suitable for special eye lubricating products designed for individuals in air-conditioned environments or those facing high-frequency electronic screen exposure.
