Refresh Optive UD

Suitable dryness severity: Moderate

Target tear layer: Aqueous + epithelial cell protection

Preservative and its effect: Preservative-free

Ingredients:

• Carboxymethylcellulose Sodium 0.5%: viscosity and stable hydration of the tear film (target layer: aqueous)

• Glycerin 0.9-1%: long-lasting humectant that does not blur vision (target layer: aqueous)

• Erythritol: osmoprotection of cells against oxidative desiccation (target layer: aqueous + epithelial protection)

• L-Carnitine (Levocarnitine): restores osmotic balance and normalizes cell function (target layer: aqueous + epithelial protection)

Additional benefits (beyond lubrication) / notes: Erythritol and levocarnitine (osmoprotectants) work independently of lubrication to restore the osmotic balance of epithelial cells and normalize their function
