Suitable dryness severity: Moderate – severe
Target tear layer: All three layers together (nano-droplet technology)
Preservative and its effect: PF version: preservative-free.
Ingredients:
Propylene Glycol 0.6%: main humectant for the aqueous layer (target layer: aqueous)
Mineral Oil / Dimyristoyl Phosphatidylglycerol: rebuilds the lipid layer and reduces evaporation (target layer: lipid)
Hydroxypropyl Guar (HP-Guar): forms a local gel in dry areas (target layer: aqueous + mucin adhesion)
Polyoxyl 40 Stearate / Sorbitan Tristearate: emulsifiers that combine the oil and water phases into nano-droplets (target layer: lipid + aqueous)
Additional benefits (beyond lubrication) / notes: A nano-droplet emulsion that combines a lipid phase (mineral oil and phospholipid) and an aqueous phase in tiny droplets that spread over the entire ocular surface, covering all three types of dry eye (aqueous-deficient, evaporative, and mixed)
