Hylo-Night nighttime ointment

Overall target layer: Lipid

Preservative and its effect: Preservative-free

Ingredients:

• White Soft Paraffin (Petrolatum): occlusive lipid barrier that fully prevents overnight evaporation (target layer: lipid)

• Liquid Paraffin (Mineral Oil): softens the ointment and helps it spread evenly (target layer: lipid)

Additional benefits (beyond lubrication): Forms a complete barrier that prevents evaporation all night; especially useful for incomplete eyelid closure (lagophthalmos) or severe nighttime dryness. Technically it is a paraffin ointment rather than a carbomer gel, but it is marketed in the thick nighttime lubrication category alongside gels
