Artelac Nighttime Gel is an eye gel with a combination of agents designed for people with dry eyes (chronic tear dysfunction). Artelac Nighttime gel is a highly viscous formulation providing three layers of film stability for overnight comfort, all of which provide lasting hydration to combat dry eyes. It contains Trigylceride lipids to seal in moisture, Carbomer gel to prolong adhesion to the surface of the eye, and sterile water which compensates for water loss.
