Hello. Thank you for visiting our store, we buy things in a licensed pharmacy in the European Union. Systane COMPLETE is an all-in-one moisturizing eye drop from Alcon. These eye drops provide long-lasting relief, hydration and comfort to your eyes by stabilizing all 3 layers (mucin, water and lipids) of the tear film. Say goodbye to the discomfort caused by dry eye syndrome. The drops provide protection against tear evaporation, thus preventing the surface of the eye from drying out. The drops contain nanoparticles that fill all areas where the tear film is missing with great precision. They will also protect the entire surface of the eye from harmful environmental influences that can irritate your eyes. Ingredients Propylene glycol, hydroxypropyl guar, mineral oil, dimyristoylphosphatidylglycerin, polyoxyl 40 stearate, sorbitan tristearate, boric acid, sorbitol, disodium edetate, preservative POLYQUAD (polydronium chloride) 0.001%, distilled water. Dosage Always shake the bottle well before using the drops. Then put 1-2 drops in each eye and blink so that the liquid can evenly cover the eye. Do not use these drops if you wear contact lenses. The drops can be used before using contact lenses or after contact lenses are removed from the eyes.
