SIFI EYESTIL SYNFO, thanks to its components, protects, moisturizes and lubricates the ocular surface. It is indicated in all cases of ocular discomfort and dry eyes caused, for example, by: Dry eye syndromeEye surgeryAllergic reactionsChronic use of topical medications (such as ocular hypotonizing agents, preservative-containing eye drops, etc.)Use of systemic medications (such as hormone replacement therapy, antihypertensives, antidepressants, antihistamines, etc.)MenopauseAgingStress related to environmental factors (pollution, air conditioning, smoke, wind, etc.)Prolonged use of electronic devices (computer, tablet, phone)Use of contact lenses. The product does not contain preservatives, so it can also be used by contact lens wearers. SIFI EYESTIL SYNFO contains two natural polymers, sodium hyaluronate and xanthan gum, with lubricating, moisturizing and mucomimetic properties. The reepithelializing and antioxidant effects of both components are augmented by their synergistic action. SIFI EYESTIL SYNFO also contains glycine and betaine, substances with osmoprotective action that favor the maintenance of cellular homeostasis which is usually altered in cases of dry eye. Glycine and betaine play a role in the remodeling phase of the ocular epithelium during the healing processes, acting as osmoprotectants on cells exposed to hyperosmotic stress. Thanks to the combination of sodium hyaluronate, xanthan gum and osmoprotectors, SIFI EYESTIL SYNFO hydrates, lubricates and repairs the ocular surface, helping to restore homeostasis and protecting it against oxidative damage. SIFI EYESTIL SYNFO also guarantees a long-lasting sensation of soothing and maximum comfort.
