Part 1: In the first installment of our hyaluronic acid review, Dr. Dzubur delves into the latest addition to the U.S. market, iVizia. This product, initially marketed as Thalazo Duo in Canada, made its U.S. debut just last year, offering a smoother and less viscous hyaluronic acid-enhanced lubricating drop.
In the world of eye care and lubrication, understanding the science behind hyaluronic acid (HA) and its unique properties is essential. Hyaluronic acid is often likened to a spaghetti-like molecule, and this analogy holds true when discussing its remarkable "stay power" on the ocular surface, especially when compared to lubricating drops that rely on glycerin as the primary lubricating agent.
Hyaluronic acid is a naturally occurring polysaccharide found in various tissues throughout the human body, including the eyes. It has a unique molecular structure characterized by long chains of repeating sugar units, which indeed resemble strands of spaghetti. This molecular structure allows hyaluronic acid to excel in providing long-lasting hydration and lubrication to the eyes.
When applied as a lubricating drop, hyaluronic acid molecules create a thin, viscoelastic film over the ocular surface. This film adheres to the cornea and conjunctiva, effectively trapping moisture and preventing it from evaporating. The spaghetti-like chains of hyaluronic acid entwine with each other, forming a cohesive network that maintains its integrity and hydration properties over an extended period.
