Ivizia products are a new brand name in the US as of 2022. They are made by Thea Pharmaceuticals. They're being advertised quite widely and are available in drugstores, so chances are you've come across them (at least the drops) by now.
This gel is too thick for a multi-dose bottle, so it's in single-use vials. But don't forget to check out Ivizia Lubricant Eye Drops - they're in a particularly good multi-dose bottle and come in two sizes.Ivizia is a slightly modified version of Thealoz Duo, a very popular European product.
There are several things to like about the Ivizia line of drops/gel:
1. Preservative-free eye drop brand
Ivizia brand eye drops are preservative-free. I really appreciate this feature. When a brand is PF, you don't have to stop and think, you don't have to hunt and label-read quite as carefully. Most major US brands, by contrast, have both preserved and unpreserved versions of the very same product. That might be fine for people who are "preservative-savvy" - they know how to tell them apart easily. But it puts many people at risk of preservative exposure without knowing anything about the issue.
2. Ingredients
POVIDONE: The reason povidone is in this product is because the FDA will not let companies list sodium hyaluronate as an active ingredient, so European companies who are bringing their HA drops to the US are having to reformulate them and add something else. Most HA drops in the US currently have glycerin, with the exception of Systane Hydration, which has the usual Systane suspects (polyethylene glycol and propylene glycol). So using povidone as the active is a new thing in the HA drop world. Povidone tends to be thought of as rather 'old school' for a lubricant drop. Personally, though, I've always been a fan.
SODIUM HYALURONATE: As you know if you've read anything I've written about eye drops, I'm a big sodium hyaluronate (HA) fan. However, not all HA is equal. The higher the molecular weight, the better - and the more expensive. While Ivizia gel is about as thick as other "liquigel" type products that are in single-use vials, we don't think it has the higher molecular weight HA, so it remains to be seen how it will compare (for overnight use) to the known higher molecular weight ones (Oasis Tears Plus and Optase Dry Eye Intense, in particular). Make sure to post your experience in the reviews or shoot us an email!
CARBOMER: Increased viscosity.
TREHALOSE: I don't have the technical knowledge to explain why this is 'good stuff', but there's definitely a reason why it's been creeping into more and more US drops. This is a key feature of Thealoz Duo (3%, in fact, though I don't know how much of it is in Ivizia).
