iS Clinical makes the same claim for this eye gel as it does for their C-15 Serum Advance. First, I am skeptical about the claimed amount of vitamin C (in this case, 7.5%). That’s because the ingredient that precedes it on the list, sodium hyaluronate, typically is present in amounts of less than 1% in skin-care products. But, assuming iS Clinical is including 7.5% vitamin C in this serum, what does that mean for your skin? Topical vitamin C has multiple benefits for skin at various concentrations. You don’t need to seek out super-high concentrations. In fact, doing so can promote too much irritation, which is one of the downsides of applying ascorbic acid to skin. Irritation is never the goal because it causes collagen to break down.
When vitamin C is present at concentrations of 5% or greater, it may exhibit a significantly greater effect on improving wrinkles and skin discolorations. Its success depends greatly on how it is formulated and packaged, and therein is this serum’s problems: The form of vitamin C (ascorbic acid) is very unstable in the presence of air, and this packaging easily lets air into the bottle with each use. That means the vitamin C content of this serum will become useless within days (Sources: Cosmetic Dermatology, Second Edition, McGraw Hill Medical, 2009, pages 297–298; and Pharmaceutical Development and Technology, volume 11, 2006, pages 255–261).
The only concern is the inclusion of zinc sulfate. This ingredient is created from the reaction of sulfuric acid and zinc, and it is one of the forms of zinc that can be a skin irritant (Source: www.naturaldatabase.com). None of this is good news for your skin or your budget.
This eye treatment has a cutting edge formula that effectively combines 7.5% Vitamin C with Copper Tripeptide Growth Factors for enhanced anti-aging benefits.

From a marketing point of view iS Clinical is trying to be yet another "cosmeceutical" line of products designed by physicians and pharmacologists. The owners of iS Clinical claim to have assembled a "world renowned" team to bring consumers the best in anti-aging skin care and what they describe as "anti-aging medicine," even though iS Clinical products aren't about medicine any more than a spoonful of sugar is about medicine (with apologies to Mary Poppins).
The "iS" in the brand's name stands for "innovative skincare." Couple this with the "clinical" portion of the name and it's hardly surprising that lots of consumers concerned about aging skin are wondering yet again if this is the final frontier for their older looking skin. We'll cut to the chase: iS Clinical isn't the anti-aging line to beat, buy, or borrow. In many ways, several of their products are either dated, antiquated formulations or basic one-note products. Overall, their products don't hold up to lots of other products with far superior formulations, many of which cost a lot less, such as Clinique, Estee Lauder, and Paula's Choice to name a few.
The prices for iS Clinical products are definitely on the high side, which is one reason why it's critical that you know which ones are worth the splurge and which ones are a must to avoid, not only for the sake of your beauty budget but also for the health of your skin. As usual in such lines, there are a handful of outstanding products to consider, but there also are a lot to watch out for.
Back to the team behind this brand: If they're indeed preeminent men and women in their fields, it's truly embarrassing that they've created products whose claims are not based on proven, substantiated scientific research. For example, instead of using thoroughly researched exfoliants, such as glycolic acid or lactic acid, iS Clinical went back to the 1990s fad of including mixed fruit and sugarcane extracts for exfoliation. Think of it as using a typewriter instead of a computer; why would you ever go back to a typewriter?
Another shortcoming is their Active Serum for acne, which contains a lot of skin-damaging alcohol and menthol (both really bad for skin), while being void of ingredients proven to benefit blemish-prone skin.
One more point: iS Clinical promotes, under their "Integrity" header on their Web site, the idea that they "…strive to dispel myths in the skincare industry by disclosing and clinically validating all of the ingredients we use." However, there is absolutely not a shred of clinical validation anywhere to be found. It seems that iS Clinical wants you to think they're doing the consumer a favor by providing ingredient lists on each product, but disclosing ingredient information is required by law and has been in the United States since 1976—it's not a discretionary decision cosmetics companies can sidestep, although some have tried! Besides, the company's site only lists key ingredients (those they want to play up) so you're still not getting the full story.
It's almost funny, but not really, that as a way to explain the rationale behind their formulas, they have a section on their Web site called "Clinical Opinions." Well, "opinions" are not the same as scientifically validated research, and that's precisely what is lacking. In fact, the information presented has little to do with skin care. It's actually bizarre because the only thing they provide is a set of the same tired before-and-after pictures and improvement charts for certain products; but, without knowing key details about how the tests were performed and under what conditions the pictures were taken, they aren't just opinions, they are misleading.

Note: Now this was a first! When my team contacted iS Clinical to inquire about their animal testing status, we were told that they do not make this claim because they believe human beings are animals, and of course, their products are meant for people. We have no idea what that means.
