The gurus in the yes camp found real things to like here, the kind of everyday wins that keep a serum in someone's routine. The gurus who landed on no weren't dismissing it outright either. They simply didn't get the same results, or ran into something about how it wore that kept them from recommending it.
With 7 takes on one side and 6 on the other, neither camp gets to speak for the product. The fairest read is that both sets of experts are describing something real, just from different experiences with it.
Why are the experts so divided on it?
A split this close usually isn't a sign that something is wrong with a product. It is often a sign that the product is doing something specific enough that it lands differently depending on the skin it meets. Vitamin C serums are a good example of why: vitamin C is an active, and actives don't behave the same way on every skin type. For some people it sits well and brightens nicely, and for others it can feel less comfortable or simply not show the results they were hoping for.
Expectation and technique play a part too. Someone expecting a dramatic change may judge the same serum more harshly than someone who was just looking for a gentle addition to their routine. None of that makes either side wrong. It just means the experts were weighing in from different starting points.
So should you try it?
Because this one genuinely works for some people and not others, the sensible approach is to treat it as a personal experiment rather than a sure thing either way. It is worth patch testing first, especially for anyone with sensitive skin, and introducing it on its own rather than layering it in alongside a bunch of new products at once. That way, if something does happen, it is clear what caused it.
From there, it is a matter of giving it a few weeks before deciding. Vitamin C serums tend to show their effects gradually, and a quick first impression will not tell the same story as a full trial run. With a coin flip verdict like this one, patience and a bit of self observation matter more than they would for a product the experts agree on.
