How we score →Mixed
9 experts · Strong agreementWhat the gurus are saying
This serum delivers solid hydration and a smooth, slippy texture that layers well, especially when applied to damp skin, though opinions split on whether it truly plumps. Most gurus praise the long-lasting moisture and short, clean ingredient list, making it friendly for sensitive skin; however, a few found it either too heavy, prone to pilling, or simply average in performance and not worth repurchasing. Those with dehydrated skin or anyone already using hyaluronic acid may find the polyglutamic acid a step up, but best patch-test first if you have a history of products pilling on you.

Vitamin E is an antioxidant, and it is often in a formula to keep the other ingredients stable rather than as the active itself. It pairs well with vitamin C, though on its own the evidence for visible change is limited.
