How we score →Yay
5 experts · Moderate agreementWhat the gurus are saying
A stable form of vitamin C that doesn't oxidize is what wins gurus over, and it's less likely to sensitize than a sibling formula, so it suits skin that's touchy in winter. Praise centers on brightening and pigmentation, including under the eyes. The catch: quick results didn't show up for everyone, it's a water-free serum, and a skeptical camp found the formula disappointing.

Independent of what the gurus think, this is what the published research supports about the main active ingredients here.
Topical vitamin C is an antioxidant with reasonable evidence for dullness and uneven tone. It breaks down in light and air, so how a product is formulated and packaged matters as much as the percentage on the front.
