What it delivers
How it feels A light, fast-absorbing texture that layers cleanly under the rest of your routine, with no greasy film. (estimated from the formula)
What's in it that matters
Classic humectant with strong evidence for improving skin hydration and supporting barrier when combined with emollients.
Water-binding molecule that increases hydration; works best under occlusive/emollient layers to reduce evaporation.
Crosslinked sodium hyaluronate that forms a hydrated gel matrix at the surface. Used in serums for longer lasting hydration that visibly softens fine lines while it is in place.
Humectant and soothing ingredient that helps calm irritation and supports barrier repair and recovery.
Short chain diol that works as a light humectant, co solvent and preservative booster. It keeps a formula less sticky and microbially stable while hydrating the outer layers.
How to use it
Morning and/or night, after your thinner water-based steps and before heavier creams.

Against the average serum
It scores lower than the median serum on anti-aging and brightening.
On hydration, barrier repair and oil control it is level with the median, so that is not what sets it apart.
A median, not an average: one unusual formula should not move the middle. The numbers are the same 0 to 10 reads the comparison pages use.
