Maya's read

Neutrogena Hydro Boost Water Gel is a moisturizer built around Glycerin and Hyaluronic acid. It leans strongest on hydration, barrier repair. Best suited to dry and dehydrated skin. Worth noting it contains fragrance, so reactive skin should patch-test.

Skip it if your skin reacts to fragrance: this one is scented.

Against the average moisturizer

HydrationBarrier repairBrighteningOil-controlAnti-aging
This productMedian moisturizer (11 in catalogue)

It scores lower than the median moisturizer on oil control, anti-aging, barrier repair and brightening.

On hydration 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.
