What the gurus are saying

In a lightweight gel texture instead of a typical cream, this serum delivers ceramides, cholesterol, and fatty acids, the three barrier essentials. It offers serious hydration in a breathable formula that feels refreshing and soothing on oily and combo skin, particularly in humid or summer weather. That balance of calm and hydration without weight is rare in ceramide-rich products.

    "I love this texture. It just sinks so deep in the skin with refreshing, cooling like hydration deep down within.

    What the evidence says.

    Independent of what the gurus think, this is what the published research supports about the main active ingredients here.

    Niacinamide

    Niacinamide has evidence behind it for redness, uneven tone and supporting the skin barrier, and it is usually well tolerated even by skin that reacts to most things.

    Source: DermNet

    Urea

    Urea both holds water in the skin and gently loosens dead surface cells. At higher strengths it has good evidence for very dry or thickened skin.

    Source: DermNet

    Ceramides

    Ceramides are part of the skin's own barrier, and moisturisers built around them have evidence for holding water in and settling the tightness and flaking that come with a damaged barrier.
