    Why it works

    Foile Skin Sponge Serum is a lightweight water-based serum that hydrates, soothes and supports moisture balance. It layers easily under moisturiser or oil and helps skin feel fresh, soft and comfortable.

    Humectant hydration

    Glycerin and sodium hyaluronate attract water into the skin. This helps skin look plumper and feelmore hydrated.

    Soothing support

    Aloe, panthenol and cucumber help calm dryness and discomfort. Skin feels softer and less reactive.

    Lightweight moisture balance

    The water-based texture adds hydration without heaviness. This makes it easy to use across all skin types.
