The protective layer that locks in hydration and supports the barrier. Gesso is where hydration is sealed and the skin barrier is supported. If your skin feels dry, reactive, prone to visible redness, or loses moisture throughout the day, this is the layer that helps maintain hydration and strengthen the skin barrier. Applied after Canvas and Composition or on its own, Gesso helps seal in hydration while continuing the gentle daily renewal that defines every layer of the Collage system. Most heavy creams sit on the surface and feel greasy or clogging. Gesso works differently. Unlike traditional balms, Gesso creates a breathable seal that helps reduce moisture loss while fully absorbing into the skin. Powered by niacinamide, high-molecular-weight hyaluronic acid, and botanicals, it helps support the skin barrier, maintain hydration, and keep skin feeling calm, balanced, and comfortable. ✔ Helps seal in hydration to reduce moisture loss throughout the day✔ Supports the skin barrier to help reduce sensitivity and visible redness✔ Supports smoother texture and a more even-looking complexion✔ Helps maintain hydration without heaviness or buildup✔ Can be used as a final layer or wherever skin needs extra support
