A hydrating serum is a concentrated skincare product designed to deliver moisture directly to the skin cells. Unlike moisturizers, which often form a barrier on the skinโs surface to lock in hydration, serums penetrate deeper, nourishing skin from within. Most hydrating serums, including Elixire Belle's, rely on powerful humectants like hyaluronic acid, glycerin, and aloe vera to draw moisture into the skin.
These serums are typically water-based, making them lightweight and fast-absorbingโperfect for layering under moisturizers and makeup. Whether you have dry, oily, combination, or sensitive skin, a well-formulated hydrating serum can provide the moisture balance your skin craves.
