SHAISHAISHAI Repair Milky Urea Glow Bubble Serum 110ml is a Korean hydrating serum that transforms into micro-bubbles when shaken. Formulated with 20,000ppm high-purity urea to gently smooth rough texture while delivering deep, lasting hydration, plus 9 types of peptides to support firmness and elasticity. Niacinamide brightens dull tone and sodium hyaluronate locks in moisture for a dewy, bouncy glow. The lightweight milky texture layers without stickiness. Shake well to mix the cream and water layers, apply after cleansing and toning, and layer 2-3 times as an intensive glow mask when skin needs extra care. Suitable for all skin types, including sensitive skin.
