Volume 30ml 1.01 fl. oz. Exp 2025 Creates a glass-like, skin-perfecting finish that looks beautiful both on its own and underneath makeup. From Slurp: "Hydromer is a liquid bandage made of Jeju algae polymers developed to prevent flare ups and congestion triggered by external irritants while priming skin for smoother, longer lasting sunscreen / makeup finish with a dewy undertone." "Retouch imperfections Moisture lamination & optical filtration Hydromer forms a breathable film across skin composed of over 60% Jeju Island algae polymers that instantly accumulates a surge of plumping moisture while trapping it in—resulting in minimized pores all day long, without pore-clogging silicones. In addition, Hydromer reduces saturation of blemishes (red, purple and dull hues) readable by the human eye by increasing the amount of light being absorbed and refracted back from skin’s surface similar to a filter—rendering clearer, smoother looking skin. Makeup-polymer unification & oxidation suppression Hydromer is a thermoreversible formula. It applies viscous and melts down with the warmth of your skin’s temperature, gripping sunscreen / makeup on before settling skin-tight. In addition, Hydromer reduces skin’s natural sebum to come in contact with air, sunscreen and/or makeup which minimizes oxidation - the chemical reaction that causes clogged pores, smudging and cakeyness. Altogether nurturing higher performing sun protection and longer lasting no-makeup."
