Bio-Performance​ Skin Filler​ Day & Night Serum Refill 2-Piece Set

SHISEIDO’s original MolecuShift Technology successfully shrinks hyaluronic acid molecules, for precise delivery. Infill Serum (for night) targets a firm, resilient look, with the technology that sends micro hyaluronic acid molecules into the deeper layers. Full Expansion Serum (for day) targets a lifted look, with the technology that reshape those molecules to their original size in the skin―for creating an extra moisture-retaining layer that helps push skin up. Experience an advanced shift—in the size of hyaluronic acid molecules. SHISEIDO’s original approach fills skin with new life, as two advanced serums perform as partners to fill the inner layer and bring out skin’s volume. Made in Japan. Add to any skincare routine. See a dramatically improved moisturizing effect when used with ULTIMUNE and a cream category product. Infill Serum (for night): Micro size HA molecules are able to penetrate deep into the surface layer due to their smaller size. During the night, they take their time to penetrate deep within. Full Expansion Serum (for day) Micro size HA molecules are reverted to their original size in skin. The surface layer becomes infused with HA, for a plumped look as if skin is pushed up from within.
