Shiseido's Bio-Performance Skin Filler Serums - Refill combines multiple forms of hyaluronic acid, including sodium hyaluronate and high molecular weight hyaluronic acid, with MolecuShift Technology and collagen-supporting peptides to visibly plump, firm, and deeply hydrate. Used as the two-step Morning Full Expansion and Evening Infill duo (two 30 mL serums), it helps smooth fine lines, restore the look of volume, and improve skins bounce and resilience with consistent use.
The result is skin that looks fresher, more cushioned, and more structured over time, with hydration that feels locked in rather than temporary. Designed as a refill, it offers the same performance benefits while cutting plastic waste by up to 74% for a more practical, eco-conscious way to maintain the regimen.
