Sodium Hyaluronate Crosslinked (Filler Grade)
Crosslinked Sodium Hyaluronate is a chemically cross-linked form of hyaluronic acid where HA chains are interconnected via BDDE or other crosslinking agents to create a stable gel matrix with greatly extended residence time in tissues compared to non-crosslinked HA. It provides superior volumizing, plumping, and long-lasting moisturization effects in topical cosmetics and is the same technology used in injectable dermal fillers. Used at 0.1–2% in plumping serums and high-performance skin-padding creams.
