What the brand claims
In the brand’s own words, quoted as written.
“Marine Hyaluronics is a lightweight, water-based serum formulated to deliver intense hydration by targeting the skin's surface. It combines exopolysaccharides from skin-friendly marine bacteria, Hawaiian red algae, glycoproteins from Antarctic marine sources, micro-filtered blue-green algae, and several amino acids to support the skin’s natural moisture balance.”
