What the brand claims
In the brand’s own words, quoted as written.
“Hydrabio Hyalu+ serum is formulated to support the skin’s natural hydration mechanisms through a targeted blend of biomimetic ingredients. It combines low molecular weight hyaluronic acid, niacinamide, carnosine, and Hyalu+ Technology—a proprietary mix of high molecular weight hyaluronic acid and a self-rehydrating sugar—to deliver immediate and lasting moisture, help reduce visible signs of aging, and strengthen the skin barrier.”
