Hydrobiome Serum

Pentylene Glycol is a plant-derived diol that functions as a humectant and solvent to attract moisture, stabilize emulsions and boost preservative performance in skincare formulations. Its antimicrobial properties and low molecular weight support hydration, texture enhancement and ingredient delivery without irritating sensitive skin.

Sodium Hyaluronate is the sodium salt of hyaluronic acid that penetrates deeply to bind moisture, plump skin, and smooth fine lines. It forms a protective, lightweight film to reduce water loss and calm inflammation, making it an essential humectant for dry, sensitive, and aging skin in serums, creams, and masks.

Propanediol is a corn-derived humectant and solvent that boosts hydration, smooths texture, and supports the skin barrier with a lightweight, non-sticky feel. It enhances ingredient penetration, improves preservative efficacy, and stabilizes formulations, serving as a sustainable alternative to propylene glycol for all skin types.
