Hyaluronic Acid & Retinol Serum by California Biology is a dual-action formula designed to hydrate, smooth, and visibly refine the appearance of the skin. Combining the moisture-binding power of hyaluronic acid with the skin-renewing benefits of retinol, this serum supports a balanced approach to hydration and renewal.

The lightweight, fast-absorbing formula helps improve the look of fine lines, uneven texture, and dryness while keeping skin comfortably hydrated. With consistent use, skin appears smoother, plumper, and more refreshed without feeling heavy or greasy.

Packaged in a blue glass bottle to help protect potency and freshness, Hyaluronic Acid & Retinol Serum delivers targeted performance in a clean, modern skincare essential.
