Retinol Serum by California Biology is a targeted nighttime treatment designed to support smoother, clearer, and more youthful-looking skin. Formulated with retinol, this serum helps improve the appearance of fine lines, uneven texture, and dullness while promoting skin renewal over time.
The lightweight formula absorbs quickly and works overnight to help refine the skin’s surface and enhance overall tone. With consistent use, skin appears firmer, smoother, and more balanced. Designed for gradual results, this serum fits easily into an evening skincare routine.
Housed in a green glass bottle to help protect potency and freshness, Retinol Serum delivers effective performance with a clean, refined feel.
