Niacinamide Serum by California Biology is a daily treatment designed to help balance, smooth, and refine the appearance of the skin. Formulated with niacinamide, this serum supports a more even-looking complexion while helping reduce the appearance of enlarged pores and uneven texture.

The lightweight, fast-absorbing formula delivers hydration without heaviness, making it ideal for layering into any skincare routine. With consistent use, skin appears calmer, clearer, and more balanced.

Packaged in a blue glass bottle to help protect freshness and potency, Niacinamide Serum offers reliable performance with a clean, modern feel.
