HYA + NIA Serum, featuring Hyaluronic Acid + Niacinamide, is a lightweight, hydration-focused formula designed to plump, smooth, and rebalance the appearance of the skin. Powered by a combination of hyaluronic acid + niacinamide, this serum helps attract and retain moisture while supporting a more even, refined-looking complexion.

Hyaluronic acid works to deeply hydrate and visibly plump the skin, helping reduce the appearance of dryness and fine lines. Niacinamide helps balance oil production, minimize the look of enlarged pores, and improve uneven skin texture, leaving the skin looking smoother and clearer.

The fast-absorbing, non-greasy texture delivers lasting hydration without heaviness, making it ideal for all skin types and easy to layer with other skincare products. With consistent use, skin appears more hydrated, balanced, and visibly refreshed, revealing a healthy, radiant glow.
