This brightening serum is formulated with 5% niacinamide and 1% undecylenoyl phenylalanine to target uneven skin tone, dark spots, and dullness. Niacinamide helps improve skin barrier function, reduce redness, and enhance overall texture, while undecylenoyl phenylalanine works to visibly fade pigmentation and prevent new discoloration. The lightweight, fast-absorbing formula is non-comedogenic and suitable for all skin types, including sensitive and acne-prone skin. With consistent use, it promotes a more radiant, even-toned complexion without irritation. Free from parabens, sulfates, and artificial fragrances, it is safe for daily use. This serum fits easily into any skincare routine and can be layered with other products. For best results, apply to cleansed skin and follow with a broad-spectrum sunscreen during the day.
