Niacinamide, also known as vitamin B3, is a water-soluble vitamin that has been shown to possess anti-inflammatory, antioxidant, and depigmenting properties. At a concentration of 10% in the serum, niacinamide can help improve skin barrier function, reduce redness, and regulate sebum production. Its ability to inhibit the transfer of melanosomes within the skin cells contributes to its skin-brightening effects. Tranexamic Acid (TXA), at a concentration of 4%, is a synthetic derivative of the amino acid lysine. TXA is known for its anti-inflammatory and anti-hyperpigmentation properties.

The pH of the ANUA Niacinamide 10 + TXA 4 Serum is formulated to be within the optimal range for skin compatibility, ensuring effective delivery of the active ingredients. The serum has a lightweight and non-greasy texture, allowing for easy absorption into the skin without leaving a residue. Overall, the combination of niacinamide and TXA
