Short version

Story in brief

Anua's Niacinamide 10% + TXA 4% serum is priced at approximately $15-$25 USD for 30ml, which places it in the mid-range of niacinamide serums. It's more expensive than budget options like The Ordinary but more affordable than luxury Korean serums that can cost $40-70.

The serum combines niacinamide with tranexamic acid (TXA), a brightening agent that's popular in Korean skincare. This combination adds to the value proposition, as you're getting two active ingredients in one product.

The price is competitive when you consider the dual-action formulation. Compared to buying separate niacinamide and TXA products, the Anua serum offers good value.
