Anua Niacinamide 10% + TXA 4% Serum is a concentrated brightening treatment designed to target the appearance of uneven pigmentation, dark spots and post-blemish marks. Niacinamide helps support the skin barrier, improve the appearance of uneven tone and balance excess oil, while tranexamic acid provides targeted care for visible pigmentation. Together, these ingredients help create a more even, radiant and balanced-looking complexion with consistent use. The serum is suitable for normal, combination and oily skin types, as well as dry skin concerned with uneven tone and pigmentation. After cleansing and toning, apply a few drops evenly across the face, focusing on areas with visible dark spots or uneven pigmentation. Gently pat until absorbed and follow with moisturiser. It can be used in the morning and evening, but always apply sunscreen during the daytime when using brightening treatments to help protect the skin from UV exposure.
