TIRTIR Niacinamide 20% Serum 30 ml

A concentrated serum with 20% niacinamide, created for skin with dark spots, post-acne marks, visible pores, excess sebum and uneven tone. The formula combines niacinamide, alpha-arbutin, glutathione, Zinc PCA, hyaluronic acid and retinol to support a clearer, smoother and more balanced-looking complexion.

The texture is lightweight, spreads easily and absorbs comfortably without leaving a heavy feel. The serum is suitable for skin that looks dull, congested or uneven, but it should be introduced gradually because the formula contains a high concentration of niacinamide and retinol.
