High-concentration brightening and refined texture are the hallmarks of the TIRTIR Niacinamide 20% Serum, a potent formula designed to target stubborn blemishes and enlarged pores. That sophisticated blend uses a 20% concentration of niacinamide to unify skin tone, while alpha-arbutin and glutathione work in tandem to fade hyperpigmentation and dark spots. To balance this high-strength activity, the serum includes zinc PCA to soothe the skin surface and multiple forms of hyaluronic acid to ensure deep hydration. A small addition of retinol further supports the smoothing of fine lines, making this a comprehensive choice for those wanting a more resilient and radiant appearance. Its lightweight consistency absorbs quickly without leaving a tacky film, allowing for a smooth transition to the next step in a skincare routine. Why You Will Love It: Maximum Brightening Power: Combines 20% niacinamide and alpha-arbutin to significantly reduce the look of dark spots and uneven pigmentation.
