We’re still tracking retailers for this one. In the meantime:
A triple-threat brightening serum that stacks 20% niacinamide with 2% alpha-arbutin and glutathione — the kind of active concentration you'd expect from a clinical brand, not a $25 bottle. Tackles dark spots, enlarged pores, excess sebum, and early fine lines simultaneously. The texture is surprisingly lightweight for such a high-concentration formula, absorbs without pilling, and doesn't cause the flushing that cheap niacinamide serums are notorious for. If The Ordinary taught the world that niacinamide works, TIRTIR taught them it doesn't have to feel like a science experiment.
