tom-tit-tot Brightening X5 Serum

Dark spots are one of the most persistent skin concerns — and one of the most undertreated. Most brightening serums contain niacinamide at 2-3%, tranexamic acid at 1-2%, and call it a formula. tom-tit-tot took a different approach.

The Brightening X5 Serum contains Niacinamide at 50,000ppm — that is 5%, the concentration at which clinical studies show measurable inhibition of melanin transfer to skin cells. Tranexamic Acid follows at 30,000ppm — 3%, more than double the concentration found in most dedicated brightening treatments. Together they target hyperpigmentation through two completely different mechanisms simultaneously: Niacinamide interrupts the transfer of pigment to the skin surface, while Tranexamic Acid inhibits the activation of melanocytes at the source.

MELAZERO® V2 adds a third mechanism — a patented brightening complex developed specifically to address stubborn, treatment-resistant pigmentation. 10-Hyaluronic Acid delivers deep hydration across ten different molecular weights, ensuring every layer of the skin is plumped and radiant. NMN provides cellular energy support, accelerating the skin's natural renewal cycle so that results compound over time.

Hupura-MAC, Silver and Pearl complete the formula — adding anti-inflammatory, antimicrobial and luminosity-enhancing properties that address the secondary causes of dullness alongside the primary ones.

This serum is for anyone dealing with dark spots, post-inflammatory hyperpigmentation, melasma, sun damage or chronic dullness. For those who have tried brightening products and been disappointed. For those who want to understand why the concentration on the box matters — and what it actually feels like when a formula is built to work.
