The formulation
Ingredient stack
Each ingredient is listed in descending concentration. Above the 1% line the order is regulated — below it, brands can list in any order.
Ingredients above the dashed gold line are dosed above 1% (the regulatory threshold) — these are what the formulation is really built on.
Originally a pharmaceutical antifibrinolytic, TXA is now one of the most effective topical ingredients for hyperpigmentation — including melasma and PIH. Inhibits keratinocyte-melanocyte signalling, blocking melanin overproduction. Distinct mechanism from Vitamin C means they can be combined for comprehensive pigmentation coverage. Particularly effective for melasma resistant to other treatments.
The most versatile and universally tolerated skincare active. Inhibits melanin transfer (fading dark spots), reduces sebum by up to 68%, strengthens the skin barrier via ceramide synthesis, calms inflammatory pathways to reduce redness, and visibly minimises pores over 4–8 weeks. Works at any pH and pairs with virtually every other active.
