5% Tranexamic Acid
Interrupts the inflammation-to-melanin signal. The only ingredient with peer-reviewed data on PIH specifically.
7% Niacinamide
Blocks pigment transfer to the skin surface and rebuilds the barrier so darkening doesn't return.
2% Alpha-Arbutin
A natural tyrosinase inhibitor — slower than hydroquinone, with zero rebound.
