Key ingredients:
Hexylresorcinol - a phenolic lipid that modulates the melanogenesis pathway via tyrosinase and peroxidase inhibition; stimulation of the antioxidant glutathione, as well as the reduced transfer of melanosomes from the melanocytes to the keratinocytes.
Purified Licorice Root Extract - a highly purified form of licorice containing 95% glabridin, which is responsible for inhibiting hyperpigmentation. It reduces tyrosinase expression, tyrosinase activity, and melanocyte proliferation and migration while inhibiting melanin synthesis in melanocytes. It also inhibits an enzyme released after UV exposure or during inflammation to decrease tyrosinase expression and melanosome transfer.
Tranexamic Acid - a synthetic derivative of the amino acid lysine that helps inhibit melanin synthesis through plasminogen/plasmin pathways.
4-Butylresorcinol - a potent inhibitor of tyrosinase and peroxidase that leads to a reduction in melanin production
