"Minimalist Tranexamic 3% Serum is a powerful serum to effectively diminish the appearance of melasma, PIE, PIH and hyperpigmentation. With the power of 3% tranexamic acid and 1% hydroxyphenoxy propionic acid, this serum inhibits melanin transfer with great efficacy and prevents UVB damage.
The science behind this product: Tranexamic acid is a new generation molecule that inhibits melanin synthesis by interfering with the interaction between melanocytes and keratinocyte through inhibition of the plasminogen/plasmin system. External skin disruptors, such as UV light or injuries (like acne), cause the keratinocytes in our skin to produce plasminogen, that further start several processes like inflammation, increased tyrosinase activity, melanocyte differentiation, and transfer of melanosomes to upper skin layers. Tranexamic acid decelerates these processes by interfering with plasmin activity, and hence, in turn, indirectly inhibiting melanogenesis. Studies have shown that tranexamic acid, when applied topically, shows results similar to hydroquinone in the reduction of hyperpigmentation. It is also one of the most proven ingredients for the treatment of melasma.
