The whitening mechanism of Tranexamic acid is to simultaneously and rapidly inhibit the activity of tyrosinase and melanocytes,and to prevent aggregation of melanin,as well as to block the process of melanin deterioration due to ultraviolet irradiation. 
Tranexamic acid is a protease inhibitor that inhibits the catalysis of proteases on peptide bond hydrolysis,thereby preventing the activity of enzymes such as inflammatory proteases,and stoping the disorder of epidermal cell functioning in the dark spot and restraining melanin enhancing factor group,in order to completely cutting off the process which melanin formed by way of ultraviolet irradiation.The dark spots are no longer thickened,enlarged and increased,so that the pigmentation of the skin can be effectively prevented and improved.

Tranexamic acid has a fourfold whitening mechanism:

1.Rapidly inhibits the activity of tyrosinase and melanocytes while blocking melanin aggregation.

2.Effectively slow the accumulation of inflammation-induced melanin in the deep skin.

3.Effectively prevent the secondary oxidation of melanin.

4.Effectively reduce the precipitated melanin and promote the separation of the produced melanin.
