Some acids are magical for the skin as they can enhance the complexion and make it glow from within. Tranexamic Acid is one among them. It is a synthetic derivative of lysine with a structure partially similar to that of tyrosine. It has been proven to have an inhibitory effect on tyrosinase, which can prevent the formation of melanin and achieve whitening effects. At the same time, it can prevent the transmission of already produced melanin to surrounding cells, thus gradually eliminating pigment deposition.
