Discovered in the 1950s, tranexamic acid is a substance closely related to the amino acid lysine, used in medicinal treatments for its fibrinolysis inhibitory action. It was only in 2009 that it was recently authorised and introduced into the composition of beauty products by the cosmetics commission. Through its depigmenting action, this acid visibly fades the appearance of several types of skin hyperpigmentation (melasma, post-acne marks, sun spots, etc...) and thus lightens the complexion, by preventing the formation of new melanin. Research has even shown that the effectiveness of tranexamic acid could rival that of hydroquinone. It is also sought after for its anti-inflammatory function.
