Tranexamic acid is a substance that inhibits the action of an enzyme known as plasminogen, which normally binds to clots to destroy them and prevent them from forming a thrombosis, for example. However, in people with diseases that make blood very thin, plasminogen may also prevent the formation of clots during cuts, for example, making it difficult to staunch bleeding.
In addition, this substance also appears to prevent the normal production of melanin and therefore can be used to lighten some skin blemishes, especially in the case of melasma.
Due to its double action, this substance can be found in the form of tablets, to prevent bleeding, or in the form of cream, to help lighten blemishes. It can also be used as an injection in the hospital to correct emergencies related to excessive bleeding.
