Transmalic acid, also known as aminocaproic acid, is an artificially synthesized amino acid. In recent years, it has gained significant attention in the field of medical aesthetics. As a protease inhibitor, it has a remarkable whitening effect.

The whitening mechanism of tranexamic acid mainly lies in two aspects: Firstly, it inhibits the melanin-enhancing factor group and reduces the activity of tyrosinase, thereby decreasing melanin production; Secondly, it can prevent the already formed melanin from transferring to the epidermis layer, effectively reducing melanin deposition. These effects make tranexamic acid an effective weapon against skin problems such as pigmentation and melasma.

In medical applications, tartaric acid is often used in combination with other whitening ingredients such as vitamin C ethyl ether and kojic acid to enhance the whitening effect. Additionally, tartaric acid is widely employed in medical fields such as surgery and internal medicine, exerting its pharmacological effects of hemostasis and anti-inflammation.
