皮膚透過紫外線的照射之下，會釋放出前列腺素，前列腺素會刺激黑色素細胞的生成，並同時促進酪胺酸酶活性，加速黑色素生成並儲存於黑色素細胞的黑色素小體中，當黑色素小體與角質細胞融合後，會逐漸上移至皮膚表面，造成皮膚變黑。而傳明酸會抑制前列腺素生成，間接降低酪胺酸酶活性。在醫學上常作為凝血成份，外用時能抑制黑色素形成及防止色素斑的形成，阻斷黑色素傳遞之路徑，衛生署規定濃度限量為 2％-3%，產品需辦理含藥化粧品查驗登記.
The skin releases prostaglandins under ultraviolet radiation. Prostaglandins stimulate the production of melanocytes, and at the same time promote tyrosinase activity, accelerate the production of melanin and store it in the melanocytes of melanocytes. After fusion with keratinocytes, it will gradually move up to the surface of the skin, causing the skin to darken. Tranexamic acid inhibits prostaglandin production and indirectly reduces tyrosinase activity. It is often used as a blood coagulation component in medicine. It can inhibit the formation of melanin and prevent the formation of pigment spots when used externally, and block the path of melanin transmission. The Department of Health stipulates a concentration limit of 2%-3%. The product needs to go through the inspection and registration of medicated cosmetics.
