Kojic Acid Identification

Kojic acid is an organic acid that can be isolated from some fungal cultures, including aspergillus and penicillium fungi. Kojic acid is also a byproduct of fermenting reactions in many Asian foods (including sake). Kojic acid has a number of useful properties, including its ability to bind various metal ions, preventing them from engaging in other chemical reactions (a process known as chelation). Kojic acid can also be used to prevent the browning of vegetables. Kojic acid is most commonly used in dermatological settings, where it can be used (along with other compounds, such hydroquinone and glycolic acid) as a skin whitener; it is used in many chemical peels designed to lighten the skin.

Kojic Acid Mechanism

Kojic acid is commonly used as a skin whitening agent, due to its ability to prevent the formation of melanin, which is the primary skin pigment. This is thought to be a result of kojic acid's ability to bind copper. Copper is needed for an enzyme, known as tyrosinase, to work. Tyrosinase is a protein that breaks down tyrosine, an amino acid. The products of this breakdown stimulate melanocytes, small cells that that produce melanin, which causes pigmentation of the skin. As a result, application of kojic acid can effectively treat hyperpigmentation; its effects have been documented in a 1999 study performed by Dr. Kim in Singapore, and published in the Journal of Dermatological Surgery.

Kojic Acid Side Effects

People often wonder if kojic acid can cause acne. In short, the answer is no, it cannot. In fact, kojic acid is often used in the treatment of acne scars, as they are commonly darker than the rest of the skin, and respond well to kojic acid treatment. The main effects of kojic acid are redness and stinging of the affected areas. Because kojic acid is slightly caustic, it can irritate the skin and make it more sensitive to sunlight. As a result, areas that have been treated with kojic acid may develop some redness and tenderness after the treatment, and this may be mistaken for acne. However, there is no evidence that kojic acid clogs pores or causes acne.
