<h4 class="dechead">On One Hand: Kojic Acid Can Lighten Skin Tone
Kojic acid has been shown to lighten the skin tone by inhibiting the enzyme that is responsible for the biosynthesis of the skin pigment called melanin. It is most often used in creams with concentrations of 1 to 4 percent. When compared to hydroquinone, another skin-lightening agent, it has been shown to be just as effective.
On the Other: Kojic Acid Can Cause Skin Irritation
In addition to irritation, kojic acid can cause irritant contact dermatitis, which is inflammation of the skin. It is a reaction caused by the epidermal cells as a result of chemical damage to the skin. To minimize irritation, kojic acid can be combined with a corticosteroid.
Bottom Line
When kojic acid is first being applied to the skin, it should be used in small amounts and at a low concentration. Although it is effective at lightening the skin, it can cause irritation if not used with caution.
