What Is Kojic Acid?

Kojic acid is a chemical that is produced from several types of fungi. It can also be obtained from the Japanese rice wine (sake) and soy sauce and is used in the food industry for its preservation purposes. However, it is better known for its uses in the health and skincare world, and in this article, we will focus on that part.

Why Kojic Acid?


Kojic acid locally stops the production of melanin, a pigment that gives color to our hair, eye color, and skin. Because of this, the skin will become brighter, and it is the number one reason why people use kojic acid products.

Kojic acid aggressively exfoliates the top layer of the skin. The result of this is exposing the younger, brighter layer of the skin underneath - kojic acid is mainly used for its whitening effects. Contrary to this, if you do not exfoliate regularly, the dead cells will start piling up on the skin surface, and your skin will become darker. So, the kojic acid will do both things simultaneously - exfoliate and whiten the skin.

However, this compound has other benefits too. It will help you fight pimples, and even has a positive effect on acne scars. It will help you reduce or completely remove pigmentation and dark spots on your skin. It will also help you remove the dark spots on other parts of your body, not only your face.

The best thing about kojic acid is that it whitens your skin in a natural way, and it will give you a whiter, smoother and even skin tone, without looking awkward, or bleached.

Is Kojic Acid Safe?

Yes. Kojic acid has very few side effects, and unless you have ultra-sensitive skin, you will be just fine using it. Also, people who spend a lot of time in the sun should avoid using kojic acid products, especially in the morning.

Initially, you might feel some discomfort such as itching, dry skin, and even redness. But all this should go away once your skin gets used to it. Just make sure you put it on non-sensitive areas of your body first, since it is quite abrasive. Each one of us has different skin, and there are no one size fits all solutions when it comes to skincare products. That is why you should put small amount of kojic acid products first, on areas that are not visible, to see how your skin reacts. If it doesn’t get irritated, you can try it on other parts of your body too - face should be the last stop.
