Kojic Acid History and Background

History and Background

The skincare and cosmetic market are currently full of many organic products and practices. 

However, despite the vast number of different products on the market, Kojic acid is still in the spotlight, as it is one of the best. 

This natural ingredient helps to resolve various skin conditions, including hyperpigmentation, scarring, discoloration, dark spots, melasma, blemishes, and much more. 

Kojic acid has been around for a very long time, and it has been working wonders since then. 

Here is a brief of the history and background of the Kojic acid soap.

Overview of Kojic Acid

Kojic acid is produced naturally by different kinds of fungi. The fermentation of certain food types produces this acid, such as soy, rice wine, and Japanese sake. 

Kojic acid is highly beneficial to the human skin. One of the major functions of Kojic acid is that it helps to prevent the production of tyrosine.

Tyrosine is the amino acid required in the production of melanin, and melanin affects the color of the eyes, hair, and skin. 

Since it helps to inhibit and prevent melanin formation, Kojic acid can have a lightening effect.

This acid is much better, safer, and a natural alternative to hydroquinone.  

Furthermore, it is excellent for people struggling with scars, skin discoloration, and hyperpigmentation. 

And it helps to combat issues such as acne scars and sun-spots.

Saito discovered the Kojic acid in Japan back in 1907. He isolated the new compound he found from mycelium of the fungus Aspergillus oryzae grown on steamed rice, which means Koji in Japanese. 

Yabuta was the one who gave the organic compound the name “Kojic acid” in 1913.

Forms and Usage of Kojic Acid

This natural ingredient’s primary use is to treat a wide range of different cosmetic and skin conditions. It has a variety of use cases beyond cosmetics and skincare. 

Kojic acid is approved and safe for cosmetic products, with one percent (or lower) concentration.

You can find this acid in different cosmetic products like creams, powders, soaps, cleansers, serums, and more. 

It comes in different forms, and the application differs from one product to another. 

For instance, you should mix Kojic acid-infused powder with water or lotion, but this depends on the manufacturer’s instruction. 

On the other hand, you need to wash off other products like soaps and cleansers immediately after applying them.

You can leave other products like creams and serums on the body for the skin to absorb. 

Nevertheless, the absorption rate of this acid beneath the surface of the skin is somewhat lacking. 

Some products containing Kojic acid are designed for everyday use, while others are ideal for occasional use. 

For instance, you can use creams and cleansers daily, but products such as face masks are for occasional use. 

The usage also differs from one product to another, as some products are ideal for the face only while others are ideal for all non-sensitive parts of the body.
