There are many ways you can get white and bright skin, from starting to use face creams sold on the market to consulting a specialist doctor. One of the lightening ingredients that is believed to be quite effective is kojic acid. However, is it true that this ingredient is effective and has been proven safe for the skin? Find out here, yeah.
What is kojic acid?
Kojic acid is known as a powerful ingredient for lightening the skin. This compound is made of several types of mushrooms. Acetobacter, Penicillium, and Aspergillus are types of fungi that are usually the ingredients for making kojic acid. This kojic acid is a by-product when certain foods are fermented, such as Japanese sake, soy sauce, and rice wine.
How does it work?
This compound is used as a skin lightening agent because of its effect on proteins known as tyrosinase. According to Dr. Alaina J. James at the University of Pennsylvania Medical Center, kojic acid works by preventing a specific tyrosinase function called chatecolase. This chatecolase enzyme plays a role in making melanin compounds.
Thus, by inhibiting the ability of the tyrosinase protein to make melanin, kojic acid is able to prevent skin pigmentation which can help brighten skin tone. As is known, melanin is a color pigment that affects hair, skin, and eye color.
Products containing kojic acid
Kojic acid is already widely used in various cosmetic products. For cosmetic ingredients that are used as skin lightening, the permissible concentration is usually one percent or even less. This compound is usually used for cosmetic products such as serum, cream, cleanser, and soap for the face.
Some products such as soap and cleansers are usually recommended to be washed immediately after use. Creams and serums are designed to be absorbed in the skin even though kojic acid generally has a relatively low absorption rate on the surface of the skin.
Some products such as face masks are formulated to be used on certain occasions. While creams and cleansers are indeed made to be used every day. Therefore, the content in each cosmetics has been adjusted to the type of use so that it is safe to use. This product is generally used for face and hands.
