What Is Kojic Acid?

Kojic acid is a godsend for anyone who’s battling dark spots and dull skin. It is a wonder ingredient present in skin brightening creams and serums, and I will tell you why. What is an agent that is extracted from different types of fungi, especially the different strains of Aspergillus (a kind of fungus). It was first discovered in 1907 and was extracted from a strain of Aspergillus called Aspergillus oryzae grown on steamed rice. The name kojic acid is taken from the Japanese term “koji,” meaning “steamed rice.” It is widely used in cosmetic and skin care products as a whitening and brightening agent .

How It Works?

Kojic acid is a key ingredient in many skin brightening creams, gels, and serums. The Scientific Committees on Consumer Products (SCCP) approved using kojic acid in skin care products at a concentration of 1% or less.

You will come across soaps, cleanser, serums, creams, and lotions containing different concentrations of kojic acid. You need to use the product as per the instructions provided by the manufacturer. While you have to wash off soaps and cleansers immediately after application, you can leave serums, creams, and lotions on overnight for better absorption. Let’s now understand how kojic acid functions.

Kojic acid brightens your skin by inhibiting melanin production. Melanin is the pigment that colors your skin, eyes, and hair. Overproduction of melanin often gives you dark spots and uneven skin tone. Your body produces melanin with the help of an amino acid called tyrosine. Kojic acid inhibits the function of tyrosine, which, in turn, inhibits melanin production.

2. It Has Anti-Aging Effects

Now that sounds exciting! Kojic acid creams and products not only reverse sun damage but also reduce wrinkles and signs of aging. Kojic acid inhibits the action of tyrosinase, which is responsible for melanin production and the skin aging process.

Although the antibacterial properties of kojic acid are not extraordinarily powerful, it is pretty effective against several strains of bacteria and can inhibit their growth even when used in small dilutions.

4. It Has Antifungal Properties

Kojic acid also has antifungal properties. It was found to have an inhibitory effect on certain strains of fungi and is extremely helpful in treating yeast infections, such as athlete’s foot or ringworm and candidiasis.
