Kojic Acid is a byproduct of the fermentation process of malting rice for sake production. In skincare, it is known for its ability to inhibit tyrosinase, the enzyme responsible for melanin production. This makes it effective in reducing the appearance of dark spots, age spots, and discoloration caused by sun damage or hormonal changes.
When used in skincare products, kojic acid can also help to even out skin tone and improve the appearance of hyperpigmentation. However, it is important to note that kojic acid can be irritating to some skin types and may cause allergic reactions in sensitive individuals.
It is commonly found in serums, creams, and lotions targeted at addressing hyperpigmentation and uneven skin tone. When using products containing kojic acid, it is crucial to follow the recommended usage and use sunscreen daily, as the ingredient can increase skin sensitivity to the sun.
It's important to note that kojic acid may not be suitable for all skin types, and individuals with sensitive skin should perform a patch test before incorporating products containing this ingredient into their skincare routine.
