Kojic acid is a natural ingredient that is derived from fermented rice water, also known as sake. It is a by-product of this process and has been found to have potent skin brightening and lightening properties. The way in which it works is by inhibiting the production of melanin in the skin. Melanin is the pigment that gives skin its color, and an overproduction of it can lead to dark spots, age spots, and other forms of hyperpigmentation. By inhibiting the production of melanin, kojic acid can help to reduce the risk of hyperpigmentation while also managing existing dark spots or melasma. Additionally, Kojic acid can also be used to enhance the effectiveness of other lightening agents. However, it should be used with caution as it can cause irritation, redness and itching if used in high concentration or for a long period of time. It is recommended to patch test before using it all over the face, and to use it in lower concentrations if you have sensitive skin.
Kojic acid is a by-product of fermented rice water (sake), and exhibits potent skin brightening and lightening properties. Kojic acid has been shown to inhibit the production of melanin in the skin, making it effective in reducing the appearance of hyperpigmentation and dark spots. Studies have also shown that kojic acid can be an effective alternative to hydroquinone, a commonly used skin lightening agent, with less potential for side effects. However, it's always important to use Kojic Acid under the guidance of a dermatologist or skincare professional.
