This serum is designed for those with concerns about pigmentation and uneven skin tone. Containing 68% rice bran water and 2% alpha arbutin, it helps to improve skin tone to become brighter and healthier. In the Joseon Dynasty, rice bran water was used like the toner of today, and was called Beauty Water, used for beautiful skin. Rice bran is rich in amino acids and minerals, helping to moisturize dry skin. Alpha-Arbutin is a safe, brightening ingredient extracted from plants such as lingonberries and blueberries. It helps prevent skin pigmentation by inhibiting the production of melanocytes.
