Beauty of Joseon Glow Deep Serum Rice + Alpha Arbutin is a serum suitable for skin with blemishes, uneven tone or texture, dull skin, mature skin, and/or acne-scarred skin. Formulated with 68% rice bran water and 2% alpha arbutin, which give the skin a brighter, healthier appearance. Rice has played a very important role as a staple food and skincare ingredient in Korean history. In the Joseon Dynasty, rice bran water was used as a toner and was called Beauty Water. Rice bran is rich in amino acids and minerals, which improve hydration levels in dry skin. Alpha arbutin works by inhibiting tyrosinase activity, which limits melanin production in the skin. Additionally, it is also known to have a 10 times greater effect than regular beta-arbutin. This ampoule hydrates and evens out skin tone, restoring a radiant, healthy-looking, and blemish-free appearance. Cruelty-free, free of phenoxyethanol, mineral oil, parabens, sulfate, PEG, EU allergens, artificial fragrances and colors, and essential oil. Formulated with EWG-certified ingredients and suitable for vegan use.
