The Beauty of Joseon Glow Deep Serum combines 68% rice bran water and 2% alpha arbutin to target pigmentation and uneven skin tone. This lightweight serum provides brightening and moisturizing benefits while helping to inhibit melanin production for a more radiant complexion. Key features: • Contains 68% rice bran water for deep hydration • 2% alpha arbutin for brightening and evening skin tone • Lightweight, watery texture that absorbs easily • Enriched with traditional Korean herbal ingredients • Helps control hyperpigmentation • Suitable for all skin types Rice bran water has been traditionally used in Korean skincare since the Joseon Dynasty for its moisturizing and brightening properties. The alpha arbutin in this formula is known to be 10 times more effective than regular beta arbutin for inhibiting melanin production. For best results, use in the evening as alpha arbutin is sensitive to light and heat. Store in a cool, dark place and perform a patch test before first use if you have sensitive skin.
