Numbuzin – No.5+ Glutathione Vitamin Concentrated Serum – 30 ml

No.5+ Glutathione Vitamin Concentrated Serum is a daily anti-dark spot serum designed to target brown spots, post-blemish marks, and dull or uneven skin tone. Its formula combines a brightening and antioxidant complex—Glutathione, Vitamin C (including 3-O-Ethyl Ascorbic Acid), 5% Niacinamide, and 4% Tranexamic Acid—to visibly reduce hyperpigmentation while remaining gentle on sensitive skin.

Soothing and barrier-supporting ingredients (Panthenol, Ceramide NP, Beta-Glucan, and Allantoin) enhance comfort and strengthen the skin barrier, leaving the complexion brighter, more even, and balanced over time. The lightweight texture absorbs quickly without stickiness, making it easy to layer within your skincare routine.
