The Numbuzin No.5 Vitamin Concentrated Serum is an intensive brightening ampoule designed to restore your skin’s natural radiance while targeting dullness, dark spots, and uneven skin tone. This concentrated serum delivers a powerful glow-boosting effect, helping the complexion look clearer, fresher, and more luminous with continued use.

Formulated with a blend of proven brightening ingredients, including glutathione, niacinamide, and alpha-arbutin, the serum helps reduce the appearance of hyperpigmentation and supports a more even skin tone. Glutathione is valued for its antioxidant benefits and tone-enhancing properties, while niacinamide hydrates and helps strengthen the skin barrier for a healthier-looking complexion. Alpha-arbutin contributes to visible brightening by addressing discoloration and helping fade dark spots over time.

To keep the formula gentle and suitable for daily use, the serum is enriched with soothing plant-based extracts such as sugarcane, turmeric root, and mushroom, which help minimize irritation and support skin comfort. Lightweight yet concentrated, the Numbuzin No.5 Vitamin Concentrated Serum is an ideal choice for anyone looking to achieve a brighter, more even-toned glow without compromising hydration.
