Numbuzin No.5+ Glutathione Vitamin Concentrated Serum is a targeted serum designed to improve the appearance of dark spots, hyperpigmentation, and uneven skin tone. The vitamin-rich formula combines 5% niacinamide, 4% tranexamic acid, glutathione, and vitamin C with a high concentration of lingonberry extract for clearer, more even, and radiant skin.

Niacinamide and tranexamic acid work together to improve skin tone uniformity and reduce the visibility of pigmentation, while glutathione and vitamin C provide antioxidant support. The formula also contains alpha-arbutin and bisabolol, which complement the serum's targeted treatment for uneven skin tone and visible spots.

With 60.4% lingonberry extract, the skin receives a rich source of plant-based antioxidants. Together with vitamin E, coenzyme Q10, and alpha-lipoic acid, this helps to protect and nourish the skin. 5% panthenol, beta-glucan, allantoin, and hyaluronic acid provide hydration and contribute to a comfortable and balanced skin feel.

The lightweight texture absorbs quickly, leaving the skin soft, supple, and glowing. The serum is suitable for all skin types and is specifically developed for skin that appears dull, uneven, or marked by dark spots and blemishes.

Numbuzin states that in clinical tests, the product helped even out skin tone by 18.90% and reduced dark spots by 9.65% after four weeks.
