numbuzin No. 5+ Vitamin Concentrated Serum

A brightening Korean serum formulated with glutathione, vitamin C, niacinamide, and tranexamic acid to reduce dark spots and improve overall skin radiance.

Product Overview

numbuzin No. 5+ Vitamin Concentrated Serum is a Korean brightening serum designed to improve uneven skin tone and reduce the appearance of dark spots. Developed by the skincare brand numbuzin, this serum focuses on addressing hyperpigmentation, acne marks, and dull skin through a concentrated blend of antioxidant and brightening ingredients.

Hyperpigmentation can occur due to sun exposure, acne scars, hormonal changes, and inflammation. Skincare products that combine multiple brightening ingredients can help support the skin’s natural renewal process and gradually improve overall skin tone.

This serum features a combination of glutathione, niacinamide, vitamin C, and tranexamic acid. These ingredients are widely used in skincare for their ability to target melanin production and improve skin brightness. (numbuzin)

With its lightweight texture and fast absorption, the serum can be easily layered within a daily Korean skincare routine. Many users incorporate it as a treatment step to support clearer, brighter, and more even-toned skin.
