Product details

A black dropper bottle of No.5+ Glutathione Vitamin Concentrated Serum on a cream table between golden serum bubbles and a sprig of lingonberries

Dark spot serum

A daily serum of glutathione, vitamin C, niacinamide and tranexamic acid that fades dark spots and brings back glow.

Numbuzin’s No.5+ serum is built for dull, uneven tone, dark spots and acne marks. Glutathione, the antioxidant Korea loves as a brightening supplement, works here alongside three forms of vitamin C, niacinamide and tranexamic acid to keep excess melanin in check, gently enough for everyday use.

How to use

After toner, every day

  1. 1

    Prep

    Cleanse and tone first. Numbuzin pairs it with its No.5+ toner as a booster.

  2. 2

    Drop

    Dispense a few drops of serum with the dropper.

  3. 3

    Pat

    Spread over the face, focusing on dark spots and marks, and pat gently until absorbed.

  4. 4

    Protect

    Follow with moisturizer, and sunscreen by day to keep new spots from forming.
