No.5 Glutathione Vitamin Concentrated Serum - 30ml

Numbuzin - No.5 Glutathione Vitamin Concentrated Serum - 30ml is a K-beauty face serum with title-confirmed glutathione and vitamin positioning. The assigned data confirms the Numbuzin brand, Face Serum category, 30ml size, and No.5 product line naming, so the copy stays focused on a concentrated serum step for routine care.

Why It Stands Out

The No.5 naming and glutathione vitamin title make this listing more specific than a general hydrating serum. It is a targeted product for shoppers who want a glow-oriented serum format from Numbuzin.

Best For

Best for K-beauty users building a serum step around radiance, dull-looking skin, or ingredient-led brightening interest without switching to a moisturizer or toner.

How to Use

Apply after cleansing and toner, then seal with moisturizer. Use sunscreen during daytime routines, especially when using skincare aimed at a brighter-looking complexion.

Benefits

• Concentrated serum format supports targeted skincare.
• Glutathione and vitamin positioning is confirmed in the title.
• 30ml size fits regular face-serum use.
• No.5 product name helps shoppers identify the exact Numbuzin line.

Good to Know

Introduce new serums gradually and patch test first if your skin reacts easily to active or brightening-care products.
