numbuzin No.5 Glutathione TXA Dark Spot Ampoule 10.7g — Tranexamic Acid & Niacinamide Brightening Serum

numbuzin No.5 Glutathione TXA Dark Spot Ampoule is a concentrated Korean-style ampoule formulated with glutathione, tranexamic acid, and niacinamide to help visibly even skin tone and target dark spots while remaining lightweight for daily layering.

This targeted ampoule blends brightening-focused actives in a fast-absorbing texture designed for use within a multi-step skincare routine. The formula centers on glutathione and tranexamic acid (TXA) supported by niacinamide and Vitamin Tree Water to address post-acne marks, patchy pigmentation, and overall lack of radiance without heavy or sticky residues. Packaged as a 10.7 g concentrate, it's intended for spot treatment or all-over tone refinement, suitable for sensitive skin types when introduced gradually.

How does this ampoule fit into my morning or evening routine?

Apply the ampoule after cleansing and lightweight toning, before heavier creams or oils. Use a few drops on targeted areas for spot care or spread thinly for broader tone refinement; follow with sunscreen in the morning.

• Layer under serum or moisturizer for added potency
• Use 1–2 drops for spot treatment, 3–4 drops for full-face application
• Always finish with SPF during daytime use to protect treated areas

What are the active ingredients and why are they included?

The key ingredients work together to support a more uniform-looking complexion. Glutathione is included for antioxidant support, tranexamic acid (TXA) targets uneven pigmentation mechanisms, and niacinamide helps improve visible clarity and texture.

• Glutathione — antioxidant support and brightening complement
• Tranexamic Acid (TXA) — targeted pigment management aid
• Niacinamide — clarity, barrier-friendly support, and smoothing
• Vitamin Tree Water — lightweight hydration and soothing base

Is this product suitable for sensitive skin and daily use?

The ampoule is formulated with sensitivity in mind and features a lightweight, fast-absorbing texture that layers easily. Start with patch testing and introduce gradually; discontinue if irritation occurs.

• Gentle texture designed for daily application
• Compatible with many routines — avoid combining with strong exfoliants initially
• Patch test recommended for highly reactive skin

How long until I may notice changes in uneven tone or dark spots?

Results vary by individual, skin concern, and consistency of use. Expect gradual improvements over weeks as part of a regular skincare regimen, not immediate or guaranteed transformations.

• Consistent nightly or twice-daily use improves chances of visible change
• Combine with sun protection to prevent recurrent darkening
• Maintain routine for several weeks to assess efficacy

Who is this for: numbuzin No.5 Glutathione TXA Dark Spot Ampoule suits people looking for a targeted, lightweight tone-care concentrate—those concerned with post-acne marks, patchy pigmentation, or general lack of evenness who prefer a layering-friendly Korean skincare product. It's appropriate for sensitive skin when introduced carefully and used alongside sun protection and a balanced routine.
