numbuzin No.5 Glutathione TXA Dark Spot Ampoule — 10.7g lightweight serum with tranexamic acid & niacinamide for even tone

numbuzin No.5 Glutathione TXA Dark Spot Ampoule is a lightweight, targeted serum designed to visibly even skin tone and address dark spots with a blend of glutathione, tranexamic acid, and niacinamide.

This concentrated ampoule from numbuzin focuses on reducing the appearance of discoloration, post-acne marks, and uneven tone while fitting smoothly into daily skincare routines. The formula combines antioxidant support and tone-regulating actives in a fast-absorbing texture so you can layer it under moisturizers and sunscreen without heaviness. Designed with sensitivity in mind, it aims to deliver targeted care for brighter-looking skin over time when used consistently.

How does this ampoule target dark spots and uneven tone?

The serum pairs glutathione with tranexamic acid (TXA) and niacinamide to address multiple steps in skin tone irregularities. Glutathione provides antioxidant support while TXA helps regulate processes that contribute to visible discoloration; niacinamide promotes clarity and surface texture improvement. Together they work to refine the appearance of marks and create a more uniform complexion with regular use.

• Glutathione for antioxidant support to help refresh skin appearance
• Tranexamic acid to help regulate visible spot-related pathways
• Niacinamide to improve surface clarity and skin texture
• Lightweight vehicle for even application and quick absorption

Will this ampoule suit sensitive or daily-use routines?

numbuzin No.5 is formulated to be gentle enough for daily layering and compatible with many routine steps. Its fine, non-greasy texture absorbs quickly so it won’t interfere with serums, creams, or sunscreen. Nonetheless, patch testing is recommended if you have highly reactive skin or are using other active treatments.

• Fast-absorbing, non-sticky texture for morning and evening use
• Compatible with moisturizers and sunscreens when layered properly
• Designed to be gentle, suitable for a range of skin sensitivities
• Patch test first if combining with potent exfoliants or retinoids

How should I apply the ampoule for best results?

Apply a small amount to cleansed skin after toner and before moisturizer to target areas with dark spots or uneven tone. Gently press the formula into the skin until fully absorbed; follow with a hydrating cream and daytime SPF. Consistent use is key to observing improved balance in overall skin tone.

• Use 1–2 drops on targeted areas after cleansing and toning
• Pat gently until absorbed, then follow with moisturizer
• Apply sunscreen during the day to protect results
• Use regularly to support gradual improvement in appearance

What kind of texture and finish can I expect?

The ampoule offers a fine, almost serum-like texture that sinks in quickly without leaving a sticky film. It layers well under heavier creams or makeup and leaves a smooth surface that helps subsequent products apply evenly. The finish is lightweight and breathable, suited to both oily and normal skin types.

• Fine, watery-gel consistency for quick penetration
• Non-greasy finish that won’t clog pores
• Plays well with other skincare and makeup products
• Designed for daily use without residue

Who is this for? numbuzin No.5 Glutathione TXA Dark Spot Ampoule is aimed at anyone seeking a targeted, gentle solution for the look of post-acne marks, sun spots, and uneven skin tone. It suits users who prefer lightweight, fast-absorbing treatments and those building a multi-step Korean skincare routine that prioritizes clarity and balance. If you need a focused ampoule to layer under moisturizer and SPF while supporting a brighter-looking complexion, this product offers a concentrated option to add into your regimen.
