TOSOWOONG Niacinamide + Tranexamic Acid Serum 33ml — 10% Niacinamide, 4% TXA for Brightening & Hydration

TOSOWOONG Niacinamide 10% + Tranexamic Acid 4% Serum is a lightweight daily facial serum formulated to brighten, refine pores, and hydrate for a clear, glass-skin finish.

This 33ml Korean skincare serum blends potent actives—10% niacinamide, 4% tranexamic acid (TXA), and 2% arbutin—alongside hyaluronic acid and Ceramide NP to help improve skin texture and hydration without heavy residue. The formula is fragrance-free, cruelty-free, and designed for regular use in morning and evening routines. Its subtle natural pink hue comes from botanical components, not artificial dyes, and the watery texture absorbs quickly to layer well under moisturizers and sunscreens.

How will this serum affect uneven tone and dark spots?

The combination of niacinamide, tranexamic acid and arbutin targets areas of uneven pigmentation and helps fade discoloration over time when used consistently. These ingredients work through different pathways to address dullness and hyperpigmentation while being suitable for layering with other actives.

• Niacinamide 10% supports skin-brightening and reduces the look of blotchiness.
• Tranexamic Acid 4% helps calm inflammation-related pigmentation.
• Arbutin 2% contributes to lightening spot-prone areas safely.
• Daily application yields gradual, noticeable evening of tone.

Is this serum appropriate for sensitive or barrier-compromised skin?

Formulated without added fragrance and with Ceramide NP plus hyaluronic acid, the serum aims to hydrate and help protect the skin barrier while delivering active benefits. It is presented as gentle for everyday use, but patch testing is recommended for very reactive skin.

• Fragrance-free formula reduces risk of irritation from scents.
• Ceramide NP supports the lipid barrier and skin resilience.
• Hyaluronic acid supplies lightweight hydration without greasiness.
• Start with once-daily use if you have sensitive skin, then increase.

How should I incorporate this into my skincare routine?

Use the serum after cleansing and toning, then follow with moisturizer and sunscreen in the morning. A thin, watery texture allows easy layering; for target areas you may apply two to three light layers as needed.

• Step 1: Cleanse and apply toner or essence.
• Step 2: Dispense a few drops of serum and spread evenly.
• Step 3: Follow with moisturizer; always use SPF in daytime.
• Step 4: For concerns, layer 2–3 thin applications on spots.

What results can I expect and how long will they take?

Visible improvements in hydration and surface texture can appear quickly, while reduction in pigmentation and pore appearance may take several weeks of consistent use. Individual results vary depending on skin type and concurrent skincare steps, especially sun protection.

• Immediate: lighter, non-greasy hydration and smoother feel.
• 4–8 weeks: gradual evening of skin tone and reduced dullness.
• Continued use: supports a clearer, more refined complexion over time.
• Pair with daily SPF for best pigmentation results.

Who is this for? TOSOWOONG Niacinamide 10% + Tranexamic Acid 4% Serum is aimed at anyone seeking a compact, active-driven serum to address dullness, enlarged pores and uneven tone while maintaining hydration. It suits all skin types that tolerate niacinamide and TXA, including those building a targeted brightening routine or adding a hydrating step to achieve a glass-skin finish. If you have particularly reactive skin, perform a patch test and introduce it gradually alongside sun protection for optimal results.
