TOSOWOONG Niacinamide + Tranexamic Acid Brightening Serum, 33ml — 10% Niacinamide, Lightweight TXA Treatment

TOSOWOONG Niacinamide 10% + Tranexamic Acid 4% Serum is a lightweight Korean facial serum formulated to brighten, clarify, and hydrate skin for a smoother, more even-looking complexion.

This concentrated 33 ml serum combines clinically popular actives—10% niacinamide, 4% tranexamic acid (TXA) and 2% arbutin—with hyaluronic acid and ceramide NP to target dullness, uneven tone, and visible pores while supporting the skin barrier. Its water-light texture absorbs quickly and the naturally tinted pink color reflects botanical-derived pigments rather than synthetic dyes. Fragrance-free and cruelty-free, the formula is designed for daily layering in both AM and PM routines.

How will this serum affect my skin's tone and brightness?

The serum blends niacinamide, tranexamic acid and arbutin to address uneven pigmentation and surface dullness. Regular use can help reveal a more uniform appearance and a luminous surface without heavy oils or creams.

• 10% niacinamide for visibly smoother texture and reduced look of pores.
• 4% tranexamic acid to target discoloration-prone areas and promote even tone.
• 2% arbutin as a supplemental brightening ingredient for overall radiance.

Is the texture suitable for layering with other skincare products?

Yes — the serum is formulated as a lightweight, fast-absorbing watery gel that layers well under moisturizers and sunscreens. It won’t leave a greasy residue, making it easy to include in multi-step Korean or minimalist routines.

• Non-greasy, quick-absorbing feel that mixes well with hydrating toners and creams.
• Hyaluronic acid delivers surface hydration to improve subsequent product absorption.
• Ceramide NP helps maintain the skin barrier when using active ingredients daily.

Can people with sensitive or reactive skin use this serum?

The formula is fragrance-free and excludes 26 common allergenic fragrance substances, which reduces irritation risk for many users. However, because it contains potent actives, patch testing is recommended if you have very reactive skin.

• Fragrance-free formulation to lower sensitization risk.
• Ceramide NP and hyaluronic acid to soothe and support the barrier.
• Start with a small amount and build frequency; discontinue if persistent irritation occurs.

How should I incorporate it into my daily routine for best results?

Apply after cleansing and toning, both morning and night. Use an appropriate amount and press gently into skin; for targeted areas, you can layer 2–3 times as needed. Always follow daytime use with sunscreen to protect results.

• Step 1: Cleanse and tone to prep skin.
• Step 2: Dispense serum, apply evenly, or layer on target zones.
• Step 3: Seal with moisturizer; use SPF during the day.

Who is this for? The TOSOWOONG Niacinamide 10% + Tranexamic Acid 4% Serum suits anyone seeking a lightweight, effective brightening step—especially those with combination, oily, or normal skin types looking to refine pores, improve uneven tone, and add hydration without a heavy finish. It’s a practical option for people building a Korean-inspired regimen, those who prefer fragrance-free formulas, and users wanting to combine barrier-supporting ceramides and hyaluronic acid with targeted actives. If you have highly sensitive or ingredient-reactive skin, do a patch test first and introduce slowly.
