TOSOWOONG Niacinamide 10% + Tranexamic Acid 4% Brightening Serum, 33ml — Hydrating, Lightweight

TOSOWOONG Niacinamide 10% + Tranexamic Acid 4% Serum is a lightweight Korean facial serum formulated to clarify skin tone, reduce the look of enlarged pores, and support a smoother, radiant complexion.

Designed as part of a targeted brightening and barrier-support routine, this 33 ml serum pairs a high-concentration 10% niacinamide with 4% tranexamic acid and 2% arbutin to address uneven tone and surface texture. Ceramide NP and hyaluronic acid help maintain hydration and soothe while the non-greasy, watery formula absorbs quickly. Fragrance-free and cruelty-free, it’s suitable for layering morning and night as part of most skincare regimens.

How does this serum improve the look of dull or uneven skin?

The concentrated blend targets visible surface discoloration and dullness while supporting a brighter-looking skin appearance. Niacinamide helps even tone and tranexamic acid works alongside arbutin to address spots and irregular pigmentation, creating a more uniform finish over time.

• 10% niacinamide for tone balancing and texture refinement
• 4% tranexamic acid for targeted brightening support
• 2% arbutin to help reduce the appearance of dark spots
• Visible radiance without heavy oils or silicones

Will the texture feel heavy or interfere with other products?

This serum has a thin, watery consistency that absorbs quickly and layers easily under moisturizers or sunscreen. Because it’s lightweight and free of added fragrance, it can be incorporated into both morning and evening routines with minimal pilling.

• Non-greasy, fast-absorbing watery texture
• Fragrance-free formula reduces irritation risk
• Works under hydrating creams and SPF without residue
• Suitable for layering 2–3 times for targeted areas

How does this serum support the skin barrier and hydration?

Hyaluronic acid provides immediate hydration by attracting moisture to the skin surface, while Ceramide NP helps strengthen and protect the skin’s natural barrier. Together they help maintain comfortable skin during daily use of active brightening ingredients.

• Hyaluronic acid for fast hydration and smoother feel
• Ceramide NP to support barrier resilience and reduce water loss
• Gentle formulation designed for daily application

How should I use this serum for best results?

Apply after cleansing and toner, dispensing an appropriate amount and spreading evenly across the face. For areas that need more attention, you can layer 2–3 applications; finish with moisturizer and sunscreen during the day.

• Use morning and night after toner and before moisturizer
• Layer 2–3 times on targeted spots if desired
• Follow with SPF in the daytime to protect results

Who is this for: TOSOWOONG Niacinamide 10% + Tranexamic Acid 4% Serum is made for anyone seeking a non-greasy, fragrance-free brightening step that also supports hydration and barrier health. It fits well into routines for combination, oily, normal, and many sensitive skin types that tolerate active brightening ingredients. Avoid if you have known sensitivities to niacinamide, tranexamic acid, or arbutin, and consult patch testing when introducing multiple actives.
