The “Glass Skin” Miracle: Fade Spots & Glow Like Never Before!
Experience the pinnacle of Korean clinical skincare with the TOSOWOONG Niacinamide 10% + Tranexamic Acid 4% Serum. This high-performance treatment is not just another brightening serum; it’s a potent cocktail of the industry’s most proven molecules, expertly formulated to erase dark spots, smooth texture, and deliver that coveted, translucent “glass skin” glow.
Why It’s a Game-Changer:
Most serums use minimal actives, but TOSOWOONG goes all out. By combining a massive 10% Niacinamide with 4% Tranexamic Acid (TXA) and 2% Arbutin, this triple-threat formula attacks hyperpigmentation from every angle. It blocks melanin production, breaks up existing pigment, and prevents new spots from forming—all while being gentle enough for daily use.
Key Ingredients & Benefits:
-
10% Niacinamide: A clinical-strength dose that tightens enlarged pores, controls excess oil, and strengthens the skin barrier.
-
4% Tranexamic Acid: The gold standard for treating melasma and stubborn post-acne marks (PIH) that won’t go away.
-
2% Arbutin: A safe, natural brightener that evens out skin tone for a radiant finish.
-
Hyaluronic Acid & Ceramide NP: Provides deep, non-sticky hydration to plump up fine lines and keep your skin dewy.
-
Natural Color: Its beautiful soft pink hue comes naturally from Cyanocobalamin (Vitamin B12)—no artificial dyes here!
How to Use:
Apply 2–3 drops to clean, toned skin morning and night. Gently pat until absorbed. The lightweight texture sinks in instantly, leaving no greasy residue. Pro tip: Always follow with sunscreen in the morning to protect your brightened skin!
Unlock Your Radiance:
Say goodbye to dull, uneven skin and hello to a complexion so clear, it looks like glass.
