medicube TXA Niacinamide Glow Serum 1.01 fl.oz — 5% Tranexamic Acid, 10% Niacinamide for Post-Spot Brightening and Hydration

medicube TXA+Niacinamide 15% Glow Facial Serum is a lightweight daily treatment that blends 5% tranexamic acid, 10% niacinamide and 2% arbutin to target post-spot discoloration, uneven tone, and surface texture while delivering multi-layer hydration.

This Korean-formulated serum focuses on recovery after blemishes and on refining overall skin clarity without heavy fragrance or harsh irritation. The formula combines high-potency actives with skin-calming ingredients and ten-layer hyaluronic complexes to hydrate, soften texture, and support a more even complexion. It's designed for regular use in morning or evening routines and aims to improve visible radiance quickly while staying gentle enough for sensitive skin types when used as directed.

How does this serum help reduce post-spot discoloration?

The serum uses 5% tranexamic acid (TXA) alongside arbutin and 10% niacinamide to target pigment formation pathways and support a more uniform skin tone. These actives work together to help fade dark marks and prevent new discoloration from forming when combined with sun protection.

• 5% tranexamic acid for targeted after-spot care.
• 2% arbutin to inhibit melanin synthesis.
• 10% niacinamide for brightening and barrier support.
• Fragrance-free to reduce irritation risk during spot care.

Will this serum improve skin texture and hydration?

Yes—medicube layered hyaluronic acids plus soothing humectants and panthenol work to smooth roughness while delivering lasting moisture. The result is softer, plumper skin surface with improved touch and appearance over weeks of consistent use.

• 10-layer hyaluronic acid complex for multi-depth hydration.
• Panthenol and betaine to calm and support barrier repair.
• Light, non-greasy texture suitable under makeup or SPF.
• Improves smoothness clinically within one week for many users.

Is this safe for daily use on sensitive or acne-prone skin?

The formula is developed to be low-irritation and non-fragranced, with calming Coral Moss extract and panthenol to soothe reactive skin. Patch testing is recommended for very reactive individuals; incorporate gradually if you use other active ingredients like retinoids or strong acids.

• Fragrance-free, low-irritation base for daily layering.
• Calming extracts help minimize redness and sensitivity.
• Compatible with most serums, but layer cautiously with potent actives.
• Use SPF during daytime to protect treated areas from darkening.

How quickly can you expect visible results?

Clinical testing indicated measurable radiance increases after a single application and texture improvements within about one week for many participants. Individual timelines vary depending on skin type, severity of discoloration, and overall routine consistency.

• Noticeable radiance uplift reported after the first use in trials.
• Texture smoother in approximately one week for some users.
• Best results seen with regular use and daily sun protection.
• Consistency and complementary skincare accelerate outcomes.

Who is this for: medicube TXA+Niacinamide 15% Glow Serum suits anyone seeking targeted after-spot care combined with hydration and brightening—especially those wanting a high-strength tranexamic acid blend without fragrance. Ideal for people with uneven tone, post-inflammatory marks, or textured skin who prefer a lightweight, daily-friendly serum that layers easily under moisturizers and SPF.
