medicube TXA+Niacinamide Glow Facial Serum 1.01 fl.oz — 5% Tranexamic Acid, 10% Niacinamide

medicube TXA+Niacinamide 15% Glow Facial Serum is a high-potency, daily Korean serum combining 5% tranexamic acid with 10% niacinamide and supportive hydrators to target post-spot discoloration, uneven tone, and texture for a brighter, smoother complexion.

This lightweight, fragrance-free formula is designed as an all-in-one glow layer to use after spot care or as part of your everyday routine. The serum blends tranexamic acid at medicube's maximum application rate with niacinamide, arbutin, multi-weight hyaluronic acids, panthenol, and coral moss extract to hydrate, calm, and refine skin without heavy residues. Clinical testing by Custis Life Science Research Center reports measurable improvements in radiance and texture, though individual results vary.

How does this serum help reduce post-spot discoloration?

The core active, tranexamic acid (5%), works alongside arbutin and niacinamide to support a more even skin tone and help minimize the appearance of dark spots that remain after blemishes heal. Regular, gentle application targets pigmentation pathways while avoiding harsh exfoliation.

• 5% tranexamic acid for targeted after-spot care
• 2% arbutin to inhibit hyperpigmentation processes
• 10% niacinamide to brighten and strengthen the skin barrier
• Fragrance-free, low-irritation base suitable for daily layering

Will this serum hydrate and improve skin texture?

Yes — the formula combines a 10-layer hyaluronic acid system with panthenol and betaine to deliver multi-depth hydration that plumps fine texture and smooths roughness. The lightweight texture absorbs quickly, helping makeup and other treatments sit evenly.

• Multi-weight hyaluronic acids for surface and deeper hydration
• Panthenol and betaine to soothe and retain moisture
• Clinical texture improvement observed after one week in trials
• Non-greasy finish for daytime use under sunscreen

Is this serum safe for daily use and sensitive skin?

The formula is designed for low irritation: it’s fragrance-free and includes calming coral moss extract plus panthenol. While the overall blend is gentle, tranexamic acid at therapeutic levels can still cause sensitivity for some users, so introduce it gradually and patch test first.

• Fragrance-free, lightweight daily texture
• Soothing ingredients to reduce redness and irritation
• Start with alternate-day application if you have reactive skin
• Patch test behind the ear or inner forearm before full-face use

How should this serum be layered into a routine?

Apply after cleansing and toning, before heavier creams or oils. Because it’s designed to work with other actives, you can use it morning and/or night, but always follow with sunscreen during daytime to protect treated areas.

• Cleanse and tone, then dispense 2–3 drops onto fingertips
• Pat gently over target areas or across the face until absorbed
• Follow with moisturizer and daily SPF in the morning
• For combination with strong exfoliants, space out use to minimize irritation

Who this is for: medicube TXA+Niacinamide 15% Glow Facial Serum suits anyone aiming to reduce lingering post-spot marks, even out skin tone, and add lightweight hydration without heavy oils or fragrance. It’s especially useful for those who want a clinically backed, high-strength tranexamic acid option to incorporate into a daily Korean skincare routine — ideal for normal, combination, and resilient dry skin types. If you have highly reactive skin or are using other potent actives, introduce the serum gradually and consult a dermatologist for personalized guidance.
