Naturium Tranexamic Acid 5% Serum, Jumbo 2 oz — Brightening with Kojic Acid & Niacinamide

Naturium Tranexamic Topical Acid 5% Jumbo is a concentrated 2 oz serum formulated to help even skin tone and support a calm, more radiant complexion.

This jumbo-size topical tranexamic acid serum combines a clinically minded strength of tranexamic acid with kojic acid, niacinamide and licorice root extract to target the appearance of uneven pigmentation and dullness while supporting the skin’s barrier. The formula is designed for gradual integration into a routine, suitable for a broad range of skin types, and packaged in a generous 2 oz bottle for longer use between purchases.

How should I add this serum into my morning and evening routine?

Start slowly to let your skin adjust: apply 1–2 pea-sized drops once daily for the first week, then work up to morning and evening as tolerated. Use it after cleansing and toning but before heavier creams and oils; always follow with sunscreen in the daytime.

• Apply on clean, dry skin; wait a minute before layering other products.
• Begin with single daily use and increase to AM + PM gradually.
• Pair with sunscreen each morning to protect results.

What results can I expect and how long will it take to notice changes?

Visible improvements to skin tone and brightness typically appear over several weeks of consistent use, though individual response times vary. The combination of tranexamic acid with brightening agents targets surface discoloration and can lead to a more uniform complexion when used regularly.

• First few weeks: skin may adjust; mild sensitivity can occur.
• 4–8 weeks: many users report smoother, more even-looking tone.
• Continued use: helps maintain tone and support barrier health.

Is this serum suitable for sensitive or acne-prone skin?

The formulation is created to be skin-compatible and is often suitable for sensitive or problematic skin, but a patch test is recommended. If irritation or redness appears, reduce frequency until comfort returns; consult a dermatologist for persistent reactions.

• Patch test before full-face application.
• Reduce frequency if mild irritation occurs; stop if severe.
• Dermatologist-tested and free from parabens and gluten.

What key ingredients are in the formula and what do they do?

Tranexamic acid at 5% is the core active for addressing discoloration. Kojic acid and niacinamide support brightening and texture, while licorice root adds a calming botanical element. The blend is balanced at a skin-appropriate pH and packaged in a larger size for longer use.

• Tranexamic Acid 5% — targets uneven pigmentation appearance.
• Kojic Acid — helps brighten and refine the surface tone.
• Niacinamide — supports even tone and barrier resilience.
• Licorice Root Extract — provides soothing botanical support.

Who is this for? This 2 oz Naturium Tranexamic Topical Acid serum is aimed at people seeking a potent, budget-friendly brightening serum who want to reduce the look of uneven skin tone, discoloration, or dullness. It suits those who prefer evidence-backed actives in a fragrance-minimal formula and anyone who wants a larger size to extend their routine between purchases. If you have very reactive skin or are pregnant, consult a skincare professional before adding concentrated actives.
