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 out skin tone and support a calmer, more radiant-looking complexion.

This jumbo-size treatment combines tranexamic acid at a targeted 5% concentration with kojic acid, niacinamide and licorice root extract to address the appearance of uneven pigmentation and texture. Designed for daily use in both AM and PM routines, the formula is pH-appropriate, vegan, cruelty-free and free from parabens and gluten. While effective for a variety of skin types, those with sensitivity should introduce it gradually and perform a patch test first.

How will this serum fit into my morning and evening routine?

Use 1–2 pea-sized drops after cleansing and before heavier creams. Start with once daily or every other day, increasing to twice daily as tolerated. Always follow with SPF in the morning because targeted brightening actives can increase sun sensitivity.

• Apply to clean, dry skin—press in gently until absorbed
• Layer niacinamide serums and moisturizers over it for added barrier support
• Finish AM with broad-spectrum sunscreen SPF 30+

What results can I expect and how quickly?

Visible changes in skin tone and clarity typically develop over weeks as the active ingredients work on pigmentation and texture. Consistent use, sun protection and patience are key; tranexamic acid and kojic acid act gradually rather than delivering instant transformation.

• Initial skin comfort or mild redness may resolve within days to weeks
• Noticeable improvements often appear within 4–12 weeks with regular use
• Maintain results by continuing routine plus daily sun protection

Is this suitable for sensitive or problem-prone skin?

The formula is crafted to be skin-compatible and dermatologist tested, but active brightening agents can still provoke sensitivity. Introduce the serum slowly, monitor your skin’s response, and reduce frequency if irritation occurs. Patch testing is recommended before applying broadly.

• Start with every-other-day application, then move to daily if comfortable
• Use minimal amounts—1–2 pea-sized drops—avoiding broken or inflamed skin
• Combine with calming, hydrating products like ceramide or barrier-support moisturizers

Which key ingredients are in the formula and why do they matter?

Naturium’s serum blends tranexamic acid at 5% with kojic acid, niacinamide, and licorice root extract to target uneven tone while supporting surface calm and barrier health. Each ingredient contributes to a balanced approach: tranexamic helps regulate the look of discoloration, kojic assists in brightening, niacinamide reinforces barrier function, and licorice soothes.

• Tranexamic acid 5%: targeted support for pigmentation appearance
• Kojic acid: complementary brightening agent to even skin tone
• Niacinamide: helps strengthen barrier and improve texture
• Licorice root extract: offers calming benefits and antioxidant support

Who this is for: This jumbo-size serum suits anyone wanting a targeted, value-conscious approach to improving the look of uneven tone and texture—particularly those who prefer scientifically focused formulations without fragrances or parabens. It’s suitable for most skin types, including sensitive and acne-prone skin when used cautiously; those with active irritation, open wounds, or known ingredient sensitivities should consult a skin professional or pause use.
