Naturium Tranexamic Acid Serum 5% – 1 oz Brightening Lightweight Formula with Kojic Acid & Niacinamide

Naturium Tranexamic Topical Acid 5% is a targeted brightening serum formulated to help even skin tone and support a calmer, smoother complexion.

This lightweight 1 oz serum combines 5% tranexamic acid with kojic acid, niacinamide and licorice root extract to address visible unevenness and discoloration while maintaining skin barrier compatibility. The formula emphasizes gentle potency appropriate for gradual introduction into a routine and is made without parabens, gluten or animal testing. Designed for daily use AM and PM (with patch testing and sun protection advised), it supports a more luminous appearance without heavy fragrances.

How does this serum help reduce the appearance of uneven tone?

The active ingredient, tranexamic acid at a 5% concentration, works alongside kojic acid and licoramide-supporting ingredients to target areas of visible discoloration and improve overall tone appearance. Niacinamide calms and helps refine texture while licorice root provides botanical brightening support. Together, these components aim to create a more uniform look without overly stripping or irritating the skin.

• 5% tranexamic acid for targeted tone support
• Kojic acid to complement brightening activity
• Niacinamide to soothe and refine skin texture
• Licorice root extract for botanical balancing benefits

How should I introduce it into my skincare routine for sensitive skin?

Start slowly: apply 1–2 pea-sized drops once daily, then increase to AM and PM as tolerance builds. If you notice mild redness or sensitivity, reduce frequency until the skin adjusts. Always patch test a small area before full-face application and pair with daily sunscreen during daytime use.

• Begin with 1–2 drops once daily, then increase gradually
• Patch test before full application
• Use SPF during daytime to protect new skin tone improvements
• Adjust frequency if irritation appears

Can I layer this with other active ingredients like retinol or vitamin C?

This serum can be incorporated with other actives, but spacing them out reduces the chance of irritation. Use tranexamic acid in a separate part of your routine from potent exfoliants or strong retinoids, or alternate nights. If combining with vitamin C, monitor tolerance and consider using vitamin C in the morning and tranexamic acid at night or vice versa based on your skin’s response.

• Alternate nights with retinoids to minimize sensitivity
• Space strong acids and exfoliants apart from application
• Monitor skin response and reduce frequency if needed
• Consult a dermatologist for complex active combinations

What results and timeline can I realistically expect?

Individual responses vary, but many users notice gradual improvements in tone and texture over several weeks of consistent use. Because this product focuses on visible tone and barrier support rather than immediate peeling, changes are typically subtle and cumulative. Continued, regular application alongside sunscreen helps maintain and enhance results.

• Visible improvements often appear over multiple weeks
• Consistent use plus sun protection yields best outcomes
• Gentle formula supports barrier health during treatment

Who is this for: This serum is intended for people seeking a measured, scientifically-minded approach to evening skin tone without heavy irritation — including those with sensitive or reactive skin types who want to introduce effective actives gradually. It suits anyone looking for a fragrance-minimal, dermatologist-tested option to pair with a broader skincare routine, provided they patch test and use daytime sun protection.
