Cos De BAHA Tranexamic Acid Nacinamide Serum (TN)- 30ml

Cos De BAHA Tranexamic Acid Nacinamide Serum (TN)- 30ml is a Korean serum that targets stubborn dark spots and uneven skin tone using a combination of tranexamic acid and niacinamide. Designed for Bangladesh's intense year-round UV exposure, this formula works to fade post-inflammatory hyperpigmentation and melasma-related marks that tend to linger longer in our climate. The lightweight texture absorbs quickly without leaving residue, making it suitable for layering under moisturiser and sunscreen during the day or used alone at night.

How does Cos De BAHA Tranexamic Acid Nacinamide Serum (TN)- 30ml work

Cos De BAHA Tranexamic Acid Nacinamide Serum (TN)- 30ml is a brightening serum that helps reduce the appearance of dark spots and evens skin tone using tranexamic acid and niacinamide as its key actives.

Tranexamic acid works by inhibiting melanin production at the source, particularly helpful for those dealing with stubborn pigmentation triggered by inflammation or UV exposure. Niacinamide (also called nacinamide here) supports this process by strengthening the skin barrier, improving microcirculation, and helping regulate sebum production. Together, they create a dual-action approach: one targets pigment formation directly, while the other creates a more resilient canvas that better resists future discolouration.

Who benefits most

• Post-acne marks that take months to fade in Bangladesh's humid climate
• Melasma or sun-related darkening on forehead, upper lip, and cheeks
• Uneven skin tone from pollution exposure and oxidative stress
• Combination skin that needs hydration without heavy occlusion
• Oily or acne-prone skin that struggles with pigment retention
• Early signs of discolouration around the nose and chin area

Cos De BAHA Tranexamic Acid Nacinamide Serum (TN)- 30ml suits most skin types, though those with very sensitive skin should patch-test behind the ear for three days before full-face application.

How to use it

1. Cleanse thoroughly and pat skin completely dry before application
2. Dispense two to three drops onto fingertips and smooth evenly across face, avoiding the immediate eye area
3. Allow 60 seconds for absorption before following with moisturiser
4. Use twice daily — morning and evening — for consistent pigment regulation
5. Always finish morning routine with broad-spectrum SPF 30+; tranexamic acid increases photosensitivity under Bangladesh's strong UV

What to expect over time

Pigmentation treatments require patience, especially in climates where UV exposure resets progress daily. With Cos De BAHA Tranexamic Acid Nacinamide Serum (TN)- 30ml, initial brightening may appear within four to six weeks, though deeper marks often need three to four months of consistent use. The serum helps your skin maintain a more even tone and fade existing discolouration gradually, provided you pair it with diligent sun protection and avoid skipping applications.
