TIRTIR Niacinamide 20% Serum 30ml, High-Strength Pore-Refining & Brightening

TIRTIR Niacinamide 20% Serum is a concentrated 30ml treatment designed to refine pores, control oil, and brighten skin tone with 20% niacinamide plus complementary brightening and anti-aging actives.

This lightweight serum blends a high-strength 20% niacinamide base with supporting ingredients—Zinc PCA for sebum management, 2% alpha arbutin and glutathione for tone correction, and a stabilized retinol complex—for multi-targeted complexion improvement. Formulated for daily layering under moisturizer, it aims to address enlarged pores, uneven tone, and excess oil while remaining suitable for a variety of skin types when used as directed.

How does this serum help reduce the look of enlarged pores?

The high niacinamide concentration works to improve skin texture and the appearance of pore size by supporting surface renewal and balancing oil production. Zinc PCA further regulates sebum, helping pores appear less congested and visually smaller over time.

• 20% niacinamide to help refine texture and minimize the look of pores.
• Zinc PCA to control excess oil and reduce pore clogging.
• Light, fast-absorbing formula that layers under moisturizer without a heavy finish.

Can this serum brighten dark spots and even skin tone?

Yes—this formula combines alpha arbutin (2%) and glutathione to target pigmentation pathways and promote a more uniform appearance. Regular use can help fade post-acne marks and diffuse melanin-related discoloration when used alongside sun protection.

• 2% alpha arbutin to help inhibit melanin accumulation and reduce dark spots.
• Glutathione for antioxidant support and overall luminosity.
• Best results when paired with daily SPF to prevent new pigmentation.

Is this serum suitable for oily, combination, or sensitive skin?

The serum is formulated to address oily and combination concerns by regulating sebum and preventing pore congestion, while the niacinamide base supports barrier resilience to reduce irritation risk. Sensitive skin users should patch-test first and introduce the product gradually, especially because of the retinol component.

• Oil-controlling actives to balance shine without stripping hydration.
• Niacinamide helps strengthen the skin barrier to lower sensitivity reactions.
• Patch test recommended; introduce slowly if using other active ingredients.

How quickly can I expect to see improvements?

Some users may notice smoother texture and reduced oiliness within a couple of weeks, while fading of pigmentation and visible pore changes typically progress over several weeks with consistent use. Results vary by individual skin condition and concurrent skincare routine.

• Initial texture and oil-control effects often within 1–2 weeks.
• Pigment improvement and pore refinement usually take multiple weeks of consistent application.
• Combine with sunscreen and gentle exfoliation for optimal outcomes.

Who is this for: TIRTIR Niacinamide 20% Serum is built for those seeking a potent, multi-action serum to tackle enlarged pores, shine, and uneven tone—especially people with oily, combination, or resilient normal skin. If you’re introducing concentrated actives (high niacinamide, arbutin, retinol), start gradually, perform a patch test, and pair with daily SPF and a soothing moisturizer to support skin tolerance.
