TirTir Niacinamide 20% Serum 30ml | Korean Shop BD

What is the TirTir Niacinamide 20% Serum? It is a high-performance Korean brightening serum that delivers one of the highest available concentrations of Niacinamide — 20% (200,000ppm) — to visibly reduce hyperpigmentation, refine enlarged pores, and regulate excess oil production with daily use. Paired with 2% Alpha Arbutin and Glutathione, it targets melanin at multiple pathways for faster, more visible tone correction.

Beyond brightening, the formula incorporates Retinol 500IU for anti-aging care, Zinc PCA for sebum balance, and three forms of Hyaluronic Acid for deep, layered hydration. It is free from parabens, sulfates, and synthetic fragrance — dermatologically tested and suitable for all skin types, including sensitive skin.

Key Benefits of TirTir Niacinamide 20% Serum

• 20% Niacinamide (200,000ppm) visibly fades blemishes, tightens enlarged pores, and evens uneven skin tone with daily use
• 2% Alpha Arbutin and Glutathione inhibit melanin production from multiple pathways for faster brightening and dark spot reduction
• Zinc PCA regulates sebum and controls surface oil without stripping moisture or disrupting the skin barrier
• Retinol 500IU supports collagen synthesis, reduces the appearance of fine lines, and improves overall skin texture
• Triple Hyaluronic Acid complex — standard, hydrolyzed, and sodium forms — delivers multi-depth hydration and strengthens skin elasticity
• Paraben-free, fragrance-free, and dermatologically tested — suitable for sensitive, oily, and acne-prone skin

Skin Types and Concerns

• Oily and acne-prone skin: Zinc PCA and 20% Niacinamide together regulate sebum production, reduce surface shine, and minimize the look of clogged and enlarged pores
• Hyperpigmentation and dark spots: Alpha Arbutin and Glutathione work alongside Niacinamide to interrupt melanin synthesis from multiple pathways for more visible brightening over time
• Aging and loss of elasticity: Retinol 500IU stimulates cell turnover and supports collagen production, visibly softening fine lines and improving overall skin firmness
• Dehydrated and compromised skin barrier: Triple Hyaluronic Acid complex replenishes moisture at different skin depths and helps rebuild resilience with consistent daily use

Why You Should Have TirTir Niacinamide 20% Serum

• Anyone dealing with enlarged pores and excess oil in Bangladesh's humid climate who wants one serum to manage both
• People looking to add Retinol to their routine without a dedicated retinol product — this serum covers both brightening and anti-aging in one step
• Those who have tried lower-concentration Niacinamide serums (2–5%) without visible improvement and need a significant upgrade
• Anyone building a results-driven, minimal routine around one hardworking serum that covers tone, texture, pores, and hydration
