TIRTIR Niacinamide 20% Serum 30ml — Pore-Refining, Oil-Control Formula with Retinol & Alpha Arbutin

TIRTIR Niacinamide 20% Serum is a high-strength facial serum formulated to refine pores, regulate oil, and brighten skin tone with targeted actives including niacinamide, zinc PCA, alpha arbutin, glutathione and retinol.

This lightweight 30ml serum concentrates multiple actives in a single routine step to address enlarged pores, uneven pigmentation and excess sebum while supporting skin texture. The formula combines a 20% niacinamide base with oil-regulating zinc PCA, clarifying brighteners and a low-dose retinol complex designed for pore care. It is intended for twice-daily or nightly use depending on tolerance and layers well under moisturizers or SPF.

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

The high niacinamide concentration works to support smoother-looking skin surface and help minimize pore appearance by improving overall texture and balancing sebum. Retinol 500 contributes to cellular turnover and the product’s multi-step pore care approach supports reductions in pore depth and volume over consistent use.

• 20% niacinamide to improve surface texture and pore clarity
• Retinol 500 assists with turnover and pore remodeling
• Zinc PCA controls sebum that can enlarge pore appearance
• Formulated for layered use with moisturizers and SPF

Will this serum help with oil control without drying my skin?

Yes — the serum balances oil production while maintaining hydration. Zinc PCA is included to modulate sebum flow and help prevent pore-clogging, while the overall formula avoids heavy alcohols that strip moisture, so skin retains a healthy, non-greasy finish.

• Zinc PCA for targeted oil regulation
• Hydration-supportive base to prevent tightness
• Suitable for combination to oily skin, and formulated to reduce pore blockages

How does it address discoloration and dullness?

The serum blends 2% alpha arbutin with glutathione to target uneven pigmentation and support a brighter look. These brightening actives help reduce the prominence of dark spots while niacinamide contributes to an evened tone and improved radiance over time.

• 2% alpha arbutin to inhibit excess melanin appearance
• Glutathione for oxidation support and brighter-looking skin
• Niacinamide enhances overall luminosity and evens tone

How should I introduce this serum into my routine safely?

Start slowly: apply a pea-sized amount once every other night for the first two weeks, then increase frequency as tolerated. Use sunscreen each morning, avoid combining with other strong exfoliants initially, and layer under your regular moisturizer; adjust usage if you experience irritation.

• Begin with alternate-night application, then increase as tolerated
• Morning sunscreen is essential when using retinol-containing products
• Do not mix simultaneously with high-strength AHAs/BHAs without guidance
• Compatible with most hydrating creams and oil-free moisturizers

Who is this for: TIRTIR Niacinamide 20% Serum is designed for people wanting a concentrated, multi-action treatment to refine pore appearance, manage excess oil and improve skin brightness. It suits oily, combination and many sensitive-prone skin types that can tolerate active ingredients when introduced carefully. If you have very reactive skin or are using prescription retinoids, consult a skincare professional before adding this product.
