TIRTIR Niacinamide 20% Serum 30ml — Pore-Smoothing, Oil-Control & Brightening

TIRTIR Niacinamide 20% Serum is a concentrated daily serum formulated to even skin tone, refine pores, control oil, and boost radiance with a 30ml dropper bottle.

Combining a high-strength 20% niacinamide base with supportive actives like Zinc PCA, 2% Alpha Arbutin, Glutathione and Retinol 500, this lightweight serum targets multiple skin concerns at once: uneven pigmentation, excess shine, and visible pore texture. The formula is designed for routine use to help improve surface appearance and skin clarity while maintaining hydration balance.

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

The concentrated niacinamide works to smooth the appearance of pores while Zinc PCA helps regulate sebum production that can make pores more noticeable. Over several weeks, users commonly see a more refined texture and reduced pore prominence.

• 20% niacinamide for pore-smoothing support
• Zinc PCA to help balance oil and reduce pore-clogging
• Lightweight, fast-absorbing texture that won’t feel heavy

Will this serum improve dullness and uneven pigmentation?

The brightening blend pairs 2% Alpha Arbutin with Glutathione to help even skin tone and fade the look of dark spots over time. Regular use alongside sun protection supports a clearer, more luminous complexion.

• Alpha Arbutin targets visible hyperpigmentation
• Glutathione supports overall skin brightness
• Niacinamide aids in reducing discoloration appearance

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

This serum is formulated to address multiple skin types, particularly oily and combination skin, by balancing moisture and excess sebum. The formula’s hydrating and sebum-controlling actives aim to maintain skin comfort while minimizing irritation risk when used as directed.

• Non-greasy formula that absorbs quickly
• Zinc PCA reduces excess oil without over-drying
• Suitable for sensitive skin when patch-tested first

How should I layer this serum into my skincare routine?

Apply the serum after cleansing and toning, before heavier creams and oils. Start with a few drops, use once daily at night or as tolerated, and follow with sunscreen during daytime to protect treated skin.

• Apply to clean, dry skin—morning or evening
• Follow with moisturizer; use SPF in daytime
• Introduce gradually if you’re new to high-strength actives

Who is this for: TIRTIR Niacinamide 20% Serum is best suited for people seeking multi-targeted skin improvement—those with visible pores, occasional breakouts or oily-prone complexions, and anyone looking to brighten uneven tone. If you use retinoids or have very reactive skin, introduce the product slowly and consult a dermatologist if unsure.
