TOSOWOONG Niacinamide 15% Face Serum — Dark Spot Corrector, Zinc PCA for Oil Control & Refined Pores

TOSOWOONG Niacinamide 15% Face Serum is a concentrated daily treatment designed to even skin tone, reduce the look of enlarged pores, and support a smoother, glass-skin finish.

This lightweight serum combines a high 15% niacinamide concentration with Zinc PCA to help control excess oil, refine skin texture, and address visible dark spots and uneven tone. Formulated for daily use, it sits well under moisturizers and makeup, and is suitable for oily, combination, and congested skin types when introduced gradually. Follow recommended usage and patch testing to ensure compatibility with your routine.

How will this serum affect oily or pore-prone skin?

The formula targets factors that commonly make pores look larger: excess sebum and uneven texture. Niacinamide helps regulate oil production while Zinc PCA supports sebum balance, so skin looks smoother and less congested over time. Results depend on consistent use and an overall skincare routine.

• Controls shine and reduces visible oiliness
• Helps refine and visibly tighten pore appearance
• Lightweight, non-greasy texture suitable under makeup

Can this reduce dark spots and uneven tone?

The serum's high niacinamide content supports a more uniform-looking complexion by helping to modulate pigmentation processes and improve skin barrier function. Regular application can make age spots and post-acne marks less noticeable, especially when combined with sun protection. It is not an immediate removal treatment—consistent use yields gradual improvement.

• Targets discoloration with daily application
• Works best alongside SPF to prevent new darkening
• Suitable for use under makeup or layered with other treatments

How should I incorporate this into my routine safely?

Start with 2–3 drops once daily, then increase to twice daily as tolerated. Apply to clean, dry skin before heavier serums or creams. Because it is a high-concentration active, a patch test is recommended and you should avoid direct eye contact.

• Patch test on body; wait 24 hours before full-face use
• Apply 2–3 drops morning or evening; use SPF during the day
• Can be used under the eyes cautiously, avoiding lashes

Will it cause irritation or interact with other actives?

Some people sensitive to strong actives may experience temporary redness or tingling when first introduced. Pairing with gentle hydrators and avoiding simultaneous use with high-strength acids or retinoids can reduce irritation risk. If irritation occurs, discontinue and consult a healthcare professional.

• May cause temporary sensitivity during adjustment
• Use with caution alongside strong exfoliants or prescription actives
• Reduce frequency or pause use if persistent irritation appears
