Paula's Choice Clinical 20% Niacinamide Face Serum — 0.67 oz Fragrance-Free, Pore-Tightening & Brightening

Paula's Choice CLINICAL 20% Niacinamide Serum is a high-strength vitamin B3 treatment designed to visibly tighten enlarged pores and reduce discoloration without fragrance.

This concentrated face serum blends 20% niacinamide with brightening botanicals to refine pore appearance, smooth rough texture, and even skin tone. Formulated fragrance-free and backed by science, it’s intended for use as a targeted treatment step in an anti-aging or resurfacing routine. The lightweight liquid absorbs quickly and layers under moisturizers and sunscreens.

How does this serum reduce the look of large pores?

The serum uses a 20% concentration of niacinamide, which supports healthier pore function and can tighten the skin’s surface for a refined appearance. Regular use helps reduce the stretched, sagging look associated with age and sun damage, improving overall texture.

• High 20% niacinamide concentration for visible pore tightening
• Targets weakened pore walls to reduce stretched appearance
• Lightweight formula absorbs quickly without clogging

Will this help with uneven skin tone and discoloration?

Yes — the serum combines niacinamide with brightening agents such as licorice root to address blotchy tone and hyperpigmentation. It helps fade discoloration over time while supporting a more luminous, even complexion when used consistently.

• Licorice root extract brightens and reduces visible dark spots
• Niacinamide helps regulate pigment and reduces blotchiness
• Designed for consistent, gradual improvement with continued use

Can this product smooth hard, clogged bumps and rough texture?

The formula targets congested pores and hard, bump-like texture that creates an orange-peel appearance. By improving pore function and surface clarity, it helps reveal smoother, clearer skin without harsh physical exfoliation.

• Helps soften and clear hard, trapped sebum and debris
• Improves skin surface for reduced orange-peel texture
• Suitable as part of a resurfacing routine alongside exfoliants

How should I use this serum in my skincare routine?

Apply a few drops to clean, dry skin once or twice daily, depending on tolerance, then follow with moisturizer and sunscreen in the morning. Start slowly if your skin is sensitive: alternate nights or mix a drop with your serum to build tolerance.

• Use after cleansing and toning, before heavier creams
• Morning application requires sunscreen to protect results
• Begin with small amounts or reduced frequency for sensitive skin

Who is this for: Paula's Choice CLINICAL 20% Niacinamide Serum is formulated for people noticing enlarged pores, uneven tone, or stubborn bumpy texture who want a science-based, fragrance-free solution. It suits most skin types seeking visible refinement and brighter skin, though those with very reactive skin should patch-test and introduce gradually. Ideal for anyone looking for an effective, concentrated booster to add to an anti-aging or resurfacing regimen.
