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

This fragrance-free, science-backed treatment combines a high 20% niacinamide concentration with clarifying extracts to target enlarged or clogged pores, uneven discoloration, and rough, bumpy skin. The lightweight serum absorbs quickly and is formulated for targeted use on areas that show age- or sun-related pore stretching and texture changes. It comes in a 0.67 oz bottle for focused, potent applications where skin needs renewed clarity and smoother surface appearance.

How does this serum visibly shrink and refine enlarged pores?

The formula uses 20% niacinamide to support improved pore appearance and skin surface resilience. Niacinamide helps regulate pore function and appearance over time while calming the look of stretched or sagging openings caused by aging and environmental stress.

• High 20% vitamin B3 concentration for targeted pore refinement
• Lightweight texture that penetrates without leaving residue
• Helps reduce the look of pore stretching from sun or age

Will this help with uneven tone, dark spots, and dullness?

The serum includes brightening botanicals such as licorice root alongside niacinamide to help fade blotchy discoloration and restore a more uniform tone. Regular use aims to reveal a more luminous, even complexion while minimizing the appearance of age- and damage-related dark spots.

• Licorice root extract supports visible brightening
• Targets blotchiness and sun-related discoloration
• Improves overall radiance for clearer-looking skin

Can it address hard, clogged bumps and rough, orange-peel texture?

This concentrated formula is designed to smooth coarse, congested texture by helping to loosen and refine clogged pores and hardened bumps. Over time, the serum contributes to a smoother surface and fewer visible irregularities without heavy exfoliants in the same product.

• Works on hard, clogged bumps and congested pores
• Helps reduce orange-peel or rough surface texture
• Supports clearer skin appearance with consistent use

Is a 20% concentration safe for regular use and who should patch-test?

The advanced 20% niacinamide level is formulated for visible results while maintaining a fragrance-free base to reduce irritation risk. If you have very sensitive or barrier-compromised skin, introduce the serum gradually and perform a patch test before applying broadly.

• Fragrance-free formula to minimize unnecessary irritation
• Start slowly if your skin is highly reactive; patch-test first
• Use in combination with your moisturizer and sunscreen routine

Who is this for: Paula's Choice CLINICAL 20% Niacinamide Serum is suited for people seeking targeted, science-driven correction of enlarged pores, stubborn texture, and uneven tone. It's intended for those comfortable using concentrated actives and who want a fragrance-free, fast-absorbing treatment to incorporate into evening or alternating-day routines. Avoid use on broken skin; consult a skincare professional if you have specific sensitivity concerns. For best results, pair with a consistent cleanser, moisturizer, and daily sun protection to protect improvements in tone and texture.
