Paula's Choice Clinical 20% Niacinamide Face Serum, 0.67 oz — High-Strength B3 for Pores & Brightening

This concentrated face serum blends 20% niacinamide with brightening botanicals to target common signs of aging and sun-damaged skin without fragrance. The lightweight formula is presented in a small, precision bottle so you can add an effective actives boost to your routine—aimed at improving pore appearance, smoothing hard clogged bumps, and diminishing blotchy discoloration for a clearer-looking complexion.

How does this serum help with enlarged or sagging pores?

At a 20% strength, niacinamide works to tighten the look of stretched pores and improve overall pore function. By supporting skin surface renewal and reducing congestion, pores appear smaller and skin texture looks more refined.

• High 20% niacinamide concentration to visibly refine pore appearance
• Formulated to address sagging or dilated pores linked to aging and sun exposure
• Lightweight texture that layers under moisturizers and makeup

Can this serum improve uneven tone and discoloration?

The formula includes brightening extracts like licorice root that work with niacinamide to reduce the look of blotchy tone and areas of discoloration. Regular use helps create a more even, luminous complexion without adding harsh exfoliants.

• Licorice root extract for visible brightening of dull spots
• Targets blotchy pigmentation and sun-related unevenness
• Suitable for layering with sunscreen and other daytime products

Will this serum clear hard, clogged bumps and rough texture?

The concentrated niacinamide targets congestion that forms hardened bumps and rough, orange-peel texture. Over time it helps reduce the appearance of clogged pores and encourages a smoother surface—making skin look clearer and more even.

• Designed to reduce hard, congested bumps and improve surface smoothness
• Helps loosen and refine clogged pore buildup without harsh scrubbing
• Works alongside exfoliation routines if additional resurfacing is desired

How should I introduce this potent serum into my skincare routine?

Start slowly—use a small amount every other day to assess tolerance, then increase frequency if your skin responds well. Apply after cleansing and toning, before moisturizers; always follow with broad-spectrum sunscreen in the daytime.

• Begin with a patch test and gradual build-up to nightly or twice-daily use
• Use a pea-sized amount; layer under moisturizer
• Pair with SPF during daytime to protect improvements in tone and texture

Who is this for? Paula's Choice CLINICAL 20% Niacinamide Serum is aimed at people noticing enlarged or sagging pores, uneven tone, sun-related discoloration, and hard, clogged bumps who want a high-strength, fragrance-free active treatment. It's particularly suited to those experienced with concentrated actives seeking a science-driven booster to improve texture and clarity without added fragrance or unnecessary ingredients.
