Paula's Choice emphasizes science-backed ingredients with no unnecessary fillers, making this serum suitable for those seeking measurable texture and tone improvements.

How does this serum reduce the appearance of large pores?

The 20% niacinamide concentration helps support pore function and visibly tightens skin that looks stretched or sagging from age or sun exposure. Regular use refines the pore walls and can create a smoother surface, reducing the noticeable size of pores over time.

• High-strength 20% niacinamide to target pore laxity
• Lightweight, fast-absorbing texture for layered routines
• Improves pore function to help prevent future enlargement

Will this serum help uneven tone and dullness?

Yes — the formula includes brightening allies such as licorice root to address blotchiness and discoloration while niacinamide supports an even-looking complexion. Together they work to create a visibly more luminous and balanced skin tone without harsh exfoliation.

• Licorice root extract to reduce the look of dark spots and redness
• Niacinamide helps regulate pigment distribution for a more uniform tone
• Non-irritating approach suitable for combination with other actives

Can it smooth hard, clogged bumps and rough texture?

The serum targets congested pores and hard bumps that create an orange-peel appearance, helping to soften and smooth the skin’s surface. While not an exfoliating acid, it improves pore clarity and texture by supporting normal skin processes and clearing the look of clogged areas.

• Formulated to reduce the appearance of hard, clogged bumps
• Softens rough texture for a clearer, more even surface
• Use alongside exfoliating steps if additional resurfacing is needed

How should I incorporate this serum into my routine?

Apply a small amount after cleansing and before moisturizer, once or twice daily depending on tolerance and your current regimen. Because this is a concentrated booster, patch-test first and layer with sunscreen in the daytime to protect results.

• Use after cleansing and lightweight toners, before creams and oils
• Start with a few drops, increasing to desired frequency as tolerated
• Always follow with broad-spectrum SPF during daytime use

Who is this for: This serum suits people noticing enlarged or stretched pores, rough or clogged bumps, and uneven skin tone who want a targeted, science-backed treatment without fragrance. It’s particularly helpful for those experienced with active skincare interested in a potent niacinamide booster to refine texture and brighten skin.
