Compare Products: Clinical Niacinamide 20% Treatment vs B3 Nice 10% Niacinamide Serum
Ingredient Analysis
Both serums center on niacinamide and antioxidant blends, but they serve different goals. Paula's Choice Clinical Niacinamide 20% Treatment focuses on brightening and gentle hydration with vitamin C derivative and soothing botanicals. Sunday Riley B3 Nice 10% Niacinamide Serum leans into anti-aging and skin-repair with resveratrol, centella actives, and richer emollients.
Paula's Choice Clinical Niacinamide 20% Treatment has ascorbyl glucoside, acetyl glucosamine, and licorice extract all targeting uneven tone. Sunday Riley B3 Nice 10% Niacinamide Serum brightens mainly via niacinamide and diglucosyl gallic acid.
Sunday Riley B3 Nice 10% Niacinamide Serum contains centella actives (asiaticoside, madecassoside), resveratrol, and stabilized curcumin, all supporting collagen and skin repair. Paula's Choice Clinical Niacinamide 20% Treatment lacks this depth.
Paula's Choice Clinical Niacinamide 20% Treatment is fragrance-free with fewer preservatives. Sunday Riley B3 Nice 10% Niacinamide Serum adds fragrance, chlorphenesin, and ethoxydiglycol, raising the risk for sensitive skin.
Both contain glycerin and pentylene glycol as humectants. Sunday Riley B3 Nice 10% Niacinamide Serum adds betaine and octyldodecanol; Paula's Choice Clinical Niacinamide 20% Treatment adds panthenol. Hydration profiles are comparable.
Sunday Riley B3 Nice 10% Niacinamide Serum stacks resveratrol, multiple polyphenols, stabilized curcumin, and plant extracts. Paula's Choice Clinical Niacinamide 20% Treatment is solid but narrower in antioxidant diversity.
- •Niacinamide concentration is undisclosed in both products; efficacy depends on it reaching at least 2-5%.

- •Centella actives (asiaticoside, madecassoside) in Sunday Riley B3 Nice 10% Niacinamide Serum appear after several other ingredients, so their concentration may be low.
- •Resveratrol is notoriously unstable; formulation and packaging quality determine whether it remains active.
- •Tetrahydrodiferuloylmethane is a stabilized curcumin form, but clinical data on topical efficacy is limited compared to niacinamide or retinoids.
- •Parfum/Fragrance in Sunday Riley B3 Nice 10% Niacinamide Serum is a catch-all term; specific allergens are undisclosed.
- •Product identity for both inputs is unknown; no brand or product name could be confirmed.

User Feedback Patterns
Users who found the 10% booster insufficient often report better results with this formula, particularly for aging-related pore concerns and textural issues.
The gel texture feels slightly oily to some users before it dries down. Some report a tacky feel or that it takes time to absorb. Most find it works well under moisturizer.
Some users report sensitivity, flushing, or irritation — especially if used daily from the start. Several reviewers recommend using every other day initially or finding 10% sufficient.
Like the 10% booster, results are typically seen over weeks of consistent use rather than immediately. Some users report noticeable improvement within 1-2 weeks; others need longer.
Users frequently praise the lightweight, watery texture that absorbs quickly without stickiness. Layers well under other products and makeup.
Consistent reports of improved radiance and brighter complexion with regular use, though dark spot fading varies by individual.
Oily skin users report reduced shine and less sebum production throughout the day.
Some users note the dropper packaging can cause product to dry and crust around the lid. Others have reported the product arriving discolored.
Mixed opinions on value. Some feel the botanical complex justifies the premium; others find it overpriced compared to budget niacinamide options.
Which Should You Buy?
