Ingredient Analysis

Paula's Choice 10% Niacinamide Booster packs more skin-brightening and antioxidant actives. The Inkey List SuperSolutions 20% Niacinamide Serum keeps things simpler with sebum-regulating Zinc PCA and skin-softening squalane. The better pick depends on whether your goal is brightening or oil control.

Depends on skin goal: brightening and antioxidant protection versus oil control and texture refinement
How they differ
Brightening powerPaula's Choice

Paula's Choice 10% Niacinamide Booster combines Ascorbyl Glucoside, Acetyl Glucosamine, and niacinamide. The Inkey List SuperSolutions 20% Niacinamide Serum relies on niacinamide alone for brightening.

Antioxidant depthPaula's Choice

Paula's Choice 10% Niacinamide Booster includes EGCG, Genistein, Carnosine, and licorice extracts. The Inkey List SuperSolutions 20% Niacinamide Serum has no dedicated antioxidants.

Oil controlThe Inkey List

Zinc PCA in The Inkey List SuperSolutions 20% Niacinamide Serum directly regulates sebum. Paula's Choice 10% Niacinamide Booster has no equivalent sebum-targeting ingredient.

Skin barrier supportPaula's Choice

Phospholipids, Beta-Glucan, Panthenol, and Sodium Hyaluronate give Paula's Choice 10% Niacinamide Booster a stronger barrier-repair profile.

Irritation riskThe Inkey List

The Inkey List SuperSolutions 20% Niacinamide Serum's formula is shorter and simpler. Paula's Choice 10% Niacinamide Booster's pH adjusters and more actives raise the chance of sensitivity in reactive skin.

What the label does not tell us
  • •Niacinamide concentration is undisclosed in both products, which affects how meaningful the shared ingredient is.
  • •Ascorbyl Glucoside stability depends on pH and packaging. Opaque, airtight packaging matters significantly.
  • •Benzyl Alcohol in The Inkey List SuperSolutions 20% Niacinamide Serum can irritate sensitive or eczema-prone skin at higher concentrations.
  • •Genistein is a phytoestrogen. Its topical hormonal effect is considered low, but this is debated.
  • •EGCG degrades quickly when exposed to light or air. Formula preservation method is unknown here.
  • •Squalane source in The Inkey List SuperSolutions 20% Niacinamide Serum is not specified. Shark-derived and plant-derived versions both exist.

User Feedback Patterns

Paula's Choice
Texture takes adjustment

The watery, almost runny texture surprises some users. It can feel like it's not "doing" anything. The brand intends for it to be mixed with other products, which helps with application.

Price comparison to The Ordinary

At roughly 7x the price of The Ordinary's niacinamide serum, value is a common discussion point. Users who prefer it cite the more elegant texture, additional beneficial ingredients, and lack of pilling.

Gradual, cumulative results

Most users report noticing effects (smoother skin, smaller-looking pores, more even tone) after several weeks of consistent use rather than immediate results.

Plays well with other products

The booster format gets consistent praise for layering easily. Users report no issues combining it with retinol, acids, or other actives.

The Inkey List
Serious oil control

Users with very oily skin consistently report this as one of the most effective oil-control products they have tried. Many note all-day mattifying effect.

Strong but not irritating

Despite the 20% concentration, most users report no irritation. However, patch testing is frequently mentioned as important for first-time users.

Better than The Ordinary

Users who found The Ordinary's 10% niacinamide too weak or pilling-prone often prefer this. The gel texture absorbs cleanly.

Can leave white cast if overused

Some users report a white film if they apply too much. The brand addresses this: use less product and follow immediately with moisturizer.

Which Should You Buy?

The Inkey List SuperSolutions 20% Niacinamide Serum offers great value at a lower price point. Paula's Choice 10% Niacinamide Booster may be worth the premium if you want Niacinamide (10%).
