Paula's Choice 10% Niacinamide Booster Review: Would Buyers Buy It Again?
Disclosure: As an Amazon Associate I earn from qualifying purchases. If you buy through links on this page we may earn a commission at no extra cost to you. How this review was made: We did not test this serum. This verdict is based on two reviewer write-ups, listed at the end. One is a single long-term user and the other an aggregator with unattributed expert notes, so evidence is thin and we say so. Our method.
Lightweight and easy to layer, but small for the price
Reviewers describe a thin, fast-absorbing serum that layers well, with visible smoother skin and tidier-looking pores over weeks. A long-term user has repurchased it several times and prefers it to The Ordinary. Drawbacks are the small bottle for a premium-priced product, a glass dropper that is awkward for travel, and some mild flushing at 10 percent. Those who like the feel are likely to rebuy; budget buyers may prefer cheaper niacinamide options.

How it holds up over time
We found only one long-term user account, from a reviewer who repurchased several times. That is encouraging but not strong evidence. The aggregator's expert section is unattributed and its citations looked inconsistent, so we did not rely on it for clinical claims.
Tips from owners
- Start with fewer drops and build up.
- Layer under moisturizer and sunscreen in the morning.
- Stop if irritation persists and see a dermatologist.
