The verdict

Paying $18.01 more for Paula's Choice buys you ascorbic acid.

Paula's Choice 10% Niacinamide Booster adds ascorbic acid (moderate evidence) that La Roche-Posay Effaclar Duo doesn't have. On consumer consensus, La Roche-Posay Effaclar Duo holds 4.3★ across 8,900 reviews vs Paula's Choice 10% Niacinamide Booster's 4.5★ across 4,100 reviews. The extra $18.01 for Paula's Choice 10% Niacinamide Booster is defensible for the added ascorbic acid.
