The verdict

Paying $23.99 more for La Roche-Posay buys you benzoyl peroxide.

La Roche-Posay Effaclar Duo adds benzoyl peroxide (strong evidence) that Good Molecules Niacinamide Serum doesn't have. On consumer consensus, Good Molecules Niacinamide Serum holds 4.3★ across 7,100 reviews vs La Roche-Posay Effaclar Duo's 4.3★ across 8,900 reviews. The extra $23.99 for La Roche-Posay Effaclar Duo is defensible for the added benzoyl peroxide.
