La Roche-Posay Mela B3 UV Daily Moisturizer Sunscreen, SPF 30

Editor's Take

This earns its treatment-sunscreen billing: 5% Niacinamide and Melasyl make it more useful for dark spots than the average SPF moisturizer.

Four-pillar formula scores

• Performance: 8.2 / 10
• Innovative Ingredients: 8.8 / 10
• Clean Standards: 6.7 / 10
• Formula Sustainability: 7.5 / 10

The Verdict

Amazon’s La Roche-Posay listing promises daily SPF 30 protection from sun damage, a no-white-cast finish, and dark-spot care from 5% Niacinamide and Melasyl. Titanium Dioxide supplies credible mineral UV protection, while Niacinamide leads the supporting ingredients and Melasyl adds targeted pigment-regulating chemistry; LHA and the liquid-crystal emulsion make this more purposeful than a basic face sunscreen. The ingredient list supports the protection and treatment rationale, but it cannot verify the no-white-cast finish across skin tones. Clean-formula appeal is middling because of fragrance, Phenoxyethanol, Carbomer, and synthetic acrylate polymers; those persistent polymers also temper an otherwise solid formula-sustainability profile. A credible daily sunscreen for someone treating dark spots, with stronger treatment credentials than its fragrance-laced base suggests.
