La Roche-PosayAnalysis updated June 2026 · How Scout scores
At a glance
Summary
This acne treatment contains methylparaben, a preservative associated with potential endocrine disruption, which negatively impacts its safety profile. While it includes beneficial active ingredients like adapalene, the presence of parabens and the overall processing level limit its score. The product is formulated without synthetic fragrances, which is a positive aspect, but the use of parabens and its ultra-processed nature prevent a higher rating.
