La Roche-Posay Effaclar Mat Mattifying Face Moisturizer for Oily Skin ingredients: is it worth it?
Good mattifying moisturizer, but an alcohol-heavy, fragranced base makes it a mediocre treatment for genuinely oily or acne-prone skin.

The efficacy score is 3.3/5: glycerin supports hydration, while silica, nylon-12, crosspolymers, and zinc PCA can reduce shine, but the formula is dominated by sensory mattifiers rather than robust treatment actives. Capryloyl salicylic acid and salicylic acid appear near the end, so their concentrations are likely modest; no disclosed acid percentage or pH supports strong exfoliation or acne treatment. Denatured alcohol at position 5 and fragrance further weaken the overall formulation quality, although the silicone-emollient base should provide a smooth cosmetic finish.
