Common questions
Is L'Oréal Paris Age Perfect Le Duo Age Defying Serum fragrance-free?
No. Fragrance (listed as "Parfum") is the 61st of 61 ingredients.
Does L'Oréal Paris Age Perfect Le Duo Age Defying Serum contain alcohol?
Yes. Alcohol denat., a drying alcohol, is the 3rd of 61 ingredients, high enough to be a main ingredient. It makes products feel light and dry quickly, but can dry out or irritate sensitive skin.
Is L'Oréal Paris Age Perfect Le Duo Age Defying Serum safe for fungal acne?
It contains 3 ingredients that fungal-acne (Malassezia) guides usually avoid: polysorbates (polysorbate 20); plant oils & butters (argania spinosa kernel oil, glycine soja oil). How much they matter depends on the amount and the rest of the formula. The evidence comes mainly from lab studies of yeast growth, and fungal acne needs a diagnosis from a GP or dermatologist.
Is L'Oréal Paris Age Perfect Le Duo Age Defying Serum suitable for sensitive skin?
It contains fragrance and drying alcohol high in the list, which can bother sensitive skin. Patch-test it before using it all over.
