Common questions
Is La Roche-Posay Hyalu B5 Eye Serum fragrance-free?
Yes. No fragrance, essential oils or fragrance allergens are listed in its ingredients. La Roche-Posay also describes it as fragrance-free.
Does La Roche-Posay Hyalu B5 Eye Serum contain alcohol?
No drying alcohol (alcohol denat. or ethanol) is listed.
Is La Roche-Posay Hyalu B5 Eye Serum safe for fungal acne?
None of the ingredients usually flagged for fungal acne are listed: fatty acids with 11–24 carbons and their esters, polysorbates, plant oils and butters, or ferments. One of its ingredients isn't in our glossary yet, so check that one yourself. The evidence comes mainly from lab studies of yeast growth, and fungal acne needs a diagnosis from a GP or dermatologist.
Is La Roche-Posay Hyalu B5 Eye Serum suitable for sensitive skin?
Its ingredient list avoids the most common irritants: no fragrance, essential oils, drying alcohol or strong exfoliating acids are listed. Reactions are individual, so patch-test anything new.
