Common questions
Is The Ordinary Hyaluronic Acid Duo fragrance-free?
Yes. No fragrance, essential oils or fragrance allergens are listed in its ingredients.
Does The Ordinary Hyaluronic Acid Duo contain alcohol?
No drying alcohol (alcohol denat. or ethanol) is listed.
Is The Ordinary Hyaluronic Acid Duo 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. 2 of its ingredients aren't in our glossary yet, so check those yourself. The evidence comes mainly from lab studies of yeast growth, and fungal acne needs a diagnosis from a GP or dermatologist.
Is The Ordinary Hyaluronic Acid Duo 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.
