Common questions
Is Neutrogena Hydro Boost Ultra Light Hydrating Serum fragrance-free?
Yes. No fragrance, essential oils or fragrance allergens are listed in its ingredients.
Does Neutrogena Hydro Boost Ultra Light Hydrating Serum contain alcohol?
No drying alcohol (alcohol denat. or ethanol) is listed.
Is Neutrogena Hydro Boost Ultra Light Hydrating Serum safe for fungal acne?
It contains 2 ingredients that fungal-acne (Malassezia) guides usually avoid: fatty-acid esters & glycerides (cetearyl olivate, sorbitan olivate). 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 Neutrogena Hydro Boost Ultra Light Hydrating 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.
